Email security that blocks the bad and keeps everything else.
TrustLayer Mail defends against phishing, malware and BEC attacks with inline protection, no MX record changes needed. Built-in encryption, policy-based controls and user-level quarantines mean no gaps, no excuses.
Every message is covered: inbound, outbound and internal. And with a fully indexed, Compliant Email Archive available, you'll find any email in seconds and stay compliant without the chaos.
Traditional email security is too slow, too shallow, and too scattered.
Phishing still gets through. Quarantines cause chaos. And no one knows where the archived emails went. The inbox is still your biggest risk surface, and your biggest productivity killer, when protection isn't built for the way people work.
Phishing, spoofing and malware still land in mailboxes. Gateways miss too much, and inline protection is rarely built in.
Confusing quarantines clog up mail flow and spike IT tickets. Archiving is slow, clunky and impossible to search when you need it.
Switching providers shouldn't mean rewriting your mail flow. Legacy tools rely on rerouting and workarounds instead of working with what you've got.
TrustLayer Mail:
Redefining email security.
Phishing, spoofing, malware and BEC blocked in real time. Inbound, outbound and internal. Inline scanning, so nothing lands without a check, with no delay you can measure.
Traditional MX routing or Microsoft 365 Transport Rules and Connectors: pick either, switch with a wizard. Both get the same quarantine engine and the same layers of protection.
The Compliant Email Archive, an add-on to Email Security within the Mail layer: unlimited, tamper-proof retention with fast eDiscovery. A compliance request, a legal case, or just a lost email. It's all there in seconds.
LinkScan rescans URLs at click time, not just at delivery. Delayed payloads, cloaking tricks and zero-hour threats caught even when the link looked clean an hour ago.
Policy-based encryption with the SecureMail add-on. Sensitive messages go out securely, and nobody has to think about it.
Don't just take
our word for it.

“When I saw a demo of TrustLayer's combined web, email and cloud (CASB) security platform at a trade show, I felt like I had stumbled across something that didn't exist.”
