ZERO TRUST EMAIL SECURITY
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.
IT DOESN’T HAVE TO BE SO HARD
Why It’s Time to Replace Legacy Email Filters for Good
Clients Decide What's Safe
Every email demands a decision: Is it safe? Should I trust it? Most clients aren’t qualified to make these decisions.
No One Tool Can Do The Job
Legacy gateways can’t catch internal threats. API solutions react too late. You’re forced to stitch together multiple solutions to provide comprehensive protection for your clients.
Trust Is The Default Setting
Traditional tools make trust decisions for you. Anyone with your email address can demand your attention at any time, turning your inbox into an open door for distraction and risk.
THREAT INTELLIGENCE
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.
HEADS-UP DISPLAY
Dynamic security insights, never static banners.
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
Security findings made human.
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.”
Zachary Kinder, Net-Tech Consulting
“Shield applies AI technology in a really unique, impressive way. It looks at all my messages and then adapts what’s delivered based on my specific tendencies and preferences. Plus, the AI just gets better the longer that you use it, and that’s awesome.”

“Mailprotector has created something very special with Shield. It not only protects you from all the spam, phishing and other junk out there, but also gives you time back with its efficiencies. Love the product and would never go back, highly recommend!”

“When I first turned it on, I thought something was broken because I wasn’t getting mail. Then I found out it was all in junk, where it should be. I haven’t been impressed by a whole lot of products right off the bat, but this is a game-changer.”
Robert Prayfrock

“Forward-thinking, client-centric, innovative, and needed. Thank you, Mailprotector, for re-inventing being an email user. Shield is a solid winner and my team appreciates what’s been done to make our email swell and not hell.”

BUNDLER
Because some emails can wait.
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.
New Sender Review
We’ll notify you when someone emails you for the first time. You can trust or silence them right inside the message. Shield learns your unique preferences to automatically deliver only the emails you want.
Email Security Briefing
Catch up on everything you need to know about your email and see exactly what Shield is doing to protect you with intuitive dashboards. Schedule your briefing at a day and time that works for you.
Spotlight
Spotlight is the one place where users and admins can find any message, anywhere in the email stack, fast. Search recipes for common scenarios makes finding missing messages easy, saving time and margin.
Lockbox
Lockbox provides an extra layer of protection for sensitive emails. Messages can only be unlocked using multi-factor authentication, so your messages are secure even if your email account is compromised.
Burner Addresses
Not everyone deserves your real email address. Create temporary addresses on the fly, customize how messages sent to that address are delivered, and burn them when you want to stop receiving emails.
Shield Control
Control is the administrative side of Shield, built directly into the product interface. Manage your organizations, adjust risk levels, and easily respond to users’ requests to verify if an email is safe.
Spy Tracker Blocking
Marketing tools use pixel trackers to target you with advertising. And if they can do it, so can bad actors. Shield automatically removes spy trackers before they hit your inbox to protect your privacy.
VIP Pass
Anyone who emails you at this address will be trusted for immediate delivery. Messages are still run through the threat security layer first, so you’ll always know they are safe to interact with.
Enhances M365
Shield works with Microsoft 365, not against it. Shield even fixes some of the shortcomings of Microsoft’s security… like when messages you want get repeatedly put into junk or held in the quarantine.
