Main ideas
AI has made attacks faster than most defenses can handle · Measure and supervise automation; don’t treat it as full autonomy · Regulation has shifted the security divide from tools to strategy and accountability
Rob Harrison’s posts present a Sophos perspective on cybersecurity: how organizations can respond to faster, AI-assisted attacks; show that security controls reduce risk; and meet growing expectations around regulation and trust.
The clearest recurring argument is that having security tools is not enough if people must manually connect information across siloed systems or cannot explain whether their controls work.
Their posts connect that problem to Sophos Fusion and MDR, as well as to security strategy for organizations without deep in-house expertise.
Rob Harrison links cybersecurity product developments to operational and organizational problems rather than discussing technology in isolation.
In one post, they trace how attack timelines compressed from weeks to days, identify manual work across siloed tools as a defensive bottleneck, and present unified, AI-assisted defence as a response.
Another gives concrete operating claims for Sophos MDR—52% of cases resolved end to end by AI and an average 89 seconds to automated response—while specifying that analysts supervise the AI and handle cases needing a person.
Other posts widen the lens to control effectiveness, executive reporting, supplier accountability, and the evidence SMEs need to trust vendors.
Together, these examples show how a cybersecurity provider frames the connection between defence operations, security strategy, and business accountability.
The examples are company-focused; ask for independent evaluation of the claims if that matters to your campaign.
Rob Harrison’s posts argue that cybersecurity is being reshaped by AI-speed attacks, a strategy and governance gap, and a trust problem for smaller buyers.

The priority is not more tools but unified, evidence-based defense: systems that break silos, automate response while keeping analysts in charge, and make security posture clear to executives and customers.
AI has made attacks faster than most defenses can handle
Rob Harrison argues that security defenses were designed around human timelines, when attacks could take weeks, but AI agents have compressed that timeline from weeks to days.
Read more
The bottleneck, they say, is not weak tools but the manual collation of information across dozens of siloed tools, which leaves defenders slower than their adversaries. The proposed fix is to move beyond separate products and build unified cybersecurity defense systems.
The post contrasts weeks-long, human-paced attacks with attacks compressed to days by AI, arguing that most defenses still operate on the old timelines.
It presents Sophos Fusion as an AI-native defense system and says Sophos tested the theory in its own operations before developing the offering.
Measure and supervise automation; don’t treat it as full autonomy
In a Sophos MDR update, Rob Harrison reports that 52% of cases are resolved end to end by AI with no human intervention, and that the average time from alert to fully automated response is 89 seconds.
Read more
AI handles the high-volume path while analysts supervise and take cases that need a person. The post also points to new partnerships with OpenAI and Anthropic to bring frontier AI models into the defense system.
The post cites more than 42,000 protected customers and says Sophos MDR added stronger detections, wider integrations and lower mean time to respond. It also notes early access for AI Defense and CISO Advantage, and describes a balance in which AI resolves most cases while analysts handle exceptions.
Regulation has shifted the security divide from tools to strategy and accountability
Rob Harrison says regulations such as NIS2 have quietly redrawn a 'cybersecurity poverty line.' The divide is no longer whether an organization owns the right tools, but whether it can align them with strategy and use them correctly.
Read more
Corporate accountability also means weak suppliers pass on not just breach risk but regulatory exposure and fines. They point to a shortage of people who can provide strategy and governance, and say Sophos is working to close that strategy gap.
The post cites the claim that only 1 in 10,000 organizations has a CISO to frame the shortage of security leadership. It directs readers to a linked article for the fuller argument about how the cybersecurity poverty line is evolving.
For SMEs and MSPs, trust must be backed by evidence
Rob Harrison argues that trust is becoming cybersecurity’s real differentiator, especially for small and midsize businesses.
Read more
SMEs face bigger security stacks and more compliance expectations but often lack the in-house expertise to judge whether their tools and providers are genuinely reducing risk. As scrutiny of suppliers, including MSPs, increases, trust must be backed by evidence: transparency, third-party validation and clear reporting.
The post cites Sophos research finding that only 5% of IT leaders say they fully trust their cybersecurity vendors. It asks readers which single proof point they use to build customer trust today.
Security spending needs a business case executives, regulators and insurers can understand
Announcing Sophos's acquisition of Arco Cyber, Rob Harrison says many organizations with strong technology stacks still struggle to understand the return on their security investments or how those investments reduce risk.
Read more
They need to know whether existing controls work and communicate security posture clearly to executives, regulators and insurers. The acquisition is positioned as a step toward Sophos CISO Advantage, with the line that MDR scales operations while CISO Advantage scales security strategy.
The post links an acquisition announcement to a recurring customer and partner complaint: proving ROI and risk reduction.
The gap, it says, is not technology alone but the ability to show whether controls work and explain security posture to non-security stakeholders.
Answers the question newcomers are most likely to have: what is the core argument?
Read more
The post states it directly in a few paragraphs, making it the fastest way to understand the position before reading further.
Rob Harrison argues that security defences were designed for human-paced attacks that could take weeks, while AI agents have already compressed that timeline to days.
The bottleneck is not weak tools but the manual collation of information across dozens of siloed tools, which leaves defenders slower than their adversaries.
The proposed fix is to replace separate products with unified defence systems.
The post also announces Sophos Fusion as an AI-native defence system and says the theory was tested against Sophos's own operations before becoming an offering.
A linked article gives the longer explanation.
For brands planning a campaign
The clearest anchor for a co-authored article or webinar on machine-speed attacks and analyst-supervised automation: it combines the framing, problem statement and product example. A brand could build the piece around the shift from siloed tooling to unified defence, using the Sophos Fusion test as a worked example.
Shows the operational detail behind the AI-native defence argument.

Where the first post explains the thesis, this one gives the numbers and outlines the division of labour between automation and human analysts.
A company update combining launch news with operating figures.
Rob Harrison reports that Sophos Fusion launched globally with events across EMEA, APJ and the Americas; Next-Gen SIEM and a rebuilt XDR went generally available; and Sophos MDR added stronger detections, wider integrations and lower mean time to respond across more than 42,000 customers.
The post says 52% of cases now resolve end to end by AI, from alert to remediation with no human intervention, and the average time from alert to a fully automated response is 89 seconds.
Analysts supervise the AI and take cases that need a person.
The post also names new partnerships with OpenAI and Anthropic, and early access for AI Defense and CISO Advantage.
For brands planning a campaign
Useful for campaigns that need measurable claims rather than slogans.
The 52% and 89-second figures, along with the supervised-automation model, give a vendor a concrete way to discuss AI's role in security operations.
The named model partnerships offer a natural hook for a joint technical piece.
Answers a different question from the AI-defence posts: how does Harrison connect security spending to business outcomes?

It is the best starting point for assessing whether the commentary can reach an executive-level audience.
Rob Harrison announces Sophos's acquisition of Arco Cyber and describes a problem raised by customers and partners: organisations with strong technology stacks still struggle to show returns on their security investments or explain how those investments reduce risk.
They need to know whether existing controls work and communicate security posture clearly to executives, regulators and insurers.
The acquisition is positioned as a step toward Sophos CISO Advantage, with the line that MDR scales operations while CISO Advantage scales security strategy.
The post credits a Forbes article for the fuller account and welcomes named people from Arco Cyber to the team.
For brands planning a campaign
A strong basis for executive-facing content on security posture reporting, control validation and board communication. A co-marketing partner could use this angle for a roundtable or briefing aimed at CISOs and finance stakeholders rather than practitioners.

A newcomer who wants to understand why the commentary keeps returning to strategy and accountability, rather than products alone, should read this one.
Rob Harrison argues that regulations such as NIS2 have quietly redrawn what is described as the cybersecurity poverty line.
In this framing, the dividing line is no longer whether an organisation owns the right tools but whether it can align those tools with strategy and use them correctly.
Corporate accountability means that weak suppliers pass on not just breach risk but regulatory exposure and fines.
The post points to a shortage of people who can supply strategy and governance, citing the claim that only one in ten thousand organisations has a CISO, and describes Sophos as working to close that strategy gap.
It directs readers to a linked article for the fuller argument.
For brands planning a campaign
Supports content for governance and compliance audiences, including supply-chain risk and accountability under NIS2. The CISO-shortage framing also offers a route to a webinar or article on managed security strategy for organisations that cannot hire a senior security leader.
Shows a channel- and partner-facing side of the work that the other posts do not.

It is worth opening to see how this person frames trust for smaller organisations and how the posts engage their audience with a direct question.
Rob Harrison writes that trust is becoming the real differentiator in cybersecurity, particularly for small and medium-sized businesses.
SMEs face bigger security stacks and more compliance expectations, but often lack the in-house expertise to judge whether their tools and providers are genuinely reducing risk.
The post cites Sophos research finding that only 5% of IT leaders say they have full trust in their cybersecurity vendors.
As scrutiny of suppliers, including MSPs, increases, Harrison argues, trust has to be backed by evidence: transparency, third-party validation and clear reporting.
The post closes by asking readers which single proof point they use to build customer trust.
For brands planning a campaign
Best suited to channel and MSP-facing campaigns, where the audience is validating vendors on behalf of clients.
The emphasis on transparency, third-party validation and reporting gives a partner programme a ready-made content theme.
The closing question also shows Harrison inviting audience responses rather than only broadcasting.
Machine-speed attacks against human-timeline defenses
Harrison argues that AI agents have compressed attack timelines from weeks to days, while most defenses still depend on manual work across dozens of siloed tools.
Read more
The post names the mismatch as the core problem and calls for unified defense systems rather than larger tool stacks, then presents Sophos Fusion as the company's test of that idea.
Contrasts how attacks used to work with how they work now, then moves from the general problem to a specific company response.
For brands planning a campaign
A ready-made hook for a co-authored article or webinar on AI-driven defense: the compression argument gives a vendor a concrete problem to organize around. It reads as company positioning, so a partner should add outside evidence or customer detail to make it more than a product launch.
Analyst-supervised automation in managed detection and response
Harrison reports operational figures from Sophos MDR: 52% of cases resolve end to end by AI with no human intervention, and average alert-to-response time is 89 seconds.
Read more
Analysts supervise the AI and take the cases that need a person. The post also cites 42,000+ protected customers and new partnerships with OpenAI and Anthropic, plus early access to AI Defense and CISO Advantage.
Leads with company news, then supports it with specific numbers and a stated division of labor between AI and analysts.
For brands planning a campaign
The metrics give a vendor concrete material for a webinar or article on automation, and the 'AI plus supervising analysts' framing avoids an overclaim of full automation. A co-authored piece could test that balance against the audience's own escalation experience.
Harrison describes regulations such as NIS2 as having redrawn a 'cybersecurity poverty line': tools alone no longer separate organizations, and the difference is whether they can align those tools with strategy and governance.
Read more
The post cites a shortage of security leadership, noting that only 1 in 10,000 organizations have a CISO, and points out that supplier failures now carry regulatory exposure and fines for the buyer.
Starts with a regulatory shift, poses the shortage as an open question, and closes with how Sophos is trying to close the strategy gap.
For brands planning a campaign
Useful for content aimed at regulated buyers and executives, because the governance and accountability angle reaches beyond practitioners. A partner could pair the policy hook with practical steps for organizations that cannot hire a CISO.
Harrison argues that trust has become the differentiator for small and midsize buyers, who face larger security stacks and more compliance expectations without in-house expertise to judge whether tools and providers reduce risk.
Read more
The post cites Sophos research that only 5% of IT leaders fully trust their cybersecurity vendors, and says trust should look like transparency, third-party validation, and clear reporting. It ends by asking readers which proof point they use.
Uses a research statistic to frame the problem, redefines an abstract word ('trust') as concrete practices, and closes with a direct question to the audience.
For brands planning a campaign
The question format is directly reusable for a co-authored post or a webinar prompt, and the 5% figure is a quotable anchor. The posts show company content only, with no documented sponsorship or partner format attached to the topic.
Security ROI and communicating posture to executives
Announcing the Arco Cyber acquisition, Harrison says many organizations with strong technology stacks still struggle to show the return on their security investment or how it reduces risk.
Read more
They need to know whether their controls work and how to explain posture to executives, regulators, and insurers. They position CISO Advantage as the answer and frame the acquisition as scaling security strategy alongside scaled MDR operations.
Ties an acquisition announcement to a recurring customer complaint, then links the company's offering to that gap.
For brands planning a campaign
An executive-communication angle suits a CISO-facing webinar or article, since the ROI and board-reporting problem is stated in the buyer's terms. Because the post is acquisition news, a partner should build the argument beyond the announcement to hold an editorial audience.
The five posts point to one consistent affiliation: Sophos.

Rob Harrison writes from inside the company — describing "our own operations," saying "we're helping close this strategy gap," thanking Sophos product, engineering and marketing teams, and referring to "the 42,000+ customers we protect."
Other brands that appear (OpenAI, Anthropic, Arco Cyber) come up as Sophos initiatives, not as relationships Harrison holds personally.
Ask whether any sponsorship, affiliate arrangement, paid partnership or ownership stake exists; none is disclosed in the posts.

The posts use insider framing throughout: Sophos "put this theory to the test, using our own operations"; "at Sophos, we're helping close this strategy gap"; "the 42,000+ customers we protect"; and a thank-you to Sophos product, engineering and marketing teams for a launch. Across the posts, Sophos products and strategy are the subject: AI-native defense (Sophos Fusion), managed detection and response, next-generation SIEM, XDR, and CISO Advantage.
Harrison notes that Sophos's defense system "builds on new partnerships with OpenAI and Anthropic, bringing frontier AI models into the defense system."

The partnership is Sophos's, not a separate relationship between Harrison and OpenAI.
Harrison shared Sophos's announcement that it acquired Arco Cyber, framing it as a step toward Sophos CISO Advantage, and welcomed three named Arco Cyber people to the team.

Rob Harrison writes about the widening gap between the speed of AI-assisted attacks and the pace of most security operations.
Read more
The posts reviewed cover four connected subjects: machine-speed attacks against defenses built for human timelines; managed detection and response, where AI resolves most cases and analysts take the exceptions; a shortage of security strategy and governance skills as regulation such as NIS2 raises the stakes; and the difficulty smaller buyers have judging whether tools and vendors actually reduce risk.
The through-line: adding more tools does not fix the problem.
Breaking down silos between them and making security posture legible to executives, regulators, and insurers does.
Readers new to this work can start with the posts on attack timelines and MDR automation figures, then move to the governance and vendor-trust pieces.
Most posts point to a longer article with the full argument, so the shorter posts work best as entry points rather than complete treatments.

Deepen Desai writes from inside a security vendor about the same shift Rob Harrison describes: attackers using AI to compress defenders' response time, and the case for AI agents that reduce exposure, speed investigation, and close the loop with remediation.
Read more
Both explain vendor platform announcements by naming the operational problem first — fragmented tools, manual steps, incomplete visibility — and describe early access to frontier AI models from OpenAI or Anthropic as part of the defense stack. If you follow Rob Harrison for AI-era security operations, Deepen Desai covers the same ground from a different platform.
Deepen Desai's posts center on exposure management and zero-trust architecture, including hands-on testing of frontier models against attack scenarios. Rob Harrison's posts focus on managed detection and response metrics, the balance between analysts and automation, and the strategy and governance gap smaller buyers face.
Andy Elizaire makes the same core argument as Rob Harrison about AI and security work: AI is a force multiplier that processes events and speeds investigation, but it does not understand a business's risk tolerance or which system can safely be taken offline, so human judgment stays in the loop.
Read more
Both favor analyst-supervised AI over full autonomy and write short, plainly argued posts built around one clear claim.
Andy Elizaire frames the argument around leadership and workforce change, drawing on panel discussions and speaking engagements, and addresses ransomware readiness, identity, and telemetry. Rob Harrison frames it around vendor operations and commercial announcements, with concrete response-time figures and product news.
Albina Kolomiets shares Rob Harrison's practical, teaching-oriented approach: both turn a complex, gatekept landscape into a navigable route for smaller organizations.

Her post mapping six routes into UK defence for SMEs reads like their posts on regulation and vendor trust, which turn an abstract problem into concrete questions readers can act on. Both close by inviting reader input.
Albina Kolomiets writes about defence technology, procurement, and commercial scaling for SMEs rather than cybersecurity operations. Her posts are structured as step-by-step guides and market-entry maps, not analysis of attacks, detection, or response.
For a cybersecurity vendor campaign aimed at AI-driven defense and MDR, Rob Harrison offers a reach test among practitioners, but the posts do not establish audience match by role, seniority, geography, or company size.

They cover cybersecurity operations and strategy, including AI-compressed attack timelines, Sophos Fusion, MDR automation, CISO strategy, and SME/MSP trust.
The one measured audience figure in the posts is a LinkedIn follower count of 7,758 observed on 2026-10-08.
Before placing budget, ask for recent results on comparable topics, depth, and formats: impressions and engagement by job function, seniority, company size, and geography, plus follower demographics if available.
For professional attributes such as employer, occupation, or job seniority, ask whether they have audience survey results or another documented source.

Each is Sophos company content: the global launch of Sophos Fusion and next-gen SIEM, the rebuilt XDR going GA, an MDR milestone, the Arco Cyber acquisition, and links to longer articles Rob Harrison wrote for Sophos’s own channels.
They promote Sophos products and strategy from inside the vendor, rather than presenting an independent creator with disclosed sponsors or published terms.
None includes a sponsorship disclosure, rate card, media kit, partner list, audience specification, or inquiry route.
A co-authored article or webinar would need to be arranged through Sophos’s marketing or communications function, not a creator booking channel, and the terms would be set by that organization rather than published here.
Before planning a collaboration, ask Sophos for available formats and terms.
A cybersecurity vendor wants to raise its thought leadership on AI-driven defence and managed detection and response with a co-authored article or webinar on machine-speed attacks and analyst-supervised automation.
Read more
This campaign fits what Rob Harrison's posts already show them doing.
They make the machine-speed argument in their own words: defences were built for attacks that took weeks, AI agents have compressed that to days, and the real bottleneck is manual collation of information across dozens of siloed tools rather than weak products.
That gives a co-authored piece a ready-made problem statement and a clear turn from tool stacks to unified defence systems, with Sophos Fusion as the worked example.
The automation angle is equally clear: 52% of cases resolved end to end by AI, an average of 89 seconds from alert to fully automated response, and analysts supervising the AI and taking the cases that need a person.
The supervised-automation framing lets a vendor talk about where AI sits in a process instead of claiming full autonomy.
These themes recur across the posts, keeping the campaign within Rob Harrison's established lane.
Before committing budget, ask for impressions and engagement on comparable posts; the only published audience figure is 7,758 LinkedIn followers observed on 2026-10-08, with no breakdown by job function, seniority, company size, or geography.
The posts are company content promoting Sophos products and strategy, and three link to longer articles not included here.
A co-authored article or webinar would be arranged through Sophos's marketing or communications function, with terms set by that organisation rather than through a published creator booking process.
Ask for the linked articles and customer or third-party data to sit alongside the company figures; a launch-framed piece alone will not hold an editorial audience.
When to choose a specialist
A competing endpoint and EDR vendor wants Rob Harrison to publish an independent, sponsor-disclosed comparison of EDR platforms, with audience demographics guaranteed by role, seniority, and region, and an open booking route.
Read more
This is a poor fit as scoped, for three reasons.
First, the posts show a position that is not vendor-neutral.
All five are Sophos company content: the global launch of Sophos Fusion, next-generation SIEM and rebuilt XDR going generally available, an MDR milestone, the Arco Cyber acquisition, and links to articles written for Sophos's own channels.
They promote Sophos products and strategy from inside the vendor.
A rival vendor asking for a comparative platform review wants content that cuts against the role shown in the posts; readers would not take the comparison at face value.
Second, there is no published creator-side commercial format to plan around.
None of the five posts discloses a sponsorship or paid partnership, names a collaborating brand other than Sophos, or publishes partnership terms, a rate card, a media kit, a partner list, an audience specification, or an inquiry route.
A buyer cannot plan this campaign from published terms; ask Sophos's marketing or communications function about terms and whether Rob Harrison accepts paid collaborations.
Third, the audience cannot be validated against a demographic guarantee.
The only measured figure published is 7,758 LinkedIn followers observed on 2026-10-08, with no data by job function, seniority, company size, or geography, and no post-level engagement figures.
Ask for audience and engagement data before promising reach to a named role in a named region.
If the brand wants executive-facing thought leadership in the same lane rather than an arm's-length comparison, the fit test changes, and the first campaign above is the better route.
A worked campaign example
A worked angle for the AI-defence campaign: a co-authored webinar with a companion article, built on the shift from weeks to days and from tool stacks to a single defence system.
Working title: Weeks to days — what breaks when attacks run at machine speed.
Open by stating the compression claim plainly: adversaries using AI agents have cut attack timelines from weeks to days, while most defences still run on human timelines and manual collation across dozens of siloed tools.
The individual tools are not the failure — the seams between them are.
The middle section moves from problem to division of labour: what share of cases resolve end to end by AI, how long alert to automated response takes, and where a human analyst re-enters.
Show the figures rather than simply asserting them: walk through one case path from alert to remediation and mark each handover, so readers can see what the automation did and what the analyst decided.
The brand should bring data absent from Rob Harrison's posts — its own escalation, false-positive, or mean-time-to-respond data, and ideally a customer who can describe the handover in their own words.
Close with questions buyers should put to any vendor claiming AI-native defence: what proportion of cases resolve without a human, what is the mean time to automated response, who supervises the automation, and how are the results reported back.
For the webinar, 30 to 40 minutes works: roughly 15 minutes of argument, 15 minutes of case walk-through, and 10 minutes of Q&A. Seed the Q&A with the direct question format Rob Harrison already uses to prompt replies — asking the audience which proof point they use to show a control is working — to turn a broadcast into a discussion and produce quotable answers for follow-up content.
Practical next steps: request the two linked articles referenced in the posts to check the longer arguments, confirm co-author credit and disclosure wording with Sophos's communications function, and ask for engagement results on comparable past posts before committing budget.
Measure registrations from target job functions, questions asked in the session, and follow-up campaigns requested, not impressions alone.
If the vendor wants the channel-facing version of this argument, the SME and MSP trust material — the finding that only 5% of IT leaders fully trust their cybersecurity vendors, and the reframing of trust as transparency, third-party validation, and clear reporting — supports a separate campaign for a different audience.
Consider Andy Elizaire when a campaign needs a security-leadership voice on why AI should amplify analysts rather than replace them.
Read more
The posts argue that AI can process billions of events and cut investigation time, but still cannot understand a business’s risk tolerance or why taking one server offline could cost millions while another can be isolated immediately.
That makes them useful for a webinar or co-authored piece on analyst-supervised automation, giving a vendor the human-judgment argument to build around.
Elizaire also discusses AI-driven ransomware shifting from a backup problem to a readiness problem, and asks whether defences can make decisions at the speed attackers are beginning to operate.
For a vendor that wants to frame the argument around people, process and technology working together, Elizaire is a stronger choice than Rob Harrison for leadership commentary and panel discussion rather than company operating metrics.
The posts focus on commentary and conference reflections, not product or operating data.
They do not include automation rates, mean time to response or a detailed vendor platform launch.
Rob Harrison’s posts provide those concrete figures — 52% of cases resolved end to end by AI and an average of 89 seconds from alert to fully automated response — alongside a product-launch narrative.
For a campaign built around measurable workflow claims and a platform story, Harrison is the better fit; for a campaign sharpening the human-expertise argument for a leadership audience, Elizaire is.
Consider Deepen Desai when a campaign needs architecture-level detail on agentic security operations, closed-loop remediation and testing frontier AI models against real attack and defence scenarios.
Read more
The posts describe a launch built around unified exposure management and threat management, inline telemetry across network, identity, endpoint, cloud, AI and deception, specialised AI agents shaped by frontline SOC experience, and remediation through a Zero Trust Exchange.
One post reports observations from testing frontier models, including multi-step reasoning that can construct complex exploit paths rather than only scan for known CVEs, and the value of architectural context and environment grounding.
For a vendor seeking a webinar or article that goes deep on how AI-driven defence works in the platform and where model testing changes the threat picture, Desai is a better choice than Harrison for a technical, architecture-first treatment.
The posts are closely tied to one vendor’s launch and positioning, including named AI programmes and platform capabilities.
A competing endpoint or MDR vendor would need to substantially reframe the material to avoid the neutrality problem described in the fit assessment: it reads as vendor platform advocacy, not an arm’s-length comparison.
Harrison’s posts are also company content, but centre on a machine-speed problem statement and supervised automation figures that are easier to adapt into a co-authored thought-leadership asset.
If a neutral, cross-platform view is needed, neither is ideal; for technical agentic-SecOps depth tied to a specific platform, Desai is the stronger alternate.
Consider Albina Kolomiets only if the vendor’s objective shifts from AI-driven cyber defence thought leadership to UK defence market entry, SME access and commercial scaling.
Read more
The posts map routes into UK Defence for innovators, SMEs, exporters and early-stage dual-use companies, and argue that a great defence product does not automatically become a successful defence business.
That is useful for a defence-tech vendor explaining procurement, partnerships and sales capability.
For a co-authored article or webinar on AI-driven defence and MDR, Kolomiets would require changing the problem being solved.
Choosing Kolomiets means shifting from cybersecurity operating content to defence-sector commercial navigation.
The posts explain where UK defence SMEs can find support and cover the test-feedback-adapt cycle seen in Ukraine, but do not provide the AI-defence argument, product evidence or automation workflow detail the campaign needs.
The tradeoff is relevance: a defence-industry audience may find the route maps and commercial-scaling argument more immediately useful than a machine-speed MDR piece, while a cybersecurity buyer evaluating detection and response thought leadership gets little from them.
Rob Harrison's five LinkedIn posts cover AI-assisted attacks against defences built for human timelines, Sophos MDR automation figures, the strategy and governance gap that regulation such as NIS2 exposes, vendor trust for SMEs and MSPs, and reporting security ROI to executives, regulators and insurers.
Three posts link to longer articles that are not available here, so those fuller arguments are not assessed.
The posts carry no publication dates.
Comparisons with Deepen Desai, Andy Elizaire and Albina Kolomiets draw on two LinkedIn posts each, published between May and October 2026.
The posts do not mention earlier career history or a signature book, show or business, so context beyond these posts remains unresolved.
