Nullify is an AI-powered AppSec automation platform that finds, prioritizes, and fixes code vulnerabilities with a 90% merge-ready auto-generated fix rate. It replaces manual SAST triage with cloud-reachability analysis that filters out non-exploitable findings before they reach a developer's queue, cutting false-positive review time for small security teams.
About Nullify
Nullify is an AI-powered autonomous security platform founded in 2022 that replaces manual application security engineering with AI agents. The platform automates the full vulnerability lifecycle: continuous detection of secrets, vulnerable code, infrastructure-as-code flaws, container misconfigurations, and dependency issues; autonomous triage using threat intelligence specific to your tech stack; and remediation with patch generation. Its core differentiator is real cloud reachability analysis: unlike traditional SAST tools that flag every potential issue, Nullify checks whether a vulnerability is actually exploitable based on permission boundaries and runtime exposure before it reaches a developer's queue. Backed by $17.8M in funding from SYN Ventures, Two Sigma Ventures, and Black Nova Venture Partners, Nullify has saved customers 48,000+ hours of manual security work and automatically resolved over 450 vulnerabilities to date. It is purpose-built for small-to-mid-sized security teams that lack dedicated AppSec engineers.
Pricing
Pro tier: $800/year, unlimited repositories, users, and detections. Enterprise: custom pricing with API access, SSO, advanced integrations, and dedicated support. No per-developer or per-repository overage charges. Annual commitment required.
Key Features
- Intelligent Vulnerability Detection: AI-driven analysis flags business logic flaws, injection vulnerabilities, authorization bypasses, and container misconfigurations, filtering out non-exploitable findings using cloud reachability and permission analysis.
- Secrets Detection & Validation: Automatically detects hardcoded credentials and API keys in repositories, then validates whether each secret is actually live by testing real access before flagging it.
- Automated Remediation: Generates pull requests with fixes matched to your codebase's error handling and coding style, hitting a 90% developer merge rate without manual rework.
- Threat Intelligence Integration: Tracks actively exploited CVEs and zero-day vulnerabilities affecting your specific dependencies, prioritizing fixes by real-world exploitation likelihood.
- GitHub App Integration: Scans every commit and pull request as a native GitHub App, with two-way Jira Cloud ticket sync and Slack alerting built in.
Pros
- Cloud-reachability filtering means alerts arrive already vetted for real exploitability, cutting the alert-fatigue problem that makes traditional SAST tools easy to ignore.
- Generated patches typically merge without rework because they follow your team's existing error-handling and style conventions rather than generic templates.
- Saves teams real time: customers report roughly 20 hours saved per developer each year, contributing to a reported 48,000+ hours of manual security work eliminated overall.
Cons
- No free tier, and the Pro plan requires an annual commitment, which excludes solo developers and small teams with minimal security budgets; a free tier would accelerate adoption.
- AI tuning takes real calibration time before prioritization matches your specific codebase and organizational context; initial setup is not instant.
- No Azure DevOps, GitLab, Linear, or self-hosted Jira Server support: coverage is GitHub and Jira Cloud only, which limits adoption at enterprises running a mixed or non-GitHub toolchain.

Frequently Asked Questions
What are Nullify's pricing plans in 2026?
The Pro plan is Nullify's only self-serve tier, priced at $800 per year regardless of team size, with unlimited repos and detections included rather than metered per scan. Enterprise pricing is custom and adds single sign-on plus a dedicated API for teams that need to wire Nullify into their own tooling.
Can you use Nullify without paying?
Nullify skips a free tier entirely. Pro is the only self-serve option, priced at $800 a year with unlimited repositories and users included rather than metered per scan. Teams that want to try it first should expect an annual commitment up front instead of a scaled-down trial.
What are Nullify's closest competitors?
Checkmarx One and GitHub Advanced Security offer broader enterprise SAST coverage, but at higher cost and with more configuration overhead. Snyk focuses mainly on dependency and container scanning rather than full-lifecycle detection-to-patch automation. Nullify differentiates with cloud-reachability filtering that determines whether a flaw is actually exploitable before it reaches a developer's queue.
What separates Nullify from Checkmarx?
Checkmarx One provides deeper enterprise SAST and compliance reporting, built for large in-house security teams. Nullify instead automates triage and remediation so a small team can act without hiring extra staff, generating patches that match existing coding conventions. Checkmarx suits organizations that already run a dedicated AppSec function; Nullify suits teams that do not.
How long does it take to get going with Nullify?
Initial connection takes about an hour, and AI prioritization needs two to three weeks tuned to a codebase before it's fully dialed in. Install the Nullify GitHub App and connect the repositories to scan, and detection for secrets, vulnerable code, and container misconfigurations starts on the very next commit. Jira Cloud and Slack integrations can be added afterward for ticket sync and alerting.
