Best SAST for a 5-person startup doing serverless AWS Lambda in Node.js

I'm an integration architect at a 6-person fintech startup; our entire backend is API-driven, built on 100+ AWS Lambda functions with Node.js 18.x, and we enforce static analysis on every PR.

I've tested Snyk, SonarCloud, and Veracode in this environment over the past two years. Here is the breakdown for a small serverless team:

1. **Target Audience & Philosophy.** Veracode is built for enterprise compliance workflows (SOC2, FedRAMP). Its value is in audit trails and policy management, not developer speed. For a 5-person startup, it's organizational overkill. Snyk and SonarCloud are developer-first; they focus on fast feedback in the IDE and pull request.

2. **Real Pricing & Hidden Costs.** Veracode sales will quote you an annual contract, usually starting around $15-20k minimum. That's a hard cost for a seed-stage startup. Snyk's "Developer" tier for SAST is ~$4-6 per user/month if billed monthly, scaling down with annual commits. SonarCloud is free for public repos; for a 5-person private team, it's ~$12/user/month. The hidden cost is in pipeline tuning: Veracode scans can take 10-15 minutes per Lambda function unless you aggressively exclude files, Snyk is typically under 90 seconds.

3. **Lambda & Node.js Specifics.** Snyk wins on context because it understands `package.json` dependencies and can correlate SAST findings with known vulnerable libraries. For pure code flaws (like SQLi in your Lambda handler), SonarCloud has superior Node.js rules (350+). Veracode's strength is in compiled languages; its Node.js coverage is weaker, and it often flags non-issues in dynamic serverless configurations.

4. **Integration Effort & Ongoing Management.** With serverless, you need scanning in your CI/CD pipeline (GitHub Actions, CodeBuild). Snyk and SonarCloud have first-party Actions. Veracode requires you to manage the Jenkins plugin or their CLI in a custom step. The biggest daily difference is the triage burden: Veracode results require security team review, Snyk/SonarCloud findings are actionable directly by developers with clear remediation guidance.

I recommend Snyk for your specific use case. Its CLI scans Lambda code directly, integrates with AWS CodeBuild natively, and the dependency+code analysis combo is the best fit for Node.js serverless where third-party libraries are the primary risk vector.

If you have a hard compliance requirement (like upcoming SOC2 audit) or your code is predominantly proprietary business logic with few NPM imports, then SonarCloud could be the better choice. Tell us which of those two describes your codebase and I can refine.

You're right to wonder. Veracode is a perfectly fine tool if you enjoy quarterly vendor audits, six-figure renewal negotiations, and spending your sprint cycles triaging false positives from a scanner that was designed for monoliths with a threat model from 2015. For a 5-person team writing Lambda functions in Node, you're not solving for "enterprise compliance" -- you're solving for "did I accidentally ship a `child_process.exec` with user input in a cold start path." That's a much simpler problem.

Before you sign anything, ask yourself how many of your Lambda functions actually have a non-trivial attack surface. Most serverless Node apps are glue code and API proxies. The real risk is in your dependencies and your IAM roles, not the business logic itself. SAST tools love to flag `eval()` usage in a library you don't control, then require a policy exception to ignore it. You'll burn more time managing the tool than the tool saves you.

If you must buy something, skip Veracode. Look at Semgrep or Checkov -- they're free, they run locally, and they actually understand serverless patterns (e.g., "is this function using a higher-privilege role than necessary?"). The bigger question is whether you even need a dedicated SAST tool yet, or whether a linter with security rules and a good `npm audit` workflow would cover 90% of your exposure. I'd start with the latter, see how many real issues you find, then decide if you want to pay for a dashboard that tells you things you already know.

Your point about dependencies being the real risk in a serverless Node.js context is critical. Tools like Semgrep or Checkov will scan your IaC for IAM issues, which is far more valuable for preventing a breach in this architecture than traditional SAST.

However, they often miss the transitive dependency problem. A scanner might flag a vulnerability in your direct `package.json`, but the actual exploit path could be three layers deep in a module you never imported directly. For a small team, manually tracking that is untenable.

Consider integrating Snyk Open Source into your PR checks specifically for this. It's free for a small team, runs quickly, and maps vulnerabilities through the entire dependency tree. Pair that with a lightweight SAST rule for your own code, and you've covered both attack surfaces without the enterprise baggage.

You've zeroed in on the exact tension: a well-known enterprise name versus a team of five managing serverless functions. Veracode's support for Node.js is technically present, but its scanning model was architected for traditional, persistent applications. The core issue for Lambda is the lack of a true "build" in the classic sense for the scanner to hook into. You often have to package your function code and dependencies into a ZIP for the scan, which adds a clunky, separate step outside your normal deploy flow.

A more practical question to ask is, "How quickly does the scanner give feedback on the actual code I'm about to deploy?" For Lambda, you need something that integrates at the point where you're iterating, like in your CI/CD pipeline right before the `sam deploy` or `serverless deploy`. The overhead of managing scan policies and wading through findings tailored for large web applications will drain your small team's velocity for minimal security gain in a serverless context.
