Painless encrypted email. Just wrap the subject in brackets and send.

Email security needed a new trust foundation, so we built it. Traditional approaches, like gateway or API only, that make trust decisions based on message sources or content analysis aren’t enough anymore. They’re too easily spoofed and manipulated, especially with the rise of AI. That’s why Shield’s zero trust foundation is built around your unique communication patterns. By automatically learning who you interact with and how you handle messages, Shield creates a trust network of verified contacts. Our adaptive intelligence (AI) turns this behavioral data into personalized protection, delivering only the email you want with no extra effort required.

CloudFilter is a secure email gateway built to deliver full inbound and outbound protection anywhere you have MX record control: Microsoft 365, Google Workspace, on-prem servers, hosted environments, and POP/IMAP. That flexibility has made it the right fit for MSPs managing diverse client environments.

Mailprotector is the email security platform built for and with MSPs, helping partners eliminate email threats instead of simply reacting to them. Backed by a robust patent portfolio, our platform includes Shield, the industry's only zero trust email security solution, alongside CloudFilter, Bracket, and Radar to simplify email filtering, encryption, and email risk assessment. Our solutions combine centralized multi-tenant management with an intuitive experience for administrators and end users, helping thousands of partners better protect client inboxes without adding complexity.
