Open-source, enterprise-grade threat modeling.
The Tooling Gap
Teams today often face a difficult trade-off:
Manual & Ad-hoc
Using whiteboards or simple diagramming tools that don't scale or integrate with code.
Closed & Expensive
Using powerful commercial platforms that are locked behind high licensing fees.
Precogly fills the gap
We provide an open foundation that supports enterprise scale without sacrificing accessibility or developer freedom.
