Barracuda Sentinel

Leverage Artificial Intelligence and kick away the Phish!

Deployment Options: SaaS

Barracuda Sentinel uses AI to learn an organization’s communication history to predict and prevent future attacks.

Barracuda Sentinel is powered by an AI engine that detects and blocks spear phishing attacks in real time. The AI engine automatically learns the unique communication patterns of each individual organization. It uses this knowledge to find anomalous signals in the attributes of the incoming message metadata and content. Barracuda Sentinel combines these signals to determine with a high degree of accuracy whether an email is part of a spear phishing attack. If identified, spear phishing attacks are quarantined in real-time, and the recipient and administrator are notified of the attempted attack.


Spear phishing is rapidly becoming the most significant security threat. Countless organizations and individuals have fallen prey, sending wire transfers and sensitive customer and employee information to attackers impersonating their CEO, boss, or trusted colleague.

Barracuda Sentinel is the first comprehensive AI solution to guard against targeted attacks, for real-time spear phishing and cyber fraud defense.

It’s a cloud service – no hardware or software to install or maintain,  and set-up takes less than five minutes. It connects directly to Office 365 via API, so there's no impact on network performance, user experience, or your existing email security architecture.

Barracuda Sentinel combines three powerful layers – artificial intelligence, domain fraud protection, and fraud simulation training – into a comprehensive solution:


AI engine learns existing communications patterns inside a company to identify anomalies and stop impersonation attempts and spear phishing attacks in real time, and the AI engine identifies high-risk individuals inside the company

Domain fraud protection using DMARC authentication to guard against domain spoofing and brand hijacking

Fraud simulation training to test the security awareness of high-risk individuals

The FBI reports that spear phishing has cost organizations $5 billion (see report). Beyond the financial impact, these attacks can cause irreparable damage to your reputation and brand. Because the attacks are highly personalized—and typically contain no malicious attachments or links—existing security solutions fail to detect them.
