Pick CAIRIS if…
CAIRIS suits teams developing systems that need security, usability, and requirements modeling together. Its API and deployment options also fit users integrating design work into a toolchain or self-hosted environment.

ThreatOpus is aimed at security teams, security champions, and platform engineers who need governed threat models and clear merge decisions. Its outputs support security work but are not a substitute for professional assessment or formal risk acceptance.
