Automated Microsoft 365 Security Hardening & Copilot Readiness Audit
Before you switch on Microsoft 365 Copilot or connect AI workflows, know exactly how your tenant is configured. Our automated read-only audit inspects 28 security, SharePoint permission, email authentication and device controls—and hands you a complete Red, Amber & Green action sheet.
Most Microsoft 365 tenants have drifted from best practice
Out of the box, Microsoft 365 is set up so staff can get working quickly—not so a regulated business is safe from invoice fraud, silent inbox forwarding rules, or accidental oversharing inside Microsoft Copilot.
Over time, temporary settings become permanent: an old scanner needed legacy authentication, three former managers still have Global Administrator rights, "Anyone with the link" sharing is open across SharePoint, and DMARC is still sitting on p=none.
Rather than guessing—or paying days of consultancy fees for a vague PDF—we run our Automated Microsoft 365 Hardening Audit against your tenant using read-only Microsoft Graph telemetry and live DNS inspection. Within 24 hours you get a complete 28-point Traffic-Light Audit Sheet with the exact portal path and PowerShell action for every gap.
Four simple steps, zero downtime
- 1. Public DNS & email spoofing scan (0 mins admin time) — We immediately test your MX, SPF, DKIM (
selector1&selector2), DMARC enforcement and MTA-STS records. - 2. Read-only Microsoft Graph inspection (10 mins on a Teams call) — You sign in once with a read-only Global Reader session while our audit script queries 28 controls across Entra ID, Exchange Online, SharePoint, Teams and Intune.
- 3. Traffic-Light Audit Sheet & Roadmap — Every control is graded Red (Action Required), Amber (Worth Hardening), or Green (All Good), complete with whether it works on your existing Business Standard licence or requires Business Premium.
- 4. Fix it yourself or let us lock it down — Every item includes step-by-step admin instructions so your internal IT can action it, or our Cardiff team at Alphabyte IT & AlphaSec can remediate the whole list for an agreed fixed fee.
Six domains covered in your Traffic-Light Report
1. Sign-in, MFA & Legacy Auth (6 checks)
Phishing-resistant MFA/passkeys, legacy IMAP/POP/SMTP blocking, Conditional Access geo-restrictions, SMS MFA retirement and Self-Service Password Reset.
2. Admin Accounts & Privileges (5 checks)
Global Admin count (2–4 rule), dedicated cloud-only admin accounts without daily mailboxes, break-glass accounts, and risky 3rd-party OAuth app consent.
3. Email Security & Anti-Spoofing (6 checks)
SPF hard-fail, DKIM 2048-bit signing, DMARC quarantine/reject enforcement, automatic external forwarding blocks, and suspicious inbox rule detection.
4. SharePoint, OneDrive & Teams (4 checks)
Anonymous link restrictions, guest access governance, external Teams messaging rules, and legacy SharePoint site link settings.
5. Copilot & AI Data Governance (4 checks)
"Everyone except external users" oversharing checks on HR/finance folders, Unified Audit Log verification, Shadow AI blocks, and sensitivity labels.
6. Backup, Devices & Secure Score (3 checks)
Independent cloud-to-cloud backup verification (beyond the 93-day recycle bin), Intune/Basic Mobility device encryption, and Secure Score posture.
One audit covering IT, Cyber Security & AI Readiness
Because AlphaOps, Alphabyte IT and AlphaSec are one Cardiff team at Connies House (established 2009), a single Microsoft 365 Hardening Audit gives you all three perspectives in one document:
- AlphaSec: Cyber Essentials compliance and protection against invoice and conveyancing fraud.
- Alphabyte IT: Day-to-day Microsoft 365 administration, licensing (Business Standard vs Business Premium), Intune and monitored backups.
- AlphaOps: Safe SharePoint permissions for Microsoft 365 Copilot and Power Automate workflow readiness.
