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.

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.


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
