Feature by feature

How Nullify and Endor Labs compare

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

Capability

Finding risk

SAST / code scanning

✓

AI SASTAgentic reasoning plus deterministic analysis, 40+ languages.

✓

16 languagesTraces untrusted input through real code paths to catch business-logic flaws such as IDOR.

SCA / dependencies

✓

Function-level reachabilityThe flagship, across direct and transitive dependencies; Endor cites a 97% reduction in non-actionable alerts.

✓

17 ecosystemsReachability plus infrastructure exposure.

Container / IaC

✓

Container scanningPlus malware protection for open-source dependencies.

✓

Container image review and IaC scanningTerraform, CloudFormation, Kubernetes manifests.

Secrets detection

✓

Credential identification and validationBundled with AI SAST.

✓

Live credential verificationWith suspected owner and a rotation workflow.

DAST / pentesting

Not offeredNo DAST, pentesting or runtime testing product.

✓

Agent-driven pentestsMulti-stage exploitation of REST and GraphQL APIs; broader surfaces via Bug Hunts.

Cloud security

Not offeredNo cloud posture product (RSPM covers repository posture, not cloud).

✓

AWS, GCP, Azure and Kubernetes auditsCorrelated to owning repos, plus external attack-surface scanning.

Proving and fixing risk

Exploitability validation

✓

Deterministic static evidenceCall-path proof and dataflow validation; no runtime exploit replay.

✓

Reproducible exploit proofUnder real-world conditions.

Automated remediation

✓

Remediation PRs and Endor PatchesBackported patches and Upgrade Impact Analysis; fixes delivered for developer approval.

✓

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

–

LimitedReachability and code context; no business-asset or data-sensitivity model evidenced.

✓

VaultScores impact against your real assets, data sensitivity and threat model.

Autonomous operation

–

LimitedAn intelligence layer that equips your developers and coding agents; assist-and-approve by design.

✓

Detect → validate → fix → mergeThe program runs end to end; humans set guardrails and approve merges.

Buying and running it

Pricing model

No public price listFree developer tier; paid Core and Pro editions by quote.

Outcome-basedPriced against the security work performed, not per seat. Direct or via AWS Marketplace.

Deployment

◇

SaaSIntegrates with GitHub, GitLab, Bitbucket and CI systems; on-premises Outpost deployment on request.

◇

Dedicated enterprise tenant (SaaS)SCM-agnostic: GitHub, GitLab, Bitbucket or Azure DevOps with scoped, least-privilege access. No self-hosted option documented.

4 Areas Where Nullify Goes
Further Than Endor Labs

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.

EEndor Labs

Built around reachability analysis for open-source dependencies, with SAST alongside. Findings aren't exploited to prove 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.

EEndor Labs

Function-level reachability narrows which dependency issues matter. Business context comes from the policies you configure.

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.

EEndor Labs

Upgrade impact analysis helps plan dependency upgrades your developers 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.

EEndor Labs

Policies and ticketing integrations flag the work. The last mile to merge is yours to run.

Endor Labs

Free tier, then by quote

Endor Labs does not publish a price list.

Developer: free
Core and Pro editions: paid tiers for teams, priced by quote
