API Sentinel by Cequence Security discovers, monitors, and tests your APIs, assessing risks that can lead to compliance issues, data loss, and business disruption. API Sentinel is part of the Cequence Unified API Protection platform or available as separate Security Compliance and Security Testing modules. It offers continuous API discovery, inventory, and risk assessment. API Sentinel identifies vulnerabilities and other issues that could be exploited. It deploys at the network level and requires no server- or client-side agents, JavaScript, or SDK integration. This approach ensures API discovery and compliance is not limited to instrumented systems, eliminating penalties like extended development cycles, slow page loads, and increased cloud costs. API Sentinel integrates with existing infrastructure such as API gateways. It automatically identifies all your API endpoints – documented, undocumented, third-party, and shadow APIs to create a runtime API catalog. Discovered APIs are inventoried and assessed for risk related to access control, sensitive data leakage, and compliance with the published API specification. API Sentinel uses ML-based rules with predefined criteria to identify sensitive data. A graphical dashboard displays results with details such as the API source leaking data and the pattern found. Integrated API Security Testing empowers IT and development teams to test APIs, including those associated with Large Language Models (LLMs), identifying and remediating vulnerabilities and coding errors in pre-production and at runtime. It autonomously generates API specs without human involvement, eliminating significant manual effort. API Sentinel supports CI/CD pipelines, IDEs, or stand-alone testing. It helps companies create comprehensive maps of their API footprints, continuously updated for threats. Risk factors include deprecated and shadow API endpoints, coding errors, or lack of conformance with specifications like OpenAPI. API Sentinel contributes to understanding your API risk posture and includes automated API discovery services and ongoing API threat detection and prevention capabilities.
