The Fundamental Distinction: Static vs. Runtime
This is not a direct competitor comparison — it's a complementary tools comparison. Snyk and PentestCheck test different things. A mature security program needs both. Understanding which gap each fills helps you build the complete picture.
PentestCheck — Runtime
Tests the live deployed application as an attacker would. Finds vulnerabilities that only exist at runtime: authentication bypass, IDOR, SSRF, misconfigured cloud storage, open ports. Code quality doesn't matter — what matters is what attackers can actually reach and exploit.
EASM → DAST → Runtime Findings
Snyk — Code
Analyzes source code, dependencies, container images, and IaC before deployment. Finds vulnerabilities in the codebase: insecure code patterns, CVE-affected dependencies, misconfigured Dockerfiles. Integrates into IDE and CI, giving developers feedback during development.
SAST → SCA → Code Findings
What Each Misses Without the Other
Snyk alone misses:
- Unknown exposed subdomains and assets
- Runtime IDOR and authorization flaws
- Misconfigured cloud storage (S3, GCS)
- Open ports and exposed services
- SSRF in deployed configuration
PentestCheck alone misses:
- Vulnerable dependencies before deployment
- Insecure code patterns in source
- Container image vulnerabilities
- IaC misconfigurations before apply
- Developer-facing early-stage feedback

Recommendation
Run Snyk in your IDE and CI pipeline to catch code and dependency issues before they ship. Run PentestCheck against your deployed environments to continuously validate what attackers can actually reach. The combination gives you coverage at every layer: code, build, and runtime.
