A side-by-side comparison of GitHub Advanced Security vs. Nullify AI. Easily compare performance across multiple categories.
| Capability | Nullify AI | GitHub Advanced Security |
|---|---|---|
| SAST / code scanning | ✓ 16 languages; traces untrusted input through real code paths to catch business-logic flaws such as IDOR | ✓ CodeQL code scanning; free on public repos; third-party SARIF upload |
| SCA / dependencies | ✓ 17 ecosystems; reachability plus infrastructure exposure | ✓ Dependabot alerts and update PRs; dependency review on merge |
| Container / IaC | ✓ Container image review and IaC scanning (Terraform, CloudFormation, Kubernetes manifests) | Not documented on GitHub's public pages |
| Secrets detection | ✓ Live credential verification, suspected owner and rotation workflow | ✓ Secret scanning with push protection and validity checks — a genuinely strong story |
| DAST / pentesting | ✓ Agent-driven pentests with multi-stage exploitation (REST and GraphQL APIs; broader surfaces via Bug Hunts) | – Not part of the product scope |
| Cloud security | ✓ AWS, GCP, Azure and Kubernetes audits, correlated to owning repos; plus external attack-surface scanning | – Not part of the product scope |
| Exploitability validation | ✓ Reproducible exploit proof before a finding surfaces | – Code alerts are left to your team's triage; validity checks exist for leaked secrets only |
| Automated remediation | ✓ Fixes validated against your build before the PR opens, then managed to merge with self-healing fixes when CI fails; 89% merge-ready | Limited — Copilot Autofix suggestions require explicit developer review and acceptance (GitHub reports fixes more than three times faster than manual); Dependabot auto-PRs cover dependencies |
| Business-context prioritization | ✓ Vault scores impact against your real assets, data sensitivity and threat model | – Security overview reports risk distribution; prioritization is human-driven |
| Autonomous operation | ✓ The program runs detect → validate → fix → merge end to end; humans set guardrails and approve merges | – Assistive by design; developers accept, edit or dismiss every suggestion |
| Pricing model | Outcome-based — priced against the security work performed, not per seat (direct or via AWS Marketplace) | Public — two standalone products since April 1, 2025: Code Security $30 and Secret Protection $19 per active committer per month |
| Deployment | Dedicated enterprise tenant (SaaS), SCM-agnostic: installs via GitHub, GitLab, Bitbucket or Azure DevOps with scoped, least-privilege access; no self-hosted option documented | GitHub.com, self-hosted GitHub Enterprise Server, and an Azure DevOps add-on |
GitHub sells Advanced Security as two standalone products, available since April 1, 2025.
Nullify is priced against the security work it performs, not per seat or per license tier.
