This recognition adds to a growing list of accolades, including Shield’s recent win as the MSP Today Product of the Year and its nomination as a finalist in CRN’s 2025 Tech Innovator Awards.
Rethinking Email Security, Starting with Trust
Expert Insights recently recognized Mailprotector’s Shield as one of the best email security solutions for managed service providers. Built from the ground up for MSPs, Shield is changing the game by giving partners the power to protect inboxes without piling on complexity.
Email security is full of band-aid fixes. Traditional platforms try to block bad messages after they’re already in the inbox. Shield flips that script. It starts by trusting nothing. Every message has to earn its way into the inbox. That’s the power of Mailprotector’s zero trust foundation.
Or, as we like to say, “Every email starts with no.” That mindset changes everything.
With Shield, MSPs gain a layer of intelligent, adaptive protection that reduces noise and raises confidence for both partners and their clients.
It’s like noise-canceling headphones for your inbox. Suddenly, all the chaos just disappears.
Intelligent Email Protection That Learns Your Email Behavior (So You Don’t Have To)
What makes Shield stand out isn’t just its zero trust stance. It’s how it applies machine learning and behavioral analysis to learn what normal communication looks like for each user. From there, it builds a dynamic “circle of trust,” refining its model with every message you send, open, or ignore.
“Shield gives you back time you didn’t know you were missing.”
This means fewer false positives, fewer missed threats, and far fewer hours wasted managing quarantines. Shield doesn’t just block spam. It gets smarter every day, so MSPs and users can focus on what matters.
Why We Picked Mailprotector Shield: We rate Mailprotector Shield highly for its zero trust “circle of trust” model. It filters emails by learning trusted sender patterns and routing unverified ones to junk, effectively blocking AI-generated spam. (Expert Insights)
Designed for MSPs.
Some security products are built for the enterprise and retrofitted for service providers. Not Shield. Mailprotector built this platform exclusively for MSPs, with:
- 60-second deployments and no MX record changes
- A multi-tenant management experience that’s actually intuitive
- U.S.-based support from former MSPs who get it
It’s more than a tool. It’s an experience designed to make MSPs look and feel like security experts.
Tools That Clients Actually Appreciate Using
From the moment a message hits the inbox, Shield goes to work with:
- Heads-Up Display: Color-coded banners that show if a message is safe, suspicious, or dangerous
- X-ray View: A secure, non-technical preview that shows why a message was flagged
- Bundler: Rolls up non-urgent email into one easy-to-skim update
- So much more
It shows users exactly why something might be suspicious, building better security habits in real time.
Recognition Among the Best
Alongside Shield, Expert Insights also featured tools like TitanHQ Email Security, Libraesva, Proofpoint Essentials, and IRONSCALES. Each brings its own strengths, but none combine Shield’s blend of partner-first design, adaptive intelligence, and email experience that feels as calm as it is secure.
