Big 4 audits cost six figures and take months. Same depth, 14 minutes.
Built by people who ran 120-hour Fortune 500 M365 audits. Free 14-day trial.
The Origin Story
Our founder Michael ran a Fortune 500 M365 security assessment entirely by hand — 120+ hours of manual data collection across Exchange, Teams, SharePoint, Intune, and Entra ID. That engagement is why 365 Security Assessment exists: to give every organization access to that depth without the time and cost of a consulting engagement.
Read-only access only. No changes to your tenant. Results in minutes.
What Changes — and What Doesn't
What 365SA replaces
- Manual screen-share data collection sessions
- Consultant hours spent pulling Exchange and Intune configs
- Spreadsheet-based compliance mapping per framework
- Point-in-time snapshot that goes stale immediately
- Sample-based spot checks at enterprise scale
What 365SA doesn't replace
- Your auditor's interpretation and risk narrative
- Executive risk-acceptance conversations in the room
- Regulatory signoff and board-level credentialing
- Broader GRC, IR retainer, or financial audit services
365SA automates the data-collection phase — the part that consumes the most hours and delivers the least strategic value. Your auditor owns interpretation, risk signoff, and executive narrative — and starts from real data instead of a clipboard.

The Manual Audit Timeline
A typical Big 4 M365 security assessment consumes weeks before findings reach your team. Here's where 365SA changes the equation.
Manual / Big 4 Engagement
Kickoff & scoping
SOW signed, kickoff call, stakeholder interviews, access provisioning
Manual data collection
Screen-share sessions, clipboard config reviews, spreadsheet population — 80–100 hours
Analysis & report drafting
Senior consultant review, risk narrative, compliance mapping — 20–40 hours
Delivery & readout
Final report delivered. Already stale by the time it lands.

Three Ways 365SA Changes the Audit
These aren't incremental improvements. They fundamentally change what's possible for your auditor, GRC team, and security leadership.
From 120 Hours to Minutes
365SA was born out of a 120-hour Fortune 500 M365 audit that our founder ran entirely by hand. Every step of that manual data-collection process is now codified into the platform — so the same depth that used to take a quarter shows up in minutes.
- All M365 workloads assessed simultaneously — not one at a time
- Every configuration inspected — not a sample selected by a consultant
- Repeatable results — no variability based on who was staffed
The Big 4 data collection problem
Manual M365 audits are sample-based by necessity. No consulting team has the capacity to inspect every mailbox setting, every Teams policy, every Conditional Access rule in a 30,000-user environment within a reasonable engagement budget. Coverage gaps are inevitable.
365SA at enterprise scale
Built for 30,000+ users. Every configuration, every policy, every setting — assessed in the same amount of time regardless of tenant size.
Point-in-time reality
A Big 4 report is accurate on the day it was drafted. Microsoft 365 tenants change constantly — new admins, new policies, new external sharing settings, new Conditional Access rules. Within weeks of delivery, material gaps may have opened that aren't in the report.
365SA continuous coverage
On-demand and scheduled scans keep your security posture current. When a Conditional Access policy drifts or a new admin is added, the report reflects it — instead of waiting until next year's engagement.
Continuous, Not Point-in-Time
A Big 4 engagement gives you one snapshot. 365SA scans on demand and on a schedule, so your security posture is always current. The report reflects your tenant today — not six weeks ago when the consultant was on-site.
- Scheduled rescans — weekly, monthly, or on-demand
- Drift detection — alerts when posture degrades between scans
- Always-current evidence for ongoing compliance programs
Same Evidence, Ten Frameworks at Once
The same scan that powers your executive summary produces per-control evidence across 10 compliance frameworks simultaneously. Manual audits price each framework as a separate line item; 365SA produces them together by default from a single assessment.
- HIPAA, GDPR, SOC2, FedRAMP, HITRUST, NIST 800-53, CIS M365, ISO 27001, CMMC, PCI-DSS
- Per-control evidence — not spreadsheet narrative
- All 10 frameworks from one scan — no additional engagement scope
Manual audit pricing reality
Each compliance framework adds scope, hours, and billing. A HIPAA + SOC2 + FedRAMP engagement is typically priced as three deliverables. Hand-built mapping spreadsheets age quickly and require re-validation each engagement cycle.
365SA framework coverage
One scan. Ten frameworks. Auditor-ready evidence per control across all of them. Your auditor still owns the interpretation — 365SA provides the data.
