Salt Security is the leader in agentic and API security, protecting the world's most innovative enterprises from AI agent and API attacks. Agentic security is the practice of discovering and governing the relationships between LLMs, MCP servers, and the APIs that let AI agents take action. The Salt Security Agentic Security Platform secures the full agentic ecosystem, discovering all agents, MCP connections, and APIs, stopping attacks in real time, and eliminating vulnerabilities before they reach production. Salt Security was founded in 2016 and is backed by Sequoia Capital, S Capital, Tenaya Capital, Salesforce Ventures, Advent International, and other leading investors.

Salt Security protects APIs for large enterprises. Many of them will not send their traffic to anyone else's cloud, so they run our platform themselves - inside their own data centres and their own cloud accounts. The Edge team builds and ships what those customers run: the container images, the Helm charts, and the multi-region delivery that puts it all in their hands.

What will you do?
Who are you?
Counts for a lot: having shipped anything a customer installs and runs themselves - on-prem software, an appliance, an agent, an air-gapped install, a released library you then had to support.

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.
With a total funding of $271 million, Salt Security has a valuation of $1.4 billion. Its latest $140 Series D round, led by CapitalG, Alphabet's independent growth fund, included participation from all existing investors, including Sequoia Capital, Y Combinator, Tenaya Capital, S Capital VC, Advent International, Alkeon Capital, and DFJ Growth.
Salt Security holds the only granted patent for using AI to identify and prevent API attacks and is the only solution that automatically and continuously discovers all APIs. This approach enables a complete and up-to-date inventory of all APIs. The Salt API security platform leads the market with the simplest, most comprehensive, and most effective API security offering.
