Vigilus for Microsoft 365

Your tenant has doors. Most are unlocked by default.

Microsoft and Google secure the platform. Your identities, access settings and data are yours to secure. Vigilus finds every open setting in your Microsoft 365 tenant, maps it to the frameworks you report on, and helps you close it.

See every door. Hear every alarm. Close every threat.
