depthfirst Reviews & Product Details

depthfirst is an AI-native security platform offering continuous cyber defense. It reasons through code, infrastructure, and business logic to understand how systems work and build a threat model. That context helps depthfirst find and verify vulnerabilities, prioritize what is exploitable, block malicious dependencies, and help teams remediate security issues. The platform covers three broad areas: Code Security reviews repositories and pull requests for vulnerabilities, secrets, insecure dependencies, and business-logic flaws. It connects findings to application context so security and engineering teams can focus on the issues that matter and fix them in the code. Agentic Pentesting uses autonomous agents to attack running applications like a team of elite security researchers. It supports black-, gray-, and white-box testing for new vulnerability discovery, but can also confirm whether code scan findings are exploitable and replay attacks to verify that fixes work. Dependency Firewall blocks malicious packages before installation to prevent supply chain attacks. It applies a shared security policy at the artifact-repository layer and on managed devices, protecting both people and AI agents. depthfirst routes each task to the best-suited AI model to optimize performance and cost. It also includes dfs-large1, depthfirst’s own frontier cybersecurity model, which performs comparably to frontier general-purpose models on vulnerability detection tasks at a fraction of the cost. depthfirst works with enterprises such as ServiceNow, government agencies, and innovative AI and fintech companies including Lovable, Supabase, Ripple, Listen Labs, fal, and MoonPay.
