Most security scanners are fucking garbage. They either miss the shit that'll actually get you pwned or flood you with false positives that make devs want to nuke security scanning entirely. I spent three weeks chasing "SQL injection" alerts in goddamn comments and dead code branches that haven't executed since 2019.
The question isn't whether you need security scanning - it's whether you need security scanning that actually works in production environments without driving your developers insane.
Checkmarx costs a fortune but it actually finds real security issues. The SAST scanner caught a crypto bug in our payment processing code that three other tools missed. Would've been a nightmare if that hit production. Academic research shows most SAST tools detect only 12.7% of real-world vulnerabilities, but Checkmarx performs better than the average.
The unified platform thing sounds like marketing bullshit, but it's actually useful. Instead of juggling SonarQube for code quality, Snyk for dependencies, and some other tool for containers, you get everything in one dashboard. The SCA component found malicious packages in our npm dependencies that would've been a supply chain attack waiting to happen. Security researchers recommend combining multiple testing approaches, which is exactly what Checkmarx One tries to do.
The Real Problems You'll Face
Your first month will be hell. Like, actually hell. You'll get 4,000+ alerts on day one and zero clue which ones will get you fired if ignored. That "AI-powered query builder" they demo is mostly bullshit - you still need someone who actually knows security to tune the queries or you'll be drowning in noise forever.
What Actually Works
The latest engine version is faster than the old one - scans that used to take 2 hours now finish in 30 minutes. Still not as fast as SonarQube, but decent enough for overnight builds. It supports most languages you actually use: Java, .NET, Python, JavaScript, Go. The official documentation lists all the languages it handles. The exotic stuff works but expect more false positives.
GitHub integration works once you survive their webhook nightmare. Their setup docs assume you're psychic about webhook endpoints. GitLab's similar - expect to burn half a day figuring out why your commits aren't triggering scans (spoiler: webhook URL was wrong). Azure DevOps integration damn near broke me - spent three days debugging why builds kept timing out, turned out their connector has memory leaks in v2.1.4.
The Expensive Part
Concurrent scans are where they get you. "Start" packages give you 1 scan for every 20 developers - so if you have 100 devs, you get 5 concurrent scans. That's not enough if everyone's pushing code at once. Expect builds to queue up during busy periods. Check their licensing documentation for the painful details.
Full packages give you 1 scan per developer, but cost way more. Budget accordingly or prepare for slow CI/CD pipelines. Pricing benchmarks show Checkmarx is expensive compared to alternatives.
Real Security Capability
The SAST scanner is legitimately good. It caught a path traversal vulnerability in our file upload handler that manual code review missed. The SCA database has solid coverage - it found a backdoor in a popular npm package before it hit the news. Vulnerability research shows their false positive rates are better than most competitors.
Container scanning works well with Docker. It caught our intern hardcoding AWS keys in a Dockerfile ENV statement (seriously, why?). Base image scanning found 47 critical vulnerabilities in that node:14-alpine
image everyone keeps using. The container security documentation covers setup, but expect Error: DOCKER_API_VERSION not supported
on newer Docker versions. API security discovered three debugging endpoints we forgot to disable - /api/admin/users/dump
was still live in prod, returning full user data.
The DAST component is hit-or-miss. Good for finding obvious stuff like unencrypted HTTP, but don't expect it to replace proper penetration testing. Security testing research suggests combining SAST with other testing methods for better coverage.
Bottom line
You're paying for consolidation and accuracy. Whether that's worth $60k+ depends on how much time your team currently wastes on security tool management and false positive hunting.
