Internal Brief

Built for our own Managed Microsoft 365 practice, and for the businesses we run it for, where “we think it is configured correctly” is not an answer anyone should accept.

What We Built

A lightweight on-site appliance paired with cloud automation that runs continuous audits across a Microsoft 365 estate and reports drift against an audit-ready standard. Instead of a once-a-year manual review, the posture is checked continuously and the evidence is always to hand.

How We Approached It

A small on-site device runs scheduled checks against the tenant and feeds results to a cloud reporting layer. Findings are tracked over time, so the question is not just “is it compliant today” but “what changed, and when.” It is built to stand alongside the established audit tools, with a simpler footprint and a clearer monthly report.

Outcome

Compliance becomes a live signal rather than an annual event. When something drifts, it is visible immediately, with the evidence attached, which is exactly the standard we promise on every managed engagement.
