If cybersecurity were a house, email would be the front door. And unfortunately, attackers are not politely ringing the bell. Over 90 percent of successful cyberattacks start with phishing or business email compromise, which means your inbox is not just for newsletters and meeting invites. It is the frontline.

Most organizations already have some form of email filtering in place. That is good. But attackers know how to slip past basic defenses. They count on one message being misclassified, one user being distracted, or one bad link looking just believable enough. That is usually all it takes.

That is where Legion Gatekeeper comes in.

Legion Gatekeeper adds an extra layer of visibility and protection on top of your existing email security. It monitors email traffic that has already passed through your defenses and looks for threats that were missed or mislabeled. Think of it as the second set of eyes that actually stays awake during the boring parts.

When suspicious emails do slip through, Legion Gatekeeper allows administrators to quickly remediate them with message clawback. That means pulling dangerous emails out of inboxes before someone clicks, panics, or forwards it to accounting with “Is this real?” in the subject line.

Gatekeeper also increases visibility by feeding email telemetry into advanced detection and response workflows. This helps identify coordinated attacks faster and respond with human-led expertise, not just automated guesswork.

Email attacks exploit people, not just technology. Legion Gatekeeper helps close that gap by watching what others miss and responding when it matters most.

Because the inbox is not just where work happens anymore. It is where attackers start.
