- Covers injection, jailbreaks, PII, data loss
- Model-agnostic API in front of any LLM
- Behavioral detection risks false positives
- Core product is closed source
- Enterprise pricing quoted by sales
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
