About PMSS API

The Platform for Mobile Sender Security (PMSS) API is an interface for accessing cloud-based PMSS. PMSS is built on Proofpoint’s Cloudmark Safe Messaging Cloud infrastructure and is an industry-leading tool for protecting A2P messaging streams from abuse, spam, and other unwanted content.

Offering real-time message analysis and mitigation, it enables Campaign Service Providers (CSPs) and Connectivity Partners (CNPs) to focus on their messaging business while maintaining compliance and safeguarding their reputation by delivering clean, consistent messaging to the mobile network.
