Hi everyone! New here and trying to figure out the security scanning landscape for our CI pipeline.
We're currently comparing Checkmarx SAST and JFrog Xray (for SCA). Our main goal is to catch as many real vulnerabilities as possible before deployment, but we're worried about noise.
For those who have used both in CI: which one actually catches more *actionable* issues in your experience? I'm especially curious about how they handle modern JavaScript frameworks and Java Spring Boot apps. Does one consistently find things the other misses?
I'm a lead DevOps engineer at a mid-sized fintech (~200 devs) running Java Spring Boot and React microservices, and we've had both Checkmarx SAST and Xray (via Artifactory) in our CI pipelines for about two years now.
1. **Primary vulnerability focus.** Checkmarx primarily identifies custom code flaws (OWASP Top 10, business logic, hardcoded secrets), while Xray's core function is scanning dependencies for known library vulnerabilities (CVEs). They are complementary tools covering different risk layers. For a Spring Boot app, Checkmarx finds injection flaws in your controllers; Xray flags a vulnerable `log4j-core` JAR in your final container image.
2. **"Actionable" signal-to-noise ratio.** In our pipeline, Xray generates far fewer false positives for its domain because it's matching dependency hashes against CVE databases. Checkmarx requires significant tuning of its query set; out-of-the-box, it flagged ~30% false positives on our React code (e.g., JSX event-handler XSS findings that were sanitized by the framework). Reducing this to a manageable ~10% took about 80 hours of query tuning per major application.
3. **Integration and operational model.** Xray operates as a sidecar to Artifactory, scanning artifacts post-build. It adds ~45-90 seconds to our pipeline for image scanning. Checkmarx requires a dedicated build agent or container for its engine; a full scan on a medium-sized service (~100k LOC) takes 8-12 minutes, which forced us to move it to a nightly schedule rather than per-commit.
4. **Real cost structure.** Xray's cost is bundled with Artifactory (roughly $20-30/user/month for the full platform in our volume tier). Checkmarx is licensed per-developer seat with an annual scan quota; our last quote was ~$180/developer/year. The significant hidden cost for Checkmarx is the ongoing maintenance of scan configurations and triage, which consumes about 4-5 engineering hours per week across the team.
Given your goal to catch more real vulnerabilities before deployment, I'd recommend Xray first if you lack consistent SCA, as its findings are almost always critical and immediate to patch. If you already have solid SCA, then add Checkmarx for the custom code coverage, but only if you can dedicate the initial ~2 weeks for tuning its rules to your specific frameworks. To make a clean call, tell us if you already have a software composition analysis tool in place and what your team's weekly capacity for tool tuning and alert triage is.
