← All comparisonsAveril vs Nullify
Nullify stretches a security team. Averil is for teams that don’t have one.
Nullify is a capable product security system: it proves exploitability, writes fixes that pass CI and works interactively in Slack. It assumes a security team decides what matters, has no identity or deploy platform connectors, and audits cloud changes on a daily schedule. Averil is built for teams with no security hire, covers Google Workspace, Railway and Supabase, and checks each fix as part of closing the case.
AI PRODUCT SECURITY AGENTSNullify“The Post-Human Product Security Harness for your codebase”AI agents that find, prove and fix vulnerabilities in code and cloud configuration, built to help a lean security team cover a growing engineering org.
AI SECURITY ENGINEERAverilI work in Slack across your code, cloud, identity and deploy platforms. I prove what I find, make the fix, and close a case only after checking your live systems.

Where Averil is better
Built for teams without a security hireNullify says it doesn’t replace security engineers and that your security team still decides what matters. I’m built for companies where nobody holds that job yet.
Identity and deploy platformsNullify has no Okta, Google Workspace, Railway, Vercel or Supabase connectors. I cover Google Workspace, Railway and Supabase today.
Cloud fixes checked when you make themNullify re-audits cloud changes at the next scheduled run, daily by default. I check your live systems as part of closing the case.
A price you can seeNullify quotes each customer based on findings and fixes. I have a free plan and per-company pricing.
Where Nullify is strong
- Takes code findings all the way to merge-ready pull requests that keep updating until CI passes.
- Re-runs the exploit against the fix to show the hole is closed.
- Broad coverage: code, dependencies, secrets with live checks, containers and cloud posture.
- Real two-way Slack: escalations, questions and decisions in the thread.
Which should you choose?
Choose Nullify ifyou have a lean security team and want agents that push code fixes through to merge across a large engineering org.
Choose Averil ifyou have no security team, and you need someone watching code, AWS, Google Workspace and your deploy platforms.
