Know which Microsoft 365 tenants can be exploited. Right now.
TenantGuard monitors every Microsoft 365 tenant across your MSP portfolio, maps real attack paths, and confirms which ones are exploitable — continuously.
MSPs manage 20–50 client tenants. Checking each one manually is impossible.
Knowing you have misconfigurations is not enough. You need to know what an attacker can actually do with them.
Your clients are exposed right now. You just do not know which ones.
We confirm exploitability.
Not just misconfiguration.
Most security tools give you a list of issues. TenantGuard's Safe Exploitability Validation Engine tells you which attack paths are CONFIRMED exploitable in your client's environment right now.
Validated against MITRE ATT&CK cloud technique framework
Attack path is fully exploitable right now. Immediate action required.
Partial conditions exist. Monitor closely and remediate soon.
Compensating control prevents this attack path.
Built for MSPs. Designed for scale.

Built in the UK for UK MSPs
TenantGuard was built to solve a problem every UK MSP faces — managing Microsoft 365 security across dozens of client tenants with limited time and limited tooling.
We map real attack paths, validate exploitability in real time, and give your team the intelligence to act before attackers do.
Security by design
Read-only access — TenantGuard never modifies your client tenants.
No credential storage — tokens are never saved to disk or database.
MITRE ATT&CK aligned — every rule maps to a real threat technique.
