A side-by-side comparison of Semgrep vs. Nullify AI. Easily compare performance across multiple categories.
| Capability | Nullify AI | Semgrep |
|---|---|---|
| SAST / code scanning | ✓ 16 languages; traces untrusted input through real code paths to catch business-logic flaws such as IDOR | ✓ 35+ languages; transparent rules, cross-file Pro Engine, multimodal AI detection (Semgrep cites up to 3.5x more true positives than AI alone) |
| SCA / dependencies | ✓ 17 ecosystems; reachability plus infrastructure exposure | ✓ Reachability-first supply chain analysis; upgrade PRs with breaking-change flags |
| Container / IaC | ✓ Container image review and IaC scanning (Terraform, CloudFormation, Kubernetes manifests) | Not documented on Semgrep's public pages |
| Secrets detection | ✓ Live credential verification, suspected owner and rotation workflow | ✓ Semantic detection with locally-run credential validators |
| DAST / pentesting | ✓ Agent-driven pentests with multi-stage exploitation (REST and GraphQL APIs; broader surfaces via Bug Hunts) | – No DAST or pentesting product |
| Cloud security | ✓ AWS, GCP, Azure and Kubernetes audits, correlated to owning repos; plus external attack-surface scanning | – No cloud posture product; code security only |
| Exploitability validation | ✓ Reproducible exploit proof before a finding surfaces | Limited — Assistant predicts true/false positives with reachability and EPSS; no exploitation |
| 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 — remediation guidance in PR comments; code-changing Autofix in beta; dependency upgrade PRs |
| Business-context prioritization | ✓ Vault scores impact against your real assets, data sensitivity and threat model | Limited — component tagging and reachability/EPSS filtering; code-derived context |
| Autonomous operation | ✓ The program runs detect → validate → fix → merge end to end; humans set guardrails and approve merges | Limited — Assistant auto-handles much of triage, but the model is explicitly human-in-the-loop |
| Pricing model | Outcome-based — priced against the security work performed, not per seat (direct or via AWS Marketplace) | Public — Free (up to 10 contributors and 10 repositories); Teams from $30/mo per contributor per product (Secrets $15); Enterprise by quote |
| 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 | Hybrid — scans run in your CI with a cloud control plane; managed scans in beta |
Semgrep publishes tiered, per-contributor pricing.
Nullify is priced against the security work it performs, not per seat or per license tier.
