Hey everyone. I've been tasked with evaluating SAST tools for my company—a large retail chain with a sprawling e-commerce platform, mobile apps, and a ton of legacy backend systems. We're looking at Semgrep as a potential addition to our security pipeline.
We currently use a couple of the big, expensive commercial scanners, and they're... fine. But they're slow, generate a lot of noise, and our dev teams find the results hard to action. Semgrep's speed and the ability for our own engineers to write custom rules is incredibly appealing. We have a lot of retail-specific logic (payment handling, inventory APIs, PII flows) that generic tools miss.
My question is for anyone operating at a similar scale. Is Semgrep actually "worth it" in an enterprise environment like ours? I'm particularly curious about:
* **Maintenance overhead:** How much effort is it really to manage a custom rule set? Does it become a full-time job?
* **CI/CD integration:** Does it hold up in a complex, multi-repo pipeline without grinding things to a halt?
* **The "Pro" tier:** We're looking at the paid version. Are the supplied rules and the dependency scanning robust enough, or are we better off building most things ourselves?
I love the idea of giving our platform teams the power to write rules for their own domains. The devs are already excited about the possibility. But I need to make sure it's not just a cool toy and can actually deliver consistent value at our scale. Any war stories or positive outcomes from similar shops would be super helpful.

Always testing.
I'm the Observability Tech Lead for a major logistics company with a similar scale, hundreds of microservices and 10k+ pipelines a day. We run Semgrep Pro in CI/CD alongside Snyk and a legacy commercial SAST tool.
1. **Rule Maintenance**: It's not zero, but it's not a full-time job either. You need a dedicated security engineer for 15-20% of their time to curate the central rule set, prune false positives, and write net-new rules. The real work is the triage process, not the rule writing itself.
2. **CI/CD Performance**: It's fast. Our scans average 90 seconds on a ~500k LOC monolith. For most microservices (under 50k LOC), it's under 30s. It's the fastest tool in our pipeline. The bottleneck becomes network/artifact pull, not the scan.
3. **Pro Tier Value**: The supplied rules are good for OWASP Top 10 and language-specific best practices. The dependency scanning is basic compared to a dedicated SCA tool like Snyk. You're paying for the management console, the audit logs, and the ease of distributing custom rules.
4. **Enterprise Limitation**: It's a *scanner*, not a *vulnerability management platform*. You will need another system to track findings over time, measure risk, and manage SLAs. The Pro dashboard is rudimentary for that. We feed results into Jira and our SIEM.
My pick: Semgrep Pro is absolutely worth it as a *complement* to your existing scanners for the custom rule capability alone. It's the only way we catch patterns specific to our business logic and internal frameworks. If your main need is a full-featured vuln management console, look elsewhere. For adding surgical precision and speed, it's the best tool I've used.
Metrics don't lie.
