Nullify is a product security company that packages security expertise into a fleet of autonomous AI agents. Many fast-growing software companies lack the headcount to staff a full application security team, yet they face the same threats as large enterprises: vulnerable code, risky dependencies, and accidentally committed secrets. Nullify addresses this by deploying what it calls an 'autonomous AI workforce' that continuously scans code, surfaces and prioritizes genuine vulnerabilities, and helps remediate them inside the developer's normal workflow.
The platform spans the core pillars of application security. It performs static analysis of source code to find vulnerabilities, scans dependencies for known issues, and detects secrets such as leaked API keys before they cause harm. Crucially, Nullify focuses on cutting through noise — triaging findings so engineers see the issues that actually matter rather than an overwhelming wall of alerts — and assisting with fixes so remediation is fast and low-friction.
Because it operates as a code-scanning bot embedded in developer workflows, Nullify fits the way engineering teams already work, surfacing findings and fixes in the tools and pipelines they use. This developer-first, automation-heavy approach lets smaller teams achieve a security posture closer to that of organizations with dedicated AppSec staff.
Founded in 2022, Nullify targets midsized enterprises and high-growth SaaS companies that need scalable security without scaling a security team. The company has raised approximately $16.9M to date, including a $12.5M round to accelerate deployment of its AI security agents across more customers. As AI accelerates code production, Nullify positions autonomous security agents as a necessary counterpart that keeps pace with the volume of code being shipped.
