Perforce Klocwork is a commercial static application security testing solution by Perforce Software. Sec1 ProSAST is a commercial static application security testing solution by Sec1. Features, integrations, deployment and the company behind each one, side by side.
What our shortlists say about the one we picked.
Best for: Safety-critical embedded teams requiring MISRA and AUTOSAR compliance
The limitation is that Klocwork's language support is narrower than some competitors: C, C++, C#, Java, JavaScript, Python, and Kotlin. If your stack includes Go, Ruby, Swift, or other languages, you will need a supplementary solution. The hybrid deployment model works for teams with on-premises requirements, but the setup and maintenance burden is higher than a SaaS alternative. This is a solution for teams with dedicated toolchain engineers, not a plug-and-play solution.
