Key features	Autonomous vulnerability detection, triage, and merge-ready autofix pull requests Direct GitHub and Slack integration for repository assessment Unlimited repositories and users on the Pro tier rather than seat-based limits Pull-request-level review built into existing developer workflows Enterprise tier with SSO and advanced integration support	Automated patching across apps, OS and third-party software Patchless protection mitigating vulnerabilities before patching Script-based remediation where no packaged fix exists Remediation-first rather than scan-and-report Real-time vulnerability visibility
Pros	Moves past detection-only scanning by opening autofix pull requests directly Unlimited repositories and users on Pro avoids per-seat cost creep as teams grow Backed by recognized security and deep-tech investors (Two Sigma Ventures, Root Ventures)	Patchless protection covers the window where exploitation happens Third-party software coverage is where patching usually fails Closes the loop instead of producing another report
Cons	No free tier, so evaluating the product means committing to the $800/year Pro plan Autonomous autofix still needs review before merge on higher-risk codebases Founded in 2022, with a shorter track record than legacy AppSec vendors	Patchless mitigation is a stopgap, not a substitute for patching Enterprise pricing not published
Company	Nullify, founded 2022
