Executive Summary
AI and cloud-native development have accelerated how systems are built and made them harder to secure over time. The traditional build-versus-buy decision for threat modeling now includes a third option: using AI directly. Organizations typically weigh three approaches:
- Build an internal solution
- Buy a purpose-built platform
- Use AI or LLMs directly
The question that mattters: Which approach stays effective as your environment keeps changing?
This paper examines the tradeoffs across all three paths, where each one helps, and where each one runs into practical limits as scale, volatility, and assurance requirements rise.
