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.
Detections and alerts ride Secure Conduit Technology — the same hardened channel used across EFA Security — and feed EFAintelligence so a threat caught here is known family-wide.
EFA Security is collaborative by design. Every product connects through Secure Conduit Technology — one hardened, monitored channel — so when one attacker is caught on any product anywhere in the community, the threat is neutralized locally and its tradecraft becomes intelligence that protects everyone else. Seen once, known everywhere.
A bad actor hits any EFA product line — EFAgateway, EFAcanary, OpenEFA, and the rest. The threat is stopped and sanitized right where it lands, before it can do harm.
The threat signal is extracted and every piece of customer-identifying information is removed. What's kept is the attacker's behavior — never who they targeted.
The anonymized intelligence is recorded and distributed across the EFA community over Secure Conduit Technology — the same hardened channel the products already trust.
Every other EFA deployment now recognizes that attacker on sight. A threat one customer sees becomes a threat the whole community is already defended against.
Your data stays yours. EFAintelligence shares what the threat was — never who was targeted. Customer identity, message content, and identifying metadata are stripped before anything ever leaves your environment. You contribute to the community's defense without exposing your business.
