Your cloud isn’t broken. That’s why risks go unnoticed. Access grows, permissions drift, visibility fades.

Underneath, your environment is becoming harder to control with every change.

Fix it before it becomes a problem.

Security tip: Disable PowerShell remoting for standard users. Attackers use it for lateral movement. Only admins should have PowerShell access to M365.

Before buying another tool, ask yourself: Have we actually configured what Microsoft already gives us?

Hot take: MFA alone doesn't mean your M365 is secure.

I've seen tenants with MFA enabled everywhere that were still wide open because:
- No Conditional Access policies
- Legacy auth still allowed
- No device compliance requirements
- Open external sharing

MFA is step 1 of 100.
