M365 Security Cleanup

Your Microsoft tenant is live, and probably overshared

A fixed-scope cleanup: MFA gaps, external sharing, former-employee access, admin sprawl, and backup blind spots, without a vague “security project.”

Overview

A project with edges, not an endless assessment

Microsoft 365 is powerful and dangerously easy to misconfigure. External links that never expire, contractors who still have access, MFA that isn’t enforced everywhere, and no real backup beyond recycle bins are common, even in otherwise careful companies.

Our cleanup is a fixed-scope engagement: find the obvious risk, fix what we can in the window, and hand you a written findings report. Automation and AI help inventory sprawl quickly; humans decide what to change and how to communicate it to staff.

How it works

From first call to steady state

01

Read-only discovery

We inventory identity, sharing, admins, and backup posture without breaking production on day one.

02

Remediate with change control

Fixes land in planned windows with communication your team can follow.

03

Report & next steps

A plain-language report plus optional path into managed services.

AI + human advantage

Faster inventory of messy tenants

Tenants accumulate junk. AI-assisted analysis helps surface stale guests, odd sharing patterns, and admin sprawl quickly so engineers spend time remediating, not hunting through endless portals.

  • Sprawl and stale-access candidates
  • Prioritized risk lists
  • Clearer reporting drafts
  • Humans approve every production change

Our rule of thumb

AI handles speed, pattern recognition, and the work humans burn out on, triage, summarization, after-hours answering, log noise.

Humans handle judgment, trust, and messy exceptions, architecture, escalations, and anything that needs a grown-up conversation.

Outcomes

What “good” looks like after we plug in

Reduced obvious risk

The gaps attackers and accidents love get closed deliberately.

Shared understanding

Ownership sees what’s wrong in plain English, not acronym soup.

A cleaner starting line

Managed services work better on a tenant that isn’t on fire.

FAQ

Common questions

Will this disrupt staff?

Some changes (like MFA) need communication and a short adjustment period. We plan for that instead of surprising people on a Monday morning.
