Real-Time Defense Against Business Email Compromise

At the heart of Barracuda Sentinel is the AI engine that detects and blocks socially engineered attacks in real-time and identifies the employees who are at highest risk.

Unique API-based architecture gives Sentinel’s AI engine access to historical email data to learn each user’s unique communications patterns. The engine leverages multiple classifiers to map the social networks of every individual inside the company and identifies anomalous signals in message metadata and content.

Sentinel’s unique approach does not rely on static rules to detect targeted attacks— it relies on historical statistics of each organization to determine with a higher degree of accuracy whether a certain email is part of a socially engineered attack or account takeover.

Protection Against Account Takeover and Insider Risk

Every day, legitimate business accounts get compromised due to stolen credentials. The account takeover can remain dormant in your environment for months, with hackers watching and learning before launching their attacks. Any internal attacks launched from a compromised account often don’t pass through gateway and therefore go undetected.

Barracuda Sentinel’s comprehensive solution to account takeover includes three components: prevention, detection, and remediation. Barracuda Sentinel prevents targeted phishing attacks that bypass traditional email gateways and can lead to harvesting credentials. If an account has been compromised, Barracuda Sentinel detects the anomalous behavior and alerts IT. Finally, Barracuda Sentinel can remediate the attack by removing all of the malicious emails sent by the compromised account from within employee mailboxes with one click.

Brand Protection and Domain Fraud Visibility

Domain spoofing and brand hijacking are a common technique used by hackers in social engineering attacks. Domain spoofing can be used to target organization’s employees, customers, external partners, and other third parties that would trust its brand. Barracuda Sentinel provides complete protection from email domain fraud through DMARC (Domain-based Message Authentication Reporting and Conformance) reporting, analysis, and visibility.

Barracuda Sentinel offers an intuitive wizard to help companies easily set up DMARC authentication. Once DMARC is properly configured, it provides granular visibility and analysis of DMARC reports to help customers properly set-up DMARC enforcement and reduce the potential of false-positives enforcements.

Well-configured DMARC enforcement ensures deliverability of legitimate email traffic and prevents unauthorized spoofing emails.
