MX Logic

MX Logic was a provider of on-demand email and web security services, founded in 2002 and headquartered in Englewood, CO. The company specialized in delivering enterprise-grade security solutions through a Software-as-a-Service (SaaS) model, focusing on ease of use and cost-effectiveness.

The firm's core offerings included the Email Defense Service, which provided comprehensive protection against threats such as spam, viruses, worms, phishing, and malware. Key features of its service portfolio were advanced spam blocking, virus and worm scanning, content and attachment filtering, fraud protection, and outbound message filtering. Additionally, MX Logic provided solutions for email archiving and business continuity, ensuring service availability and disaster recovery.

The company's business model was centered on providing managed security services to a broad client base, including corporations and service providers. By the time of its acquisition, MX Logic served 40,000 customers, protecting over four million end-users.

In July 2009, McAfee announced its acquisition of MX Logic for approximately $140 million in cash. This strategic move was aimed at strengthening McAfee's security-as-a-service portfolio by integrating MX Logic's email and web security technologies. The acquisition was completed in the third quarter of 2009. The MX Logic services were eventually marked for end-of-life in late 2016, with support officially ending in January 2017.
