Protection from Spear Phishing & Cyber Fraud

Available today for Office 365, and coming soon to other platforms.



Barracuda Sentinel is a cloud-based service for Office 365 that stops spear phishing and other email attacks from reaching your user inboxes. It complements your existing email security without impacting network performance. Sentinel finds phishing emails already in your inbox and then scans every new email — including ones sent from internal mailboxes.

Business email compromise (BEC), spear phishing, and account takeover are today's top email threats. These hyper-targeted attacks trick employees into making terribly costly mistakes. Barracuda Sentinel combines artificial intelligence, deep integration with Microsoft Office 365, and brand protection into a comprehensive solution that guards against these potentially devastating attacks.

It only takes minutes to set up with zero need for IT administration.

Protection Against Account Takeover & Insider Risk

Brand Protection & Domain Fraud Visibility

Sentinel’s unique API-based architecture lets its AI engine study historical email and learn users’ unique communication patterns. It can then identify anomalies in message metadata and content, to find and block socially engineered attacks in real time.

Sentinel stops phishing attacks used to harvest credentials for account takeover. It detects anomalous email behaviour and alerts IT, then finds and removes all fraud emails sent from compromised accounts.

Domain spoofing is a common type of social engineering attack that targets your employees, customers, and partners. Sentinel helps prevent email domain fraud with DMARC  reporting and analysis.
