API security
API security platforms help teams discover, assess, and protect the APIs that underpin modern applications, services, and integrations. As organizations adopt microservices, agentic AI workflows, and machine-to-machine integrations, APIs have become the primary attack surface. Traditional security tools often fail to cover business logic and contextual authorization, leaving sensitive data exposed. These platforms provide deep visibility into the API inventory, how endpoints are exposed (internal vs. external), and how they are consumed by both humans and autonomous machines. Where traditional web security focuses on front-end vulnerabilities or "known bad" signatures, API security is designed for modern ecosystem realities: Stateful Analysis: Detecting attacks that look like legitimate traffic but exploit the order or logic of API calls. Machine Identities: Validating mTLS and certificate-bound tokens for non-human callers. Schema & Spec Drift: Continuously comparing live traffic against OpenAPI/Swagger specs to identify undocumented changes. Agentic AI Risk: Protecting against prompt injection or data exfiltration via AI-integrated endpoints (e.g., Model Context Protocol).
