Building a
digital immune system.

No one should be the last line of defense. Sentaro lives inside your tenant, knows what belongs, and deals with what doesn't.

Message

Every message, read the way an analyst would.

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.

Live
App

Every app that touches your tenant, with what it can reach.

The OAuth grants, the AI tools nobody approved, the abandoned integration from 2023 that still reads mail. Scope-level risk, per user.

Coming soon
Identity

Where you leak before anyone attacks.

Credentials in breach dumps, lookalike registrations of your brand and your suppliers, exposure that exists outside your tenant and arrives inside it later.

Coming soon
Behavioral

What a user does, against their own normal.

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 incident, four vectors

Attacks don’t stay in one category. Neither does the engine.

One impersonation chain, from the domain registration to the payout that never happened.

    No link, no attachment. Sentaro reads the ask itself and moves it out of the inbox.

    Second try: a “document viewer” asks for consent.

    Sentaro puts the unverified app and the scopes it was granted in the connected-app report. One-click revocation is coming soon.

    Third try: the mailbox stops behaving like its owner.

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

The same engine, threat by threat: business email compromise, invoice fraud and AI-written phishing.

Sovereign by design

Whose call is it when it matters?

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, a Swedish company, runs its own engine for firms that answer to a European board and a European regulator.

“We chose Sentaro because it gave us an extra layer of security without creating more work. It was quick to roll out and gave us the visibility we had been missing.”
