ZeroBEC – AI Email Security for Microsoft 365

ZeroBEC is an AI-native email security platform that stops business email compromise, phishing, and credential-theft attacks before they reach the Microsoft 365 inbox. It integrates directly with Microsoft 365 through a single Global Administrator consent, requires no MX record changes, and starts analyzing email and identity signals within minutes.

Modern attacks bypass traditional secure email gateways using authenticated cloud senders, trusted hosting reputation, and identity workflows like device-code phishing and adversary-in-the-middle (AiTM) authentication. Passing SPF, DKIM, and DMARC no longer means an email is safe. ZeroBEC evaluates the whole attack - sender behavior, tenant context, link and content patterns, identity signals, and the recipient's own history - to catch BEC, credential-harvesting kits, quishing, device-code phishing, and AiTM campaigns that authenticated at the perimeter and still landed in the inbox.

Microsoft 365 organizations of any size - from lean teams with no dedicated security staff to security teams that keep seeing phishing land despite an existing gateway, and want AI-native detection without ripping out their stack.

Activation is a single consent from a Microsoft 365 Global Administrator - no MX changes, no mail-flow rewiring, no client-side agents. The approving admin needs the Global Administrator role only; a mailbox or email license is not required. Console access is automatic once provisioning completes, and ZeroBEC immediately begins building an AI behavioral profile of your organization to sharpen detection over the first days of use.
