Cequence Security

Cequence Security delivers the Unified API Protection (UAP) platform, combining external API attack-surface discovery, posture and compliance analysis, inline runtime protection, and testing into a single solution for defending web applications, APIs, and AI endpoints against business logic abuse, bot attacks, and fraud. The Cequence product family is organized into API Spyder (agentless external discovery), API Sentinel (API inventory, posture, and compliance), API Spartan (runtime bot and abuse defense), API Security Testing (shift-left OpenAPI conformance and vulnerability testing), and Cequence Defender (inline reverse-proxy enforcement of API policy).

Cequence Security publishes 5 APIs on the APIs.io network. Tagged areas include AI Protection, API Discovery, API Security, Application Security, and Attack Surface.

Cequence Security’s developer surface includes engineering blog, product news, and 9 more developer resources.
