Nullify is an agentic (AI native) product security and application 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 and last mile communication. Nullify's core capabilities include finding vulnerabilities across code (SAST), dependencies (SCA), secrets, APIs, and containers, including business logic flaws such as cross-tenant abuse, IDOR, authorization bypass, and more. The platform generates exploit hypotheses for these findings 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. Nullify uses cloud context to reduce false positives to near-zero. The triage engine evaluates each finding using runtime reachability, network exposure, and cloud 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 policies, bug bounty reports, pentest reports, and repository metadata. "Campaigns" handle remediation, which bundles validated vulnerabilities, identifies the appropriate developer owner, opens merge-ready pull requests in GitHub, self-heal those PRs based on CI logs, and escalate unresolved issues via messaging tools (Slack, etc) to maintain SLA compliance. Nullify integrates with code, cloud, ticketing, and messaging tools. 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.
