How Nullify and GitHub Advanced Security compare

Twelve capabilities, grouped by what your program needs: finding risk, proving and fixing it, and buying and running the tool.

CodeQL code scanningFree on public repos; third-party SARIF upload.
✓
16 languagesTraces untrusted input through real code paths to catch business-logic flaws such as IDOR.
SCA / dependencies
✓
DependabotAlerts and update PRs; dependency review on merge.
✓
17 ecosystemsReachability plus infrastructure exposure.
Container / IaC
×

Secrets detection
✓
Secret scanningWith push protection and validity checks, a genuinely strong story.
✓
Live credential verificationWith suspected owner and a rotation workflow.
DAST / pentesting
×

✓
Agent-driven pentestsMulti-stage exploitation of REST and GraphQL APIs; broader surfaces via Bug Hunts.
Cloud security
×
Not offeredNot part of the product scope.
✓
AWS, GCP, Azure and Kubernetes auditsCorrelated to owning repos, plus external attack-surface scanning.
Proving and fixing risk
Exploitability validation
×
Not offeredCode alerts are left to your team's triage; validity checks exist for leaked secrets only.
✓
Reproducible exploit proofBefore a finding surfaces.
Automated remediation
–
LimitedCopilot Autofix suggestions require explicit developer review and acceptance (GitHub reports fixes more than three times faster than manual); Dependabot auto-PRs cover dependencies.
✓
89% merge-readyFixes validated against your build before the PR opens, then managed to merge with self-healing fixes when CI fails.
Business-context prioritization
×
Not offeredSecurity overview reports risk distribution; prioritization is human-driven.
✓
VaultScores impact against your real assets, data sensitivity and threat model.
Autonomous operation
×
Not offeredAssistive by design; developers accept, edit or dismiss every suggestion.
✓
Detect → validate → fix → mergeThe program runs end to end; humans set guardrails and approve merges.

4 Areas Where Nullify Goes
Further Than GitHub Advanced Security

Proof, not alerts
Nullify

Every in-scope finding is exploited before it's reported, with request/response pairs, screenshots and video, then re-reviewed against its own evidence.

GGitHub Advanced Security

CodeQL, secret scanning and Dependabot find issues in GitHub repositories. Findings aren't exploited to confirm they're real.

Impact scored to your business
Nullify

Vault scores impact against your environment: internet reachability from cloud context, source-to-sink flow from code, and data sensitivity and policy from your docs.

GGitHub Advanced Security

Alerts carry CVSS and dependency severity. Impact isn't scored against your cloud exposure or business context.

Fixes that actually merge
Nullify

Fixes are validated against your build and tests before the PR opens. If CI fails, Nullify reads the logs and pushes follow-up commits until it's merge-ready.

GGitHub Advanced Security

Copilot Autofix suggests fixes on code scanning alerts, and Dependabot opens upgrade PRs.

Work that reaches closure
Nullify

Campaigns route each fix to the owner with review capacity, follow up on stale PRs and escalate in Slack before an SLA slips.

GGitHub Advanced Security

Security campaigns help organize the work. Following up and escalating remain manual.

Based on publicly available product information, November 2026.

Pricing

Per committer vs. per outcome

GitHub Advanced Security

Per active committer

GitHub sells Advanced Security as two standalone products, available since April 1, 2025.

  • Code Security: $30 per active committer per month
  • Secret Protection: $19 per active committer per month

Nullify

Outcome-based

Priced against the security work Nullify performs, not per seat or per license tier.

  • We scope what your program needs, estimate the volume of work, and price against that, so cost tracks the outcomes you get.
