What is API Security?

API security encompasses practices and technologies that protect application programming interfaces from unauthorized access and data exposure.

API security addresses the protection of APIs that transmit personal data between systems, applications, and third parties. With organizations increasingly relying on API-driven architectures, APIs have become a significant attack surface for personal data exposure.

Secure API design for personal data includes authentication (API keys, OAuth, JWT), authorization (scope-based access), encryption (TLS), rate limiting, input validation, and audit logging. ProtectIQ can apply data protection controls at the API layer, including field-level encryption and dynamic masking of personal data in API responses.
