DepthFirst introduces dynamic Threat Model to empower AI security agents
andreamichi · x · 2026-08-14
DepthFirst Labs introduced 'Threat Model,' a living security artifact that captures a repository's architecture, trust boundaries, and attacker-controlled inputs. This feature aims to solve the inefficiency of traditional security tools starting every finding from scratch by providing durable context for vulnerability discovery.
The team described this as a fun human-agent collaboration challenge, allowing users to keep threat models up to date while tuning them as needed. The threat model is now applied across their entire product suite, ranging from Code and Security Reviewers to their Agentic Pentester.
