Mailprotector designs, builds, and supports email security products with a focus on zero trust architecture. Founded in 2000, the company started as an email filtering solution for web developers and has evolved to protect millions of messages daily. The company's approach centers on a patented zero trust email security model that operates on the principle that nothing gets through until it proves it belongs, contrasting with the traditional "trust first, filter second" approach. The company's product suite includes Zero Trust Email Security as its core offering, along with AI-powered threat intelligence that adapts to evolving attack methods, a Heads-Up Display for dynamic security insights, X-Ray Vision for translating security findings into understandable information, and email bundling features for managing message flow. Mailprotector primarily serves managed service providers (MSPs), offering them a channel-first approach to deliver email security services to their clients. The company positions itself around replacing complexity with confidence and moving from constant fixes to prevention-focused security. Their products aim to help MSPs transform email protection from a commodity service into a differentiated offering. Mailprotector operates with a partner success model, providing training and support to MSPs to help them implement and manage email security solutions for their end customers.
