Get the Help You Need

EFA works with Gmail (via Chrome extension) and Microsoft 365/Outlook (via Office add-in). For Outlook, you'll need a Microsoft 365 subscription — older or on-prem versions aren't supported.

No. Your email stays private.

EFA analyzes technical signals — sender address, domain, reply-to fields, routing patterns. Your email content is processed locally and never leaves your device. We don't read your emails. We don't store them.

An email that looks right — until you look closely. One letter changed. One character added. A slightly different domain. Easy to miss.

EFA checks those details automatically — so you don't have to.

For Gmail: Install from the Chrome Web Store and grant access to your contacts.

For Outlook: Install from Microsoft AppSource — the add-in appears in your Outlook ribbon.

No tool catches everything. But EFA is built to catch what actually causes losses — before you act.

It detects the patterns used in real-world fraud, at the moment it matters most. For anything involving money, always verify independently.

Because scammers use the same patterns as legitimate emails. That's the reality.

EFA is designed to give you a moment to pause — not to block you. If everything checks out, move forward. That pause is the protection.
