Comparison

Foundation Machines vs Snyk.

Snyk is a broad enterprise AppSec platform. Foundation Machines is lighter, PR-native and tuned for the AI stack. Honest split on where each wins.

Snyk is a mature enterprise application-security platform: SAST, SCA, container, IaC and a large rules library. Sebastion AI is much narrower, a security-only PR reviewer that posts inline PR review comments tagged with severity and CWE id. We are not trying to replace Snyk for regulated programmes; we are a faster, lighter option for teams who want AI-driven security review on every pull request.

Choose Snyk when

You need a single AppSec platform across SAST, SCA, containers and IaC, with audit trails for a regulated programme and a long-standing vulnerability database. Snyk is the safer bet when procurement is the harder constraint than developer adoption.

Choose Sebastion AI when

You want security review that lives inside the pull request and ships concrete fixes instead of tickets. Lighter to adopt, cheaper than Snyk Team, PR-native by default and friendly with whatever else you have in the pipeline.
