About

Salt Security protects the APIs that form the core of every modern application. Its patented API Protection Platform is the only API security solution that combines the power of cloud-scale big data and time-tested ML/AI to detect and prevent API attacks. By correlating activities across millions of APIs and users over time, Salt delivers deep context and actionable intelligence with real-time analysis and continuous insights for API discovery, attack prevention, and shift-left practices. Deployed quickly and seamlessly integrated within existing systems, the Salt Security platform gives customers immediate value and protection, so they can innovate with confidence and accelerate their digital transformation initiatives.

By delivering context-based insights across the entire API lifecycle, Salt enables users to detect the reconnaissance activity of bad actors and block them before they can reach their objective. Through its unique API Context Engine (ACE) architecture, the Salt platform provides design analysis in pre-production, discovers all APIs, pinpoints and stops API attackers, and provides remediation insights.

Salt Security was named a cool vendor in "Cool Vendor in API Strategy, 2020" by the Gartner Research Group.
