Github Security Scanner Alternative
That Secures More Than Your Code
GitHub Advanced Security (GHAS) stops at the repo.
Checkmarx protects the full software supply chain, helping teams deliver secure code at scale.
The Agentic Appsec Platform That Secures Code;
Not the One That Writes It
GHAS is a convenient GitHub-native security feature. Checkmarx is the enterprise-grade, multi-SCM solution that secures every line of code; wherever it lives.
Real SAST & SCA, Not Lightweight Bundle
GHAS gives you CodeQL plus Dependabot plus Secret Scanning — useful, but not a full AppSec platform. Checkmarx delivers enterprise-grade SAST with customizable queries and SCA with the industry’s largest malicious package database (420k+ identified). It’s the difference between a feature and a product line.
Trusted AI for Real Application Security
Ensure accountability with explainable AI that identifies vulnerabilities and validates every fix; never guesswork or unreviewed code generation. GHAS Copilot Autofix optimizes for code velocity, not security accuracy or audit trail.
Works Across Every Repo, Not Just GitHub
Most enterprises don’t run on a single SCM. Checkmarx integrates natively with GitHub, GitLab, Bitbucket, Azure DevOps, and self-hosted Git – with consistent results, policy, and reporting across all of them. GHAS only protects what’s in GitHub.
Complete Code-to-Cloud Coverage
GHAS covers code scanning and dependency review. That’s it. Checkmarx One adds SCA with malicious package detection, IaC scanning (KICS), API security, container security, ASPM, and supply chain protection – all correlated in one platform.
Code Scanning Alerts Built for Developers
GHAS alerts often lack the context developers need to act. Checkmarx provides best-fix-location guidance, exploitable path analysis, and just-in-time training so developers know exactly what to do, where, and why – in any IDE, in any pull request.
Governance That Doesn’t Get in the Way
Enterprise AppSec needs policy, exceptions, separation of duties, and audit trails – without breaking developer flow. Checkmarx ASPM gives security teams real governance across every repo and engine. GHAS governance is limited to GitHub-hosted code.
Checkmarx vs. GitHub: full breakdown
| Capability | Checkmarx One | GitHub Advanced Security |
|---|---|---|
| AppSec Expertise | ✓ WIN 20+ year AppSec leader; named in Gartner MQ for AST every year since the category began | DevOps platform that bolted on security via the CodeQL acquisition. Still organized around GitHub-native workflows |
| Platform | ✓ WIN Unified platform: SAST, SCA, IaC, API, Container, Malicious Packages, ASPM, AI Supply Chain Security | Code Scanning + Dependency Review + Secret Scanning bundled inside GitHub. No native DAST/IaC/SSCS/Container Security Solutions. |
| Checkmarx SAST vs CodeQL |
✓ WIN
Hybrid Deterministic and LLM-based engines. Customizable queries, exploitable path analysis, best-fix-location guidance, all languages. Safe refactor accuracy. |
CodeQL is a single, deterministic engine, with limited customization and language support; tuning often requires writing CodeQL queries in-house. Detection bound to CodeQL’s rule set and language coverage. |
| Checkmarx SCA + Malicious Packages vs Dependabot | ✓ WIN Full SCA with malicious package detection (420k+ identified), exploitable path, supply chain protection, SBOM | Dependabot for vulnerable dependencies; no malicious package detection. Limited reachability context. |
| Accuracy |
✓ WIN
Highest fidelity with an F1 score of 0.64 vs industry average of ~ 0.20. This reflects highest accuracy and recall. Tuned presets out of the box, customizable queries, exploitable path to cut noise. |
Customers report tuning CodeQL to enterprise stacks is non-trivial |
| AI Remediation | ✓ WIN Triage & Remediation Assist scores reachability and exploitability (Attackability) before proposing a fix, then opens a merge-ready pull request | Agentic Autofix / Copilot Autofix (public preview only) assigns alerts to a cloud agent that explores the codebase and proposes a fix — no reachability/exploitability gate before the agent acts, and usage draws down paid AI Credits. |
| Checkmarx SCA + Malicious Packages vs Dependabot | ✓ WIN Full SCA with malicious package detection (500K+ identified), exploitable path, supply chain protection, full SBOM support | Dependabot for vulnerable dependencies; no malicious package detection. Limited reachability context. |
| SCM Coverage | ✓ WIN Native integrations across GitHub, GitLab, Bitbucket, Azure DevOps, and self-hosted Git | GitHub-only by design. A limited private preview of Copilot Autofix for GitHub Advanced Security for Azure DevOps is rolling out but is not broadly available. |
| Developer Experience | Native IDE plugins, PR feedback, just-in-time training, AI remediation in any SCM | GitHub-native UX – if 100% of work is in GitHub. Findings appear post-commit inside GitHub’s own workflow. |
| AI Security | ✓ WIN Employs trusted, explainable AI to secure AI-generated code, build custom queries, and verify LLM output for safe remediation. | Copilot Autofix focuses on code generation; less rigor on security policy and traceability. Lack explainable validation. |
| AI Explainability & Separation of Duties | ✓ WIN Clear separation between dev suggestions and security findings; explainable AI that verifies and secures every fix. | Fix suggestions and code generation share the same agent surface, creating risk if AI-generated patches are insecure. |
| IaC & Container Security | ✓ WIN Industry-leading KICS (4M+ downloads, 20+ languages) plus native container scanning, correlated with SAST results | Not natively offered as part of GHAS |
| API Security | ✓ WIN Complete API discovery, risk detection, shift-left testing as a first-class engine | Not offered |
| Support | ✓ WIN Dedicated AppSec technical account management and premium services | GitHub general support; AppSec-specific expertise varies |
| Enterprise Visibility & Governance | ✓ WIN ASPM, policy engine, separation of duties, exceptions, audit trail across every repo, AI-BOM and SBOM | Enterprise security overview limited to GitHub-hosted repos. |
