The email security cornerstone of the EFA family. Cloud-hosted AI filtering that stops phishing, BEC, and spam across Microsoft 365, Google Workspace, Exchange, Zimbra, and any other mail system you run.
Every product in the EFA family is built around the same idea: that the systems protecting your business should be honest with you about what they're doing. OpenEFA is where that idea started — a commercial email security platform that publishes its filtering decisions, its scoring breakdown, and its module behavior, instead of hiding them inside a black box.
OpenEFA pairs naturally with the rest of the family. EFAlifeline backs up the email OpenEFA secures, so a deleted or ransomware-encrypted mailbox can be restored to any point in time. EFAarchive takes the messages OpenEFA delivers and writes them into a tamper-proof compliance archive, with legal hold and eDiscovery search built in. EFASentry monitors the network and endpoints around the email — so if something is wrong outside the inbox, you know about it before it reaches the inbox.
Most customers start with OpenEFA. As email becomes the most reliably-protected part of their stack, they expand into the rest of the family.
