GitHub Advanced Security is three GitHub-native scanning tools. Harness AST is a full-lifecycle DevSecOps platform spanning SAST, SCA, supply chain, API, runtime, and AI security — across any SCM.
Feature Comparison
| Feature | Harness | Competitor |
|---|---|---|
| Application Security Testing (AST) | ||
| SAST (Static Application Security Testing) | Supports all top SCM vendors — GitHub, GitLab, Bitbucket, Azure, etc. | Only supports GitHub and Azure Repos; requires a 3rd-party tool for other repos |
| Secrets detection | Supports all top SCM vendors — GitHub, GitLab, Bitbucket, Azure, etc. | Only supports GitHub and Azure Repos; requires a 3rd-party tool for other repos |
| SCA (Software Composition Analysis) | Supports all top SCM vendors — GitHub, GitLab, Bitbucket, Azure, etc. | Only supports GitHub and Azure Repos; requires a 3rd-party tool for other repos |
| AI-powered fix suggestions | Leverages CPG to fix exploitable vulnerabilities | Copilot Autofix for PRs; Dependabot alerts handed to coding agents for PRs |
| Vulnerability prioritization | CVSS, EPSS, and static reachability | CVSS, EPSS only; no static reachability |
| Container security | Native scanning + pre-built 3rd-party integrations (Aqua Trivy, etc.) | No native capability; requires a 3rd-party tool via GitHub Actions |
| DAST (Dynamic Application Security Testing) | Native API and AI testing with replayed production traffic; no web DAST | No dynamic testing capability; requires a 3rd-party tool |
| IaC security | Native Terraform support + pre-built 3rd-party IaC tool integrations | Preview only — Terraform, Dockerfile, Shell/Bash, PHP (Q2 2026); no GA |
| Orchestration | 50+ Harness and 3rd-party scanner integrations | Only CodeQL, Dependabot, and Secret Scanning |
| Policy & governance | Pipeline-level OPA policy engine purpose-built for security governance | Requires writing and maintaining custom YAML |
| Supply Chain Security | ||
| SBOM generation & policy enforcement | Generate, import 3rd-party SBOMs, and enforce policy via OPA | Generate, import 3rd-party SBOMs, and enforce policy |
| Artifact signing & verification | Cosign-based signing and verification with Chain of Custody UI | Sigstore-based signing and verification; no Chain of Custody UI |
| Pipeline integrity checks | CIS and OWASP Top 10 CI/CD Risks coverage | OIDC credential management and deployment approval gates |
| SLSA compliance | Build Levels 1, 2, and 3 as native pipeline steps | Design / enforce your own secure build environment for Level 3 |
| Securing AI | ||
| In-IDE AI code scanning | Scans code from Cursor, Windsurf, and Claude Code at code generation | Limited scanning at generation via Copilot; all others at commit/PR |
| AI discovery | Auto-discovers LLMs, MCP servers, and agents in production environments | Not a runtime solution; no AI component discovery capability |
| AI testing | Dynamically tests AI components against OWASP Top 10 LLM threats | Not a runtime solution; no AI application testing |
| AI firewall | Runtime protection for AI-native apps against OWASP Top 10 LLM threats | Not a runtime solution; no AI-specific runtime protection |
| Runtime Security (WAAP) | ||
| WAF (Web Application Firewall) | API-centric WAF with unified code-to-runtime vulnerability visibility | Not a runtime solution; no WAF capability |
| API security | Discover, test, and protect production APIs with code-to-runtime visibility | Not a runtime solution; no API security capability |
| Bot protection | Comprehensive bot detection capabilities | Not a runtime solution; no bot protection |
| Abuse protection | API data lake-powered protection against business logic abuse | Not a runtime solution; no abuse protection |
Key Differentiators
Where Harness Goes Further Than GHAS
GHAS gives you three tools. Harness gives you a complete AppSec platform.
Harness delivers SAST, SCA, secrets detection, API and AI DAST, container security, IaC scanning, and runtime security all on a single platform - designed to work together, not stitched together, with static reachability to help you prioritize fixing what matters first.
GitHub Advanced Security includes three tools - CodeQL, Dependabot, and Secret Scanning - deeply integrated with GitHub repositories and developer workflows. It's a good starting point for GitHub-native teams if all you need is SAST, SCA, and secrets detection.
Harness catches AI-generated vulnerabilities before GHAS starts scanning.
Harness scans AI-generated code at the moment it's generated — identifying vulnerabilities before they reach a commit or PR. It works across Cursor, Windsurf, and Claude Code, not just those inside the GitHub ecosystem.
GHAS mostly scans code at commit or PR time. This works well for traditionally written code, but can't keep up with AI coding workflows. It offers limited scanning at the moment of generation only for Copilot, not other AI tools.
GHAS only works where GitHub works. Harness works everywhere.
Harness works across GitHub, GitLab, Bitbucket, Azure Repos, Harness Code, and more - applying consistent SAST, SCA, secrets detection, and pipeline security controls regardless of which or how many SCMs your teams use.
GitHub Advanced Security is built for GitHub repositories. A limited extension exists for Azure DevOps, but not GitLab, Bitbucket, or other SCMs. Teams using multiple source code platforms will need additional tooling to fill the gaps.
Decision Guide
Competitor is good for
- You're 100% GitHub-native and plan to stay that way
- SAST, secrets scanning, and SCA are your only security requirements
- Your only AI coding tool is Copilot.
- You want security bundled into your existing GitHub Enterprise license with zero additional vendors
- Your threat model stops at the repository.
Harness is best for
- You use GitHub, GitLab, Bitbucket, or a mix of SCMs
- You need supply chain security, API security, runtime protection, or AI security
- Your developers use Cursor, Windsurf, Claude Code, or other AI coding agents
- You want a complete AppSec platform without stitching tools together
- Your threat model extends into CI/CD pipelines and production
Summary
SAST, secrets scanning, and SCA are a start, not a strategy.
