SEG-Miss Database

This is the Cofense SEG-Miss sample database. Here, you will find real-world recent examples of dangerous phishing emails that bypassed popular Secure Email Gateways including the newer AI model driven products. These malicious emails landed in employee inboxes, and could pose an immediate threat to your revenue and reputation. Conversely, Cofense customers could rest easy because these threats we removed from their systems by Cofense solutions.

How did we see these failures?

Our network of over 35+ Million Cofense-trained employees, and our automated journaling, reports suspected threats in real-time to the PDC which powers our security platform. This database is driven by factual and verifiable data sent through our analysis process and vetted by our human team of experts - unique to Cofense.
