The honest brief

Prompt Security

Covers both employee GenAI use (shadow-AI visibility) and homegrown LLM apps in one runtime layer — now backed by SentinelOne.

  • Real-time data-leak prevention
  • Blocks prompt-injection attacks
  • Browser-extension and API coverage
  • Part of SentinelOne Singularity platform
  • Enterprise, paid-only pricing
  • Roadmap tied to SentinelOne integration
  • Heavier than a single-purpose API guard

Protect AI

Secures the whole ML supply chain from model selection to runtime, and stewards the OSS ModelScan tool the field relies on.

  • Covers full AI/ML lifecycle
  • Model scanning for serialization attacks
  • Adds AI red teaming and posture management
  • Now part of Palo Alto Prisma AIRS
  • Enterprise, paid-only
  • Roadmap folding into Prisma AIRS
  • Broad scope, longer to deploy
