Email security needed a new trust foundation, so we built it.

Traditional approaches to email security make trust decisions based on message sources or content analysis. But they’re too easily spoofed and manipulated, especially with the rise of AI. That’s why Shield’s zero trust foundation is built around each user’s unique communication patterns.

By automatically learning who your clients interact with and how they handle messages, Shield creates a trust network of verified contacts. Our adaptive intelligence (AI) uses behavior-based email filtering to personalize protection for each user, delivering only the emails they want with no extra effort required.

Email protection that evolves as quickly as threats do.

Phishing, spoofing, and impersonation attacks are constantly evolving—and legacy filters can’t keep up. Shield uses multiple layers of behavioral intelligence to detect and stop both known and emerging threats before they ever reach the inbox.

As attack patterns change, Shield adapts in real time—giving MSPs a smarter, self-improving defense that protects users from the latest phishing, impersonation, and spoofing tactics.

Other vendor’s security banners just create noise without adding any real protection. Instead, Shield’s Heads-Up Display shows real-time security insights that update instantly as you work. Using clear color signals—green means trusted, red means risky—these dynamic insights help you feel more confident with good messages and more careful with suspicious ones.

The HUD works with any email client, without any apps or plugins to install or update. It also serves another important purpose: one-click access to a key feature we call X-ray.

X-ray is the world’s most secure email client, letting you safely preview any message while revealing what’s happening behind the scenes. See inside each email to understand its true security story, explained in plain English so you can make confident, informed decisions.

“Every time users go into X-ray, it shows them exactly why something might be suspicious and teaches better security habits in real-time. It’s organic security awareness training.”

Not every email needs your attention right now, even if you want to read it eventually. Shield’s Bundler automatically collects these non-urgent messages in a separate folder, keeping your inbox focused on what matters most today.

You’ll get reminded to review your bundled messages on your schedule. Use Shield’s optimized reader view or stay in your email client; it’s your choice. With Shield’s reader view, AI-generated message summaries help you quickly get the gist of each email so you can move on with your day.

More capabilities and features you won’t find anywhere else because we do things differently here.
