Depthfirst

What it does

depthfirst is a security platform that applies autonomous AI agents to source code, dependencies, coding-agent output, and running applications. It produces findings, exploitability results, and merge-ready pull requests with proposed fixes. Its components include a Code Scanner, Dependency Firewall, Security Reviewer, and Agentic Pentester, plus detection of secrets across codebases, CI/CD pipelines, and runtime environments.

The Security Reviewer checks human- and AI-written changes before merge, and the Agentic Pentester tests a running application to confirm which findings are actually exploitable and replays the attack after each fix merges. A Supply Chain component traces dependencies to the code that calls them. The company also publishes dfbench, its own benchmark of detection, validation, and differential-analysis results across models; these figures are vendor-reported.

It suits security and product-security teams at software companies that ship code frequently, including teams using AI coding agents, and want validated, fixable findings rather than long scanner reports. Access starts with a demo request, and existing users sign in at app.depthfirst.com. Pricing and deployment options are not published, so confirm cost and setup details with the vendor.

What it can do

• Scans code for business-logic and data-flow vulnerabilities (Code Scanner)
• Blocks malicious packages before they enter the environment (Dependency Firewall)
• Reviews human and AI-generated code changes before merge (Security Reviewer)
• Validates exploitability by testing running applications (Agentic Pentester)
• Traces dependency risk to reachable code paths (Supply Chain)
• Detects and validates secrets across codebases, CI/CD, and runtime

Before you choose

• No public pricing was found; cost must be confirmed directly with the vendor.
• Benchmark results are vendor-published and model-specific; validate against your own codebase.
• Agentic Pentesting targets running applications, so access to a test or staging environment may be needed.
