Cloudmark provides carrier-grade messaging security and compliance solutions for mobile network operators (MNOs), internet service providers (ISPs), and hosting providers. The company protects over 1.5 billion users globally across more than 150 service providers. The company's platform delivers protection across multiple messaging channels including mobile messaging (SMS/MMS), email, rich communications services (RCS), and social media. Their solutions identify and block threats such as smishing, phishing, malware, and spam using predictive detection capabilities for both inbound and outbound messaging traffic. For mobile network operators, Cloudmark offers the Cloudmark Platform for Mobile, which provides SMS firewall capabilities, threat detection, and policy enforcement to help operators eliminate revenue leakage, reduce subscriber churn, and comply with mobile messaging regulations. The platform enables operators to supervise sender and messaging aggregator behavior while protecting subscribers from malicious content. For internet service providers, Cloudmark delivers email security solutions that protect against phishing, malware, and spam. These solutions are designed to reduce operational complexity and total cost of ownership for email platforms, serving as replacements or augmentations to in-house security systems. The company is now part of Proofpoint and continues to operate as a messaging security brand. Their technology focuses on content analysis and threat identification to help service providers maintain network integrity, enforce compliance requirements, and protect end users from evolving messaging-based threats.
