Verified security briefings, practical guides, and operational playbooks for video, access, IT, identity, networks, and cybersecurity.
Foundational explainers and practical playbooks for common security and technology decisions.
Use the NIST Cybersecurity Framework to organize decisions across governance, protection, detection, response, and recovery.

An AI answer is only as authorized as the retrieval path behind it. Preserve source permissions, evaluate the current user at query time, deny uncertain matches, and test revocation before an assistant searches customer records.

AI memory can improve continuity while retaining sensitive or hostile context beyond the original exchange. Define what may be remembered, its provenance, tenant boundary, expiry, user controls, deletion path, and incident response before enabling persistence.
Read the guide
A chat transcript cannot prove which identity, permission, tool, parameters, approval, or downstream result produced a business change. Build a protected event chain around every AI tool invocation while keeping secrets and sensitive content out of routine telemetry.

An MCP server can expose data and executable tools to an AI client. Inventory the publisher, code, tool definitions, identities, token audiences, network destinations, versions, changes, logs, and revocation path before allowing production use.

An AI agent must not decide for itself whether its next action needs human review. Define consequential actions in policy and code, present the exact proposed effect, issue narrow expiring approval, detect compound actions, and preserve an accountable record.

Microsoft GDAP can narrow a partner’s access by role and duration. An MSP still needs task-based role design, controlled group membership, customer approval, monitoring, renewal, and a tested emergency path.

An MSP identity exposed to ordinary email and browsing can become a route into customer administration. Separate privileged operators, devices, policies, secrets, and monitoring from collaboration activity.

Disabling one directory account does not end an MSP technician’s access. Close sessions, groups, RMM and PSA accounts, vault permissions, customer-local identities, API tokens, recovery paths, and shared knowledge.
