Precogly

The open-source alternative to commercial threat modeling platforms

Open-source threat modeling tools lack enterprise features. Commercial tools come with heavy price tags and vendor lock-in. Precogly bridges this gap and democratizes threat modeling for every organization in the world.

Key Features

  • Import and export TM-BOM style JSON files — improves interoperability with other threat modeling platforms
  • Collaborative workspaces — team collaboration for threat modeling programs
  • Advanced DFD editor — nested components, trust zones with trust boundaries, and more
  • Community library packs — links to MITRE ATT&CK, CAPEC, LINDDUN, STRIDE, and other taxonomies for high-quality threat models

Who is Precogly for?

  • Security architects looking to scale threat modeling across their organizations
  • Security engineers who need a well-architected foundation for AI-powered threat modeling assistants
  • Threat modeling consultants and trainers looking for a platform that supports reference images, team collaboration, and structured programs
  • Compliance professionals looking to link threat modeling with standards like ASVS or regulations like CRA and DORA

How is Precogly different?

  • Compliance-aware — built-in traceability to DORA, CRA, ASVS, NIST CSF, SOC 2, and more
  • Structured library packs — curated packs with components, threats, countermeasures, and taxonomy links
  • AI-agent ready architecture — a clean REST API with full OpenAPI docs
  • Pack ecosystem — community and official packs for AWS, Azure, GCP, banking, and compliance frameworks
