The honest brief
Lasso Security
Covers the full GenAI security lifecycle — shadow-AI discovery to runtime guardrails — as one product, not bolt-ons.
- Shadow-AI discovery for third-party use
- Runtime guardrails + red-teaming
- Gateway, API, or SDK deploy
- Cloud and on-prem coverage
- Paid, enterprise-oriented
- No transparent public pricing
- Heavier setup than a guard library
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
