DepthFirst

DepthFirst is an AI-native security platform company that detects complex software vulnerabilities by treating code, business logic, and infrastructure as a unified system. The company positions its approach as an alternative to traditional static analysis and scanning tools, which it argues miss complex flaws and generate excessive false positives. Its stated scope ranges from enterprise systems to critical infrastructure, and it describes its work as protecting software used by billions of people.

The company's flagship product, the DepthFirst AI-Native Security Platform, reports 8x more true-positive vulnerability detection and an 85% reduction in false positives, alongside a 90% improvement on the CyberGym benchmark. Rather than stopping at detection, it delivers ready-to-merge fixes directly into developers' existing workflows - framing security as an accelerant to development rather than a bottleneck to it. DepthFirst also refers to a General Security Intelligence platform, described as the first of its kind.

Technical work spans application security, vulnerability detection, code and business logic analysis, infrastructure security, automated code remediation, and AI/ML threat defence. The company's mission is framed around countering AI-powered threats with AI-native tooling, with a stated aim of protecting against breaches, financial theft and infrastructure attacks. Details on funding, team size and geographic presence are not disclosed.
