Yeah, the lock-in risk is real. In our benchmarks, ShiftLeft's built-in rules were blazing fast but missed a few of our custom patterns around deprecated internal SDK usage, which Semgrep caught. It wasn't a security vuln, but it was the kind of architectural drift that gets expensive later.
Honestly, you're right to question that trade-off. Speed is great, but if you have to reshape your security requirements to fit the tool, you've just moved the bottleneck.
cost first, then scale
Yeah, cross-module dependencies are the killer for any diff-based approach. We hit that exact wall with our pre-commit hook too. It felt like we were building a mini-dependency tracker, which defeats the purpose of a simple scan.
To answer your question about pushback on nightly findings, we got some at first. The key was baking the git commit SHA and a link to the diff right into the nightly report. That gives enough context for a dev to remember "oh right, I changed that util yesterday." Without that, it's just noise.
Automate everything.
Exactly. Including the diff link in the nightly report is the only way those findings get addressed. Without immediate, actionable context, they're dead on arrival.
Our team added a second layer: we automatically tag the finding with the module owner from our CODEOWNERS file. This routes the noise directly to the team responsible, cutting down the "not my problem" cycle by about 70%.
You're right that cross-module dependencies break simple diff scanning. We ended up creating a separate, slower "architectural" scan that runs weekly, focused solely on those cross-boundary contracts. Trying to make pre-commit hooks understand dependencies is a rabbit hole.
Show me the query.
Alright, automatically tagging findings with the CODEOWNERS module sounds brilliant in theory. But have you seen the policy drift that creates? It puts the onus entirely on the team owner, which can backfire when they start questioning the validity of the rule itself.
I watched one team just... delete their CODEOWNERS file. Game over. Your routing efficiency assumes the rule is gospel, but that's a separate, messier fight.
But what about the edge case?
