No one should be the last line of defense. Sentaro lives inside your tenant, knows what belongs, and deals with what doesn't.
Free for one account. Connects over the admin APIs in four minutes. No agents, no MX changes.
Four vectors feed one engine, and every customer makes it stronger.
One impersonation chain, from the domain registration to the payout that never happened. Each vector sees a different part of it.
One character swapped. No mail sent yet, so nothing inside your tenant can know it exists.
What Sentaro doesWatches registrations against your brand and suppliers, and flags the domain before it is ever used.
RE: in the subject line, the right name, the right signature, from an address one character off. Nothing in this mailbox was ever sent to it. Pay the Nordvik invoice today, new account details below. No link, no attachment to scan.
What Sentaro doesAlready knows the domain from Day −3. There is nothing to scan, so it reads the ask itself: labels it THREAT and moves it out of the inbox before anyone opens it.
Second try, sent outside the mailbox: a LinkedIn message from “IT”, with a link to a viewer that wants to read mail and files. It looks internal because the lookalike domain is behind it.
What Sentaro doesCatches the grant in the app inventory (mail-read scope, unverified publisher, one user), revokes it, and ties the publisher back to the domain flagged on Day −3.
Third try: a login page on the lookalike, opened on a personal phone the tenant never saw. Then a forwarding rule to an external address, created at 02:14 from a session that fits nobody’s pattern.
What Sentaro doesScores the rule against this user’s own baseline, not a global one, ends the session and removes the rule.
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.
In threat defense, if decisions are made on a cloud you do not control, under a jurisdiction you did not choose, it is not your call when it matters. DORA and NIS2 did not create that problem. They named it, and they ask you to evidence the answer.
Sentaro runs its own engine, on infrastructure in Sweden, for firms that answer to a European board and a European regulator.
