Microsoft 365 Security Hardening
Lock down your Microsoft 365 tenant — and keep it locked down.
Microsoft changes settings constantly. Users invite guests. Admins toggle policies "just for a minute." We apply a hardened security baseline to your tenant, monitor for drift in real time, and automatically remediate risky configurations before they become incidents.
Default Microsoft 365 settings aren't built for your risk.
Out-of-the-box tenants leave MFA gaps, over-permissive sharing, legacy authentication, risky app consents, and audit logging that's only half on. Even hardened tenants drift — every new Microsoft release, every admin change, every onboarded user is a chance to slip backward.
Our hardening program closes those gaps once, then keeps them closed with continuous monitoring and automated remediation mapped to CIS, NIST, and your cyber-insurance requirements.
What's included
A complete hardening program — across every M365 attack surface.
Identity & access (Entra ID)
Phishing-resistant MFA, Conditional Access, legacy auth blocked, risky sign-in policies, Privileged Identity Management, and break-glass account governance.
Email & collaboration
Defender for Office 365 tuned, anti-phishing and impersonation policies, Safe Links, Safe Attachments, and tenant-wide external sender warnings.
Sharing & guest access
SharePoint and OneDrive sharing scoped to your risk, guest access reviews, anonymous-link controls, and Teams external federation locked down.
App registrations & consents
Risky OAuth app discovery, admin consent workflow, and removal of over-permissioned third-party apps that quietly read mail or files.
Audit logging & retention
Unified audit log enabled, mailbox auditing on for every user, retention policies for legal hold, and alerting on suspicious admin activity.
Compliance mapping
Every control mapped to CIS Microsoft 365 Benchmark, NIST CSF, and cyber-insurance questionnaires — so audits stop being a fire drill.
How it works
Assess. Remediate. Monitor — continuously.
Assess
We scan your tenant against a hardened security baseline and produce a prioritized risk report — usually within a day.
Remediate
One-click remediation closes the gaps that matter most, with predicted impact shown before each change so nothing breaks for users.
Detect drift
We continuously watch for setting changes, new risky apps, and Microsoft-side defaults that shift your posture overnight.
Prove value
Branded executive reports show posture over time, controls mapped to frameworks, and evidence ready for auditors and insurers.
