Summary

Mayhem Security is a commercial application security testing cyber tool that rapidly generates thousands of tests and provides actionable insights for testing. It requires a license fee and operates as a library integrateable into CI/CD pipelines. It is designed for application developers, and its documentation positions it alongside similar appsec testing platforms. The tool was initially launched in 2012.

How Mayhem Security helps

Which inputs to my application cause it to crash or hang?

generates large volumes of malformed and edge-case inputs against the running code and flags the ones that trigger a crash, hang, or exception, with the specific input that caused it

Which of these crashes are actually worth fixing first?

groups failures by the underlying defect and reports which ones are reachable and reproducible, so triage starts from distinct bugs rather than raw failure counts

Is this API endpoint safe to expose, or does it choke on unexpected input?

drives the API with generated requests that deviate from the expected schema and reports which endpoints fail, time out, or return unexpected server errors

Did this build introduce a regression that wasn't there before?

runs as a step in the pipeline and compares results against the prior build's baseline, surfacing new failures that weren't present before the latest change

Where in the code does a given failing test actually go wrong?

traces the failing input through the execution path and reports the point of failure, so the developer isn't left with only a crash report to work from

Am I testing this application enough to trust the results?

tracks how much of the code has been exercised by the generated tests and reports coverage, showing which parts of the application have not yet been reached
