Verdict and action
Who is really asking, from where, and whether the ask fits the relationship. Labeled in the mailbox so the recipient sees the verdict where they see the mail.
The OAuth grants, the AI tools nobody approved, the abandoned integration from 2023 that still reads mail. Scope-level risk, per user.
Credentials in breach dumps, lookalike registrations of your brand and your suppliers, exposure that exists outside your tenant and arrives inside it later.
Forwarding rules, off-hours sessions, data movement that fits nobody’s pattern. The signal that remains when the credentials are real and the message was legitimate.
One impersonation chain, from the domain registration to the payout that never happened.
Sentaro flags it before it is ever used.
No link, no attachment. Sentaro reads the ask itself and moves it out of the inbox before anyone opens it.

Sentaro scores it against this user’s own baseline, ends the session and removes the rule.
