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 6 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, documentation, API reference, and 23 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cequence: open an issue to ask a question, or submit a pull request to add artifacts.

  description: Enterprise AI Gateway that makes applications agent-ready through governed Model Context Protocol integration.
    Register a REST API from its OpenAPI spec (or proxy a third-party remote MCP server) and the gateway publishes it as an
    MCP endpoint with inbound SSO/OAuth/API-key/JWT authentication, outbound credential injection (OAuth 2.1 authorization
    or client-credentials, API key, bearer, JWT bearer, basic, passthrough), per-tool rate limiting, DLP redaction, circuit
    breaking, agent personas that compose tools across servers, a SKILL.md skill registry, and audit export to Splunk HEC,
    Datadog, OTLP or syslog. Cequence also operates a first-party hosted MCP server, provisioned for every tenant, that manages
    the gateway itself from any agent.
