Why teams pick Vigilus
Evidence you can show, and nothing changes without approval
Evidence on every finding
Each finding shows what Vigilus saw in the tenant, its severity and why. Checks that couldn't run are reported as not run.
A preserved case file
During an incident, Vigilus keeps the original log records behind every timeline entry, with chain of custody. It works alongside the identity threat detection and response (ITDR) tool the client already runs.
Nothing changes without approval
A person approves every change. Vigilus takes a snapshot first, verifies the fix after, and rolls back if it doesn't hold.
Read-only app permissions. AI processing runs inside our own cloud environment. Your data never goes to the companies that build the models, is never used to train a model, and prompts are never logged.
