Depthfirst vs Pi Security (2026)
Both find and fix software vulnerabilities autonomously and depthfirst documents considerably more, 11 of 14 against 7. depthfirst detects, triages and remediates software vulnerabilities, priced by codebase size, developer count and modules.
Pi builds a security brain of your code, cloud and history, then autonomously finds and ships fixes across the software development lifecycle. The historical context Pi builds is the interesting differentiator: a vulnerability that keeps returning is a different problem from one that appeared yesterday, and most tools cannot tell them apart.
Choose Depthfirst if
- Documented coverage is materially broader and it will show across a large codebase.
- Triage is the bottleneck: you already have findings and cannot work through them.
- Pricing scaled to codebase and team size maps to how you would justify this.
Choose Pi Security if
- Recurring vulnerabilities are your pattern, and history is what explains them.
- Cloud context alongside code is required because your risk spans both.
- Shipping fixes across the whole lifecycle, not only flagging them, is the outcome.
