CALCULATOR 03 // 60-SECOND HARDENING & AI READINESS AUDIT

Zero-Trust • M365 Copilot • CIS Level 2

Toggle your organization's active controls:

1. Entra ID Conditional Access & Privileged Identity MFA enforced for all users, legacy auth blocked, and PIM for admin roles.

2. CIS Benchmark Level 2 Operating System Hardening Disabled SMBv1/NTLMv1, LAPS deployed, AppLocker, and encrypted RPC.

3. VLAN East-West Micro-Segmentation & Firewall Lockdown Servers, workstations, VoIP, and IoT isolated with inter-VLAN inspection.

4. Immutable Air-Gapped Backups (S3 Object Lock / Veeam) Ransomware-proof storage that cannot be deleted even with root domain credentials.

5. SharePoint / OneDrive Permission Audit for M365 Copilot Eliminated broad "Everyone" permissions before generative AI indexation.

6. MDM Zero-Touch Enrollment & Remote MAM Data Wipe Intune compliance baselines, BitLocker escrow, and corporate sandboxing.

7. SIP Trunk TLS Signaling & SRTP Audio Encryption Encrypted call streams protecting against eavesdropping and packet sniffing.

8. Documented & Annually Tested Disaster Recovery Runbook Live spin-up test of replicated VMs with measured RTO under 60 minutes.
