Before you choose
Start with access and cost
A free plan can let you evaluate a tool without a paid contract. Items offering free plans include Akto API Security Platform, 42Crunch API Security Platform, Beagle Security and Endor Labs.
Pricing starts at different levels. 42Crunch advertises plans from $9 per user per month, while Beagle Security lists annual-billing plans from $99 per month and a 14-day trial.
Match testing coverage
Compare the testing methods listed for a tool with the checks your application needs. Review whether software composition analysis and API testing are included.
Tools in this category cover application security work, but the listed comparison fields differ. Check the method, SCA and API entries before choosing.
Check languages and CI/CD
Review supported languages against the code you maintain. Then compare CI/CD integrations so scans can fit the build and release flow.
The directory compares languages supported and CI/CD integrations as separate fields. Use both when narrowing the list.
Choose a deployment model
Options in the listings span web, Linux, Windows, API, self-hosted and macOS environments. Pick a setup that matches your operating environment and control requirements.
