What is the difference between Harness and GitHub Advanced Security (GHAS)?

GHAS is a set of three GitHub-native scanning tools (SAST via CodeQL, SCA via Dependabot, and secret scanning) tightly integrated with GitHub repositories. Harness Security is a full-lifecycle DevSecOps platform that includes SAST, SCA, API security testing, WAAP (Web Application and API Protection), supply chain security, AI security, and Application Security Posture Management (ASPM) — and works across GitHub, GitLab, Bitbucket, Azure DevOps, and more.

Does GHAS work with GitLab, Bitbucket, or Azure DevOps — or only GitHub?

GHAS is primarily designed for GitHub repositories, though a limited version exists for Azure DevOps. It does not natively support GitLab or Bitbucket. Harness Security is SCM-agnostic — working across GitHub, GitLab, Bitbucket, Azure DevOps, and Harness Code — making it the stronger choice for teams using multiple source code platforms or those not fully committed to GitHub.

How does Harness SAST compare to CodeQL?

CodeQL is a powerful, query-based SAST engine supporting around 10 languages, deeply integrated with GitHub. Harness SAST (powered by the acquired Qwiet AI engine) uses a patented Code Property Graph (CPG) approach with reachability analysis — tracing actual data flows to surface only exploitable vulnerabilities, reducing the false positives that CodeQL can generate. Harness SAST also integrates into CI/CD pipelines across any SCM as a pre-configured pipeline step.

What security capabilities does Harness offer that GHAS does not?

Harness offers several capabilities GHAS lacks natively: API DAST (deep testing of REST, GraphQL, and gRPC APIs), Supply Chain Security (protecting pipelines and artifacts), WAAP (runtime attack detection and blocking), AI Security (discovery, testing, and firewall for AI/LLM applications), Secure AI Coding (scanning code from Cursor, Windsurf, Claude Code at the moment of generation), full ASPM with 50+ scanner integrations, and multi-SCM support beyond GitHub.

Does Harness Security support AI-generated code and AI application security?

Yes. Harness launched two dedicated AI security capabilities in early 2026: Secure AI Coding, which scans code generated by AI coding assistants (Cursor, Windsurf, Claude Code) at the moment of generation using its Code Property Graph engine; and AI Security, which includes AI Discovery (inventories your AI attack surface including LLM API calls), AI Testing (probes LLMs for prompt injection, jailbreaks, and data leakage), and AI Firewall (runtime protection against OWASP Top 10 for LLM Applications). GHAS does not have equivalent native capabilities for AI-generated code or LLM/AI application protection.

Can I use Harness Security alongside GHAS, or does it replace it?

Both. Harness STO natively integrates with GHAS — it ingests CodeQL SAST results, Dependabot SCA findings, and GHAS secret scanning results, normalizing and deduplicating them alongside results from 50+ other scanners in the Harness unified dashboard. For teams already invested in GHAS, Harness extends coverage into DAST, API security, WAAP, AI security, and orchestration without a rip-and-replace migration.

How is GHAS priced in 2025–2026, and how does it compare to Harness?

As of April 1, 2025, GitHub unbundled GHAS into two products: GitHub Secret Protection at $19/month per active committer (secrets scanning, push protection) and GitHub Code Security at $30/month per active committer (CodeQL SAST, Dependabot premium, Copilot Autofix). Both require a GitHub Team or Enterprise plan. Because GHAS lacks API DAST, WAAP, and orchestration natively, organizations often need additional tools — increasing total cost of ownership. Harness Security pricing is consumption-based; contact Harness for current rates.

How does Harness reduce false positives compared to GHAS?

Harness uses reachability analysis — both static and runtime — powered by its Code Property Graph (CPG) to determine whether a vulnerable code path is actually exploitable in your specific application. GHAS/CodeQL can produce false positives, particularly in SCA where Dependabot historically flagged vulnerable dependency versions even when the vulnerable function was never called. Harness STO also applies automatic deduplication and normalization across all scanner results to reduce noise further.

What is ASPM, and does GHAS have an equivalent?

Application Security Posture Management (ASPM) aggregates, deduplicates, normalizes, and correlates findings from multiple security scanners into a single unified view — then applies policy and prioritization across all of them. Harness STO functions as a full ASPM, supporting 50+ scanner integrations including ingesting results from GHAS itself. GHAS has a Security Overview dashboard, but it only aggregates findings from its own native tools (CodeQL, Dependabot, secret scanning) and does not function as a cross-tool orchestration layer.

How does Harness SCA compare to Dependabot?

Dependabot flags vulnerabilities based primarily on package version numbers, which can generate false positives when your code doesn't actually call the vulnerable function in a dependency. Harness SCA uses reachability analysis to determine whether vulnerable dependency code paths are actually executed in your application, surfacing only actionable findings. Harness SCA also integrates findings into a unified dashboard alongside SAST, container, and secrets results — whereas Dependabot findings are siloed within GitHub's interface.

When should I choose GHAS over Harness?

GHAS is the stronger choice when: your engineering organization is 100% standardized on GitHub with no plans to use other SCMs; your primary security needs are SAST (CodeQL), dependency management (Dependabot), and secrets detection; your security team is small and you want the lowest-friction, GitHub-native experience without managing a separate platform; or you're a startup or smaller team where API DAST, SCS, WAAP, and AI security aren't yet priorities. Harness is the better fit when you need comprehensive SDLC coverage including API DAST, supply chain security, runtime protection, AI security, or multi-SCM support — or when you need enterprise-grade orchestration across multiple security tools and teams.

What compliance frameworks does Harness Security support vs. GHAS?

Harness supports compliance reporting and policy enforcement aligned to SOC 2, PCI DSS, HIPAA, NIST SSDF, SLSA, and FedRAMP-adjacent requirements, with audit trails, policy-as-code via OPA, and SBOM generation. GHAS provides security insights within GitHub's Security Overview with some compliance mapping, but does not offer the same breadth of policy enforcement, SBOM generation, or framework-specific compliance reporting that Harness provides for regulated industries.

Does GHAS include DAST (Dynamic Application Security Testing)?

No. GHAS does not include native DAST. GitHub itself recommends integrating third-party DAST tools via GitHub Actions to fill this gap. Harness includes native API DAST as part of its platform, testing running APIs for runtime vulnerabilities like authentication failures, injection attacks, and misconfigurations.

Is Harness Security available for GitHub Actions?

Yes. Harness integrates natively with GitHub Actions, so teams already using GitHub don't need to abandon their existing CI/CD workflows to adopt Harness. Harness pipeline steps can run directly inside GitHub Actions workflows, ingesting results from native GHAS tools (CodeQL, Dependabot, secret scanning) alongside Harness-native and third-party scanners, and surfacing everything in the unified Harness dashboard. This means you can add Harness capabilities — API DAST, supply chain security, WAAP, AI security, and cross-tool orchestration — incrementally on top of your existing GitHub Actions investment without a rip-and-replace migration.

What is WAAP and does GHAS include it?

Web Application and API Protection (WAAP) is a runtime security capability that monitors live application and API traffic, detecting and blocking attacks in real time — covering the OWASP Top 10, bot attacks, DDoS, API abuse, and more. It goes beyond code scanning to protect applications after they're deployed. Harness includes WAAP as part of its platform (via its Traceable acquisition). GHAS does not include WAAP; it is focused on pre-production scanning and does not extend to runtime protection.

Does GHAS support supply chain security? How does Harness Supply Chain Security (SCS) compare?

GHAS addresses supply chain security primarily through Dependabot (dependency vulnerability alerts and automated PRs) and Dependency Review (blocking vulnerable dependencies in PRs). Harness SCA scans container images as well as open source packages, while Supply Chain Security (SCS) generates (or ingests) SBOMs, signs and verifies artifacts, ensures pipeline integrity, and verifies SLSA framework compliance — providing a broader and more comprehensive approach to securing the software supply chain from code to deployment.

Does GHAS include container and IaC security? How does Harness compare?

GHAS does not include native container image scanning. For Infrastructure as Code (IaC), GHAS announced AI-powered detections for Terraform, Dockerfile, Shell/Bash, and PHP in March 2026, entering public preview in Q2 2026 — this is a meaningful expansion but is still preview-quality and limited to detection within pull requests. GitHub continues to recommend third-party tools for container scanning. Harness STO natively supports container scanning and IaC scanning as built-in pipeline steps, with pre-configured integrations for tools like Aqua Trivy, alongside its own native scanners — all feeding into the unified Harness dashboard.

How does each platform handle vulnerability prioritization?

Harness prioritizes vulnerabilities using a multi-signal approach combining CVSS scores, EPSS (Exploit Prediction Scoring System) scores, static reachability analysis, and runtime reachability — focusing developer effort on vulnerabilities that are both severe and actually exploitable in your specific environment. GHAS/Dependabot has added EPSS scores for dependency alerts, and CodeQL provides severity ratings, but lacks the cross-tool, cross-signal prioritization that Harness STO provides across all scanner types in a single view.

We're all-in on GitHub. Should we still consider Harness Security?

Yes, for two reasons. First, GHAS has significant coverage gaps (no native API DAST, no supply chain security, no WAAP, no AI security, no multi-scanner orchestration) that require additional tools regardless of your SCM commitment. Second, Harness integrates natively with GitHub — it can run inside your existing GitHub Actions workflows, ingest GHAS scan results, and add orchestration, API DAST, supply chain security, and runtime protection on top of your existing investment. You get the benefits of GitHub's native developer experience plus a complete AppSec program.

How does Harness Security handle multi-team and enterprise scale?

Harness STO is built for enterprise scale — it can standardize a pre-approved set of security controls and deploy them across thousands of pipelines in a single operation. Pipeline-level policies enforce security gates across multiple stages, tools, and teams simultaneously. Role-based access control (RBAC) enables separate permissions for developers and security teams. GHAS scales well within GitHub's repository model, but permission customization is more limited, and cross-team policy enforcement requires GitHub Actions configuration at scale.

What is the total cost of ownership (TCO) of GHAS vs. Harness Security?

GHAS's per-committer pricing ($19–$30/month on GitHub.com, or $49/month on Azure DevOps) can appear straightforward, but TCO increases significantly when accounting for the additional tools required to fill native gaps: a DAST tool, an API security testing platform, a WAAP solution, a container scanner, an IaC scanner, and a cross-tool orchestration layer. Harness Application Security Testing consolidates SAST, SCA, DAST, API security, WAAP, supply chain security, container scanning, secrets detection, AI security, and orchestration in a single platform — reducing tool sprawl, integration overhead, and the operational cost of managing multiple vendor relationships.

Key Differentiators

Where Harness Goes Further Than GHAS

Harness

GitHub Advanced Security

GHAS gives you three tools. Harness gives you a complete AppSec platform.

Harness

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

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

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.

GitHub Advanced Security

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

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

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

You're 100% GitHub-native and plan to stay that way
SAST, secrets scanning, and SCA are your only security requirements

Harness vs

Kargo

The Argo community, including Argo's own creators at Akuity, recognized this and built Kargo to fill the gap. Kargo adds real promotion orchestration on top of Argo CD, and its PR-based promotion model is a genuinely good GitOps pattern. But particularly as teams scale, Kargo doesn't close the rest of the gap well: it's Kubernetes-only outside a paid tier, has no policy-as-code engine, supports just a single manual approval step, and its verification is simple threshold checks with no AI behind it. That's where Harness comes in. Harness works with Argo CD directly, no Kargo required, and adds the promotion orchestration, governance, and AI-driven verification enterprises need once GitOps scales beyond a single team's cluster.
