API Security Testing

Tools and services testing application programming interfaces for vulnerabilities.

Market snapshot

These figures describe Application Security (AppSec) (9.1.1), the segment that API Security Testing sits within. They are not figures for API Security Testing on its own.

FragmentationConsolidatingEstimate

Not separately classified. AppSec sells to engineering budgets rather than security ones, which changes the buying motion entirely: adoption is bottom-up through developers, and the products that win are the ones that do not slow a build. Land-and-expand economics look more like developer tooling than like security.
