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 entire vulnerability lifecycle: continuous detection of secrets, vulnerable code, infrastructure-as-code flaws, container misconfigurations, and dependency vulnerabilities; autonomous triage and prioritization using threat intelligence specific to your tech stack; and automated remediation with production-ready patch generation. The core technology combines AI-driven code analysis with real cloud reachability assessment. Unlike traditional SAST (static application security testing) tools that flag every potential issue, Nullify determines whether a vulnerability is actually exploitable based on permission boundaries, runtime exposure, and organizational context. This intelligent filtering dramatically reduces false positives: the platform achieves a 90% merge-ready rate on auto-generated vulnerability fixes. Nullify integrates seamlessly into developer workflows as a GitHub App, automatically scanning every commit and pull request. Results integrate with Jira Cloud for two-way ticket synchronization and Slack for alerting. The platform uses generative AI to match your codebase patterns, error handling conventions, and coding style when generating patches, increasing patch adoption and reducing developer friction. Backed by $17.8M in funding from SYN Ventures, Two Sigma Ventures, and Black Nova Venture Partners, Nullify has already saved customers 48,000+ hours of manual security work and automatically resolved over 450 vulnerabilities. The platform is purpose-built for small-to-mid-sized security teams and development organizations that lack dedicated AppSec engineers. Pricing is straightforward with the Pro tier at $800/year and Enterprise plans for larger organizations needing API access, single sign-on, and custom integrations. The Pro tier supports unlimited repositories, users, and detections.

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 finds business logic flaws, injection vulnerabilities, authorization bypasses, and container misconfigurations while filtering false positives using cloud reachability and permission analysis.
  • Secrets Detection & Validation: Automatically detects hardcoded credentials, API keys, and sensitive data in repositories, then validates whether secrets are live and exploitable by testing actual access.
  • Automated Remediation: Generates production-ready pull requests with fixes matching your codebase patterns, error handling, and coding style, achieving 90% developer merge rate without manual tweaking.
  • Threat Intelligence Integration: Tracks actively exploited CVEs and zero-day vulnerabilities affecting your specific dependencies, prioritizing fixes by real-world exploitation likelihood and business impact.
  • GitHub App Integration: Native GitHub App scans every commit and pull request automatically. Works seamlessly in developer workflows with Jira Cloud two-way sync and Slack alerting.
  • AI-Powered Triage: Autonomous AI agents investigate vulnerabilities continuously, analyze impact from your organizational context, and route one-click fixes directly to developers without manual review.

Pros

  • AI triage eliminates 90% of false positives: autonomous agents analyze cloud reachability and permission boundaries to surface only exploitable vulnerabilities, dramatically reducing developer alert fatigue compared to traditional SAST tools flagging thousands of issues.
  • Production-ready patches match your codebase style: AI-generated fixes adapt to your error handling, logging frameworks, and coding conventions, resulting in 90% merge-ready rate without developer rework.
  • Saves 48,000+ developer hours: customers report typical time savings of 20+ hours per developer per year via automated detection and remediation, equivalent to hiring additional security engineers without salary overhead.

Cons

  • No free tier and minimum $800/year entry point excludes solo developers and small teams with minimal security budgets; free tier would accelerate adoption.
  • Learning curve for optimal AI tuning: getting prioritization calibrated to your specific environment requires 2-3 weeks of configuration, with initial setup taking approximately 1 hour.
  • Limited integration ecosystem: strong GitHub/Jira/Slack support but missing integrations for Azure DevOps, GitLab, Linear, and other developer tools, limiting use at enterprises with diverse toolchains.

Frequently Asked Questions

What is Nullify and what does it do?

Nullify is an AI-powered autonomous security platform that automates application security (AppSec) from end-to-end. It continuously scans code repositories for vulnerabilities, secrets, misconfigurations, and dependency issues; uses AI to intelligently triage and prioritize findings by real exploitability; and generates production-ready patches that developers can merge without manual rework. Founded in 2022, Nullify has saved customers 48,000+ hours of manual security work.

How much does Nullify cost?

Nullify's Pro tier costs $800 per year (approximately $67/month) and includes unlimited repositories, users, and detections. There is no free tier. Enterprise plans are available with custom pricing for organizations needing API access, single sign-on, advanced integrations, and dedicated support. Annual commitment is required for all tiers.

What are the main features of Nullify?

Key features include: (1) Intelligent vulnerability detection using cloud reachability analysis to filter false positives, (2) Automated secrets detection with validation of whether credentials are actually live and exploitable, (3) AI-generated patches matching your codebase style and conventions, (4) Real-time threat intelligence tracking actively exploited CVEs in your dependencies, and (5) GitHub App integration with Jira Cloud and Slack for workflow automation.

Is Nullify free to use?

No, Nullify does not offer a free tier. The Pro tier starts at $800/year with unlimited repositories and users. This is a paid service designed for small-to-mid-sized security teams and development organizations that need to automate security but cannot afford traditional SAST tools or dedicated security engineers.

What are the best alternatives to Nullify?

Main alternatives include Checkmarx One (comprehensive SAST with higher cost), CrowdStrike Falcon (broader cloud security), GitLab Ultimate (built-in AppSec), GitHub Advanced Security (GitHub-native), and Snyk (developer-focused dependency scanning). Choose Checkmarx for enterprise breadth. Choose GitLab for integrated DevOps. Choose Snyk if you need dependency-first focus. Nullify excels at false positive reduction and merge-ready patch generation for SMBs.

Who is Nullify best for?

Nullify is ideal for small security teams (1-3 engineers) at SMBs and mid-market companies needing to scale AppSec without hiring additional staff. It suits DevSecOps teams implementing shift-left security in CI/CD pipelines and engineering leaders automating vulnerability management across 50+ repositories. It is less suitable for solo developers, enterprises with mature AppSec programs, or organizations using non-GitHub version control systems.

How does Nullify integrate with my development workflow?

Nullify integrates as a GitHub App that automatically scans every commit and pull request in your repositories. Vulnerability findings sync with Jira Cloud for two-way ticket management, and alerts post to Slack for team notification. The platform supports GitHub and Bitbucket Cloud. Enterprise tier offers REST API access for custom integrations with other security tools and ticketing systems.
