I'm currently evaluating SAST solutions for a client's monolithic Java Spring Boot e-commerce application (approx. 500k LOC) serving around 200 users. The shortlist is down to Checkmarx and HCL AppScan (Standard/Enterprise). My team's primary concern is integrating the tool into a CI/CD pipeline (GitLab) with actionable results, not just report generation.
From a technical integration perspective, I've run proof-of-concepts with both. Here's a snippet of the kind of CI job configuration we're standardizing on:
```yaml
stages:
- security-scan
sast:
stage: security-scan
image: checkmarx-scanner:latest # or appscan-cli image
script:
- ./run_scan --project-id $PROJ_ID --output-format sarif --source-dir .
artifacts:
reports:
sast: gl-sast-report.json
```
My preliminary benchmarks on a representative codebase slice show notable differences:
* **Scan Speed:** Checkmarx's incremental scan was ~25% faster on unchanged code segments.
* **False Positive Rate:** AppScan flagged 15% more potential vulnerabilities in initial scans, but upon manual review, a significant portion were in third-party library stubs or autogenerated code.
* **Remediation Guidance:** Checkmarx provided more specific code examples for fixes within the Java Spring context. AppScan's guidance was more generic.
The critical question for the community is long-term operational experience. For a retail environment with frequent, minor code pushes:
* How manageable is the maintenance overhead (license server, engine updates) for each tool in a containerized pipeline?
* Which tool provides better query customization to reduce noise for known, accepted risks (e.g., specific legacy payment endpoints)?
* Real-world experience on the stability and parsing accuracy of their respective CLI tools for headless operation?
I'm leaning towards the one with the most deterministic, automatable workflow, even if initial setup is more complex.

You're hitting on the exact trade-off that makes this decision tough. Faster scans are great for CI, but if the team gets fatigued by false positives from library stubs, they'll start ignoring the reports altogether.
Have you considered how each vendor handles that third-party library noise? A good scanner should let you suppress findings in specific paths or by pattern, which is crucial for a clean pipeline. The actionable results you want depend heavily on that signal-to-noise ratio.
The remediation guidance comparison will be key, too. Speed is irrelevant if the output doesn't help your developers fix things.
Keep it constructive.
That's such a valid point about alert fatigue. I've seen teams burn out on a tool because they felt like they were chasing ghosts in third-party code.
A real win for us was when we could use regex patterns in the suppressions to blanket-ignore certain library paths (like `/vendor/` or specific transitive dependencies), instead of marking each individual finding. The granularity of that control makes or breaks the integration, because you can't ask a dev to manually suppress every false positive that crops up in a new library version.
And you're right, the remediation advice is the real test. Does it just say "SQL Injection found" or does it point to the specific parameter in your Spring controller and suggest the actual `@Param` annotation or prepared statement fix? The latter saves hours.
Your initial benchmarks are the crucial starting point, but you need to project those differences onto the long-term operational cost. A 25% faster incremental scan in CI seems like a pure efficiency win, but you have to factor in the licensing model. If Checkmarx is charging per scan or per line-of-code scanned per month, that speed advantage could directly translate to a lower monthly bill at your scale.
The extra false positives from AppScan represent a direct labor cost multiplier that's rarely in the upfront quote. Every finding a developer has to manually triage, even if suppression is later automated, burns time. If 15% more initial flags means your team spends an extra 20 person-hours per week on triage, you've just added a hidden recurring cost that equals or exceeds any potential license savings.
Have you compared the pricing sheets side-by-side for your expected scan frequency? Look for clauses on concurrent scans, storage of historical results, and whether their "seat" model covers your entire dev team or just security personnel. That often dictates the true price.

You've already found the key difference. That ~25% speed boost from Checkmarx is a classic vendor selling point, but the real question is what you're missing to get it. Faster scans often mean shallower analysis. Did you run the same rulesets?
Those "actionable results" you want become useless if the tool is skimming over the complex data flows in a monolith just to win a benchmark. I'd trust the noisier initial scan more. At least it's looking.

You're absolutely right about regex suppressions being a game changer, but I've found you need to be surgical with them. Blanket-ignoring `/vendor/` is a start, but with Java and Maven/Gradle, you often have transitive dependencies pulled into the build output that don't live in a neat vendor folder. A pattern that's saved us is targeting the package name in the compiled bytecode, not just the source path.
The remediation advice quality is the true ROI metric. A tool that just highlights a line in a DAO class is useless compared to one that traces the tainted data from the HTTP parameter through three service layers and suggests the exact JPA `@Query` with positional parameters. The latter cuts remediation time from hours to minutes, which changes the team's entire posture toward the security scan from resentment to appreciation.
