How Nullify and Semgrep compare

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

Capability
Semgrep
Nullify
Finding risk
SAST / code scanning
✓
35+ languagesTransparent rules, cross-file Pro Engine and multimodal AI detection. Semgrep cites up to 3.5x more true positives than AI alone.
✓
16 languagesTraces untrusted input through real code paths to catch business-logic flaws such as IDOR.
SCA / dependencies
✓
Reachability-first supply chain analysisUpgrade PRs with breaking-change flags.
✓
17 ecosystemsReachability plus infrastructure exposure.
Container / IaC
×
Not documentedNot on Semgrep's public pages.
✓
Container image review and IaC scanningTerraform, CloudFormation, Kubernetes manifests.
Secrets detection
✓
Semantic detectionWith locally run credential validators.
✓
Live credential verificationWith suspected owner and a rotation workflow.
DAST / pentesting
×
Not offeredNo DAST or pentesting product.
✓
Agent-driven pentestsMulti-stage exploitation of REST and GraphQL APIs; broader surfaces via Bug Hunts.
Cloud security
×
Not offeredNo cloud posture product; code security only.
✓
AWS, GCP, Azure and Kubernetes auditsCorrelated to owning repos, plus external attack-surface scanning.
Proving and fixing risk
Exploitability validation
–
LimitedAssistant predicts true/false positives with reachability and EPSS; no exploitation.
✓
Reproducible exploit proofBefore a finding surfaces.
Automated remediation
–
LimitedRemediation guidance in PR comments; code-changing Autofix in beta; dependency upgrade PRs.
✓
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
–
LimitedComponent tagging and reachability/EPSS filtering; code-derived context.
✓
VaultScores impact against your real assets, data sensitivity and threat model.
Autonomous operation
–
LimitedAssistant auto-handles much of triage, but the model is explicitly human-in-the-loop.
✓
Detect → validate → fix → mergeThe program runs end to end; humans set guardrails and approve merges.
Buying and running it
Pricing model

4 Areas Where Nullify Goes
Further Than Semgrep

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.

SSemgrep

Matches code against rules, including custom rules you write, with reachability for dependencies. Findings aren't exploited to confirm them.

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.

SSemgrep

Semgrep Assistant helps triage with AI. Impact isn't scored from your cloud exposure or internal policy docs.

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.

SSemgrep

Assistant suggests autofixes on findings for a developer to review and apply.

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.

SSemgrep

Findings reach developers in PRs and tickets. Driving them to merge is manual.

Based on publicly available product information, November 2026.

Pricing

Per contributor vs. per outcome

Semgrep

Per contributor, per product

Semgrep publishes tiered, per-contributor pricing.

  • Free: up to 10 contributors and 10 repositories
  • Teams: from $30 per month per contributor per product (Code and Supply Chain $30, Secrets $15)
  • Enterprise: custom pricing

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.
