## Summary

Cole McMillan is most useful for practitioner accounts of Microsoft-focused internal IT, automation, and lean operations.

- Best for: A managed IT services provider or Microsoft cloud consultancy targeting lean internal IT teams.
- Not for: Consumer security or productivity campaigns aimed at non-technical households or individual consumers.
- Check first: Ask how Benchmark Companies and Vireo Systems are related and ask for terms.

### Takeaways

- A single-operator model for 150 users reported four times ticket volume and 90% faster initial response.
- Conditional Access policies were first put in report-only mode so effects could be checked before enforcement.
- Identity attributes and dynamic groups organize licensing, security policies, and device management in Microsoft 365.

## Main ideas

- **With one operator, the system must remove work—not just speed it up.**: Cole McMillan argues that a single IT owner supporting roughly 150 users across multiple sites cannot rely on manual triage. Their operating principles: centralize intake for requests and alerts, use identity as the control plane, and make automation the default—not the goal. Centralized visibility alone is a trap: without automation, it simply makes more tickets visible. Repeatable, low-complexity work should be handled immediately and without intervention, reducing touchpoints rather than making humans work faster.
- **Identity should be the control plane, not a per-user administrative task.**: In a Microsoft 365 build, Cole McMillan created a custom identity model using standardized attributes and dynamic groups. Identities are classified by account type, company, department, location, work persona, license profile, and role tier. Those attributes drive dynamic group membership, which targets licensing, security policy, device management, and future automation. The stated chain runs from identity and device attributes to dynamic groups, then to licensing and policy, compliance, access control, and validation. The priority is to stop maintaining access, licensing, and policy user by user.
- **Roll out risky controls in report-only mode and document the architecture.**: Cole McMillan argues that immediate enforcement creates avoidable operational risk. They deployed Conditional Access policies in report-only mode first to review real sign-in behavior, expected impact, device compliance, and emergency-access controls before enforcement. The build also used Windows Update pilot and production rings. Documentation covered identity attributes, dynamic group structure, role tiers, device categories, Conditional Access, compliance, endpoint configuration, LAPS, rollout gates, validation, and change control. As McMillan puts it, a system is not truly scalable if it only works because one person remembers how it was built.
- **Own the tooling instead of renting it—then scale with entry-level support.**: Two posts describe bringing tooling in-house. One migration moved Microsoft 365 licensing from GoDaddy management to a direct CSP model; another took the RMM stack fully off an MSP and into internal ownership. The sequence: clean up the environment, standardize device management, build automation to reduce manual work, and then add a Tier 1 hire for day-to-day support while Cole McMillan focuses on automation and system design. A Kaseya Certified Administrator certification for Datto RMM is presented as validation of a system already running in production, not as the milestone.
- **Use vendor events to test operating-model ideas, not endorse products.**: Cole McMillan attends vendor events and reports on platform direction, with the focus on how IT operates under real constraints. The recurring theme is the shift from managing tickets to designing systems that reduce them. Vendor roadmaps provide context; the stated value lies in conversations with peers and vendor practitioners about scale, automation, and execution. The posts offer no product recommendations, comparisons, or purchase guidance, so treat them as commentary, not endorsements.

## Partnerships

Cole McMillan's posts do not describe a partnership or sponsorship offer. All five cover internal IT work: migrating Microsoft 365 licensing, building identity and device management, rolling out Conditional Access, cutting ticket resolution time, and bringing an RMM stack in-house. Two describe attending vendor events or completing vendor certification as an employee representative: Kaseya Connect in Charlotte and an Atera event in New York. Atera and Kaseya appear as vendors whose products they use or study, not as sponsors. The posts include no media kit, rate card, sponsored-format example, or inquiry route. A brand considering a paid collaboration should ask for available formats, terms, and a contact route.

## Alternatives

- Sebastain Gomes: Choose Sebastain Gomes when the deliverable is a video-first teaching explainer rather than a deployment retrospective. Cole McMillan's posts promote a YouTube channel that has passed 17,000 views and covers Microsoft Entra, Microsoft 365, Azure, cloud, and security. One post lays out Authentication Context in Entra ID as a numbered video lesson: what the feature is, how c1 and c2 contexts are used, how it works with Conditional Access for step-up authentication, real-world use cases for granular access control, and how to configure and test it in Entra ID. A consultancy that wants an on-camera explainer on granular access control and phishing-resistant MFA, distributed to a video audience, gets a format and topic match that McMillan's text-only posts do not describe.
- Arvind Suthar: Consider Arvind Suthar when the buyer's task is compliance-framework mapping rather than a lean-team operating story. The posts promote 'Securing GCC High,' a freely available and continuously updated reference at docs.mindline.com, described in one post as 793 pages. It maps every Conditional Access policy to its 800-171 control and to the DoW CIO's 'Brilliant at the Basics' top ten, carries all 110 CMMC Level 2 controls plus 97 active Rev 3 controls with policy and process controls labeled rather than dropped, and adds a Copilot data-readiness chapter on securing and minimizing the data layer before Copilot is turned on. For a consultancy selling into GCC High, CMMC, or other regulated Microsoft 365 environments, the author of that reference is a stronger source on control mapping and assessor-facing evidence than a practitioner whose published record is a commercial tenancy build.
- Ajay G.: Ajay G. is the better pick when the audience is a small or mid-sized business owner or a non-specialist buyer deciding what minimum security tooling to buy. One post answers the customer question 'what is the minimal set of tools I need to feel secure and meet my compliance needs' with ten plain steps: know what you have, enforce MFA everywhere, patch regularly, secure endpoints, back up critical data and test it, limit access to least privilege, monitor for unusual activity, train people continuously, document lightweight policies, and keep assessing. It frames the market problem as a patchwork of overlapping point tools and compliance frameworks that read like legal textbooks—the framing an SMB-facing offer needs.
