Best Interactive Application Security Testing Software in 2026

Interactive application security testing software examines applications during runtime, so fit depends partly on the systems and development process you need to cover. Compared on API testing, authenticated testing, instrumentation, and language coverage, the options also differ in runtime targets and deployment. CI/CD integration can be another point to assess alongside free-plan availability and paid-from pricing. Aikido CSPM, HCL AppScan, and Waratek IAST are among the entries shown. Use the listed testing and integration criteria to compare coverage with your applications and workflow needs.
