What if the attacker is already inside a trusted account?

The most damaging emails often come from real accounts: a supplier whose mailbox was compromised last week, or a colleague whose credentials were phished. Authentication checks pass, the sender is familiar, and reputation-based filters wave the message through. One prospect came to us after their current tool missed exactly that: an internal account takeover.

Questions in this article

Can you tell when a trusted vendor's account has been taken over?

This is one of the most common things we find in head-to-head evaluations. A compromised vendor account looks legitimate on every surface signal, so AegisAgents investigate what the message is asking for, how it departs from that sender's normal behavior, and where its links and attachments really lead. The evidence, not the sender's reputation, decides the verdict.

Do you detect compromised internal accounts?

Yes. AegisAI alerts on signs that an internal mailbox has been taken over, so your team can respond before the account is used against colleagues and partners.

Can you ingest signals from our identity provider?

AegisAI combines its own email-side evidence with identity context, and we build integrations with identity providers based on customer demand. If your IdP isn't on our list yet, tell us: the combination of email and identity signals gives higher-fidelity detections than either alone.

Is remediation automatic?

Account takeover detection is delivered as alerts today, with the investigation evidence attached so your team can act quickly. Talk to us about your remediation workflow.
