Advanced Threat Detection
Barracuda's Advanced Threat Detection (ATD) combines behavioral, heuristic, and sandboxing technologies to protect against zero hour and targeted attacks. ATD automatically scans email attachments in real-time; suspicious attachments are detonated in a sandbox environment to observe behavior. In addition to blocking the attachment, the results are integrated into the Barracuda Real Time Intelligence System providing protection for all other customers.
