Nullify is an AI-driven product security automation platform designed to replicate the reasoning and actions of human security engineers. The platform targets software development teams and security organizations, with a focus on automating the full vulnerability lifecycle — from discovery through remediation. Nullify's core capabilities include finding vulnerabilities across code, dependencies, secrets, APIs, and containers, including business logic flaws such as cross-tenant abuse and authorization bypass. The platform generates exploit hypotheses by reasoning through code logic, access control structures, and cloud identity configurations, then validates them through real attack simulation. Only confirmed, impact-verified findings are escalated, each accompanied by a full proof-of-exploit report detailing the attack path, inputs used, and code location. The triage engine evaluates each finding using runtime reachability, network exposure, and AWS cloud context, then assesses business impact using organizational risk data stored in "Vault" — a long-term memory system that ingests unstructured security knowledge such as vulnerability management framework (VMF) policies, bug bounty reports, cloud architecture, and repository metadata. Remediation is handled through "Campaigns," which bundle validated vulnerabilities, identify the appropriate developer owner, open merge-ready pull requests in GitHub, refine fixes based on CI logs, and escalate unresolved issues via Slack to maintain SLA compliance. Nullify integrates with tools including GitHub, GitLab, Jira, Slack, AWS, Bitbucket, Linear, and Datadog. Pricing is usage-based, aimed at small to growing security teams. The platform positions itself as a replacement for multiple point security tools and the manual labor required to operate them.
