API Protection Reviews and Ratings

What are API Protection?

Gartner defines API protection products as a category of specialized stand-alone security products focusing on protecting APIs from exploits, abuse and access violations, and assisting in remediating API exposures. These products offer features such as API discovery, API security testing, API posture management and runtime protection utilizing behavioral analysis. They should provide coverage for the internal- and external-facing APIs, and third-party APIs that organizations may consume. API protection products are delivered as cloud-based and on-premises solutions. Deployment can be offered in-line by intercepting ingress/egress API calls or out-of-band by deploying agents on application workloads and/or scanning code repositories.
