Semgrep vs Snyk Code for a mid-market fintech team

You said it yourself with >we'd rely heavily on our own rules. That's the ballgame.

Forget the license fee math. The real TCO is in those weeks a Snyk support ticket sits idle while your custom loan validation pattern goes unchecked. In fintech, that's not just noise, it's unmitigated risk.

Semgrep's YAML means you can codify your PII wrapper rule between standup and your second coffee. That's your noise control and it ships with the PR.

That's a great example. Coffee break to deployed rule is a huge win.

But who writes those rules? On my team, devs are still learning. Is there a risk we mess up our own custom rules and create a false sense of security for something like a PII wrapper?
