Best for
  • GRC and third-party risk teams
  • Security teams tracking vendor AI features
  • Procurement processes involving AI tools
  • Enterprises deploying LLM copilots and agents
  • Security and AppSec teams needing AI visibility
  • Regulated organizations governing employee AI use
Pros
  • Focuses on an under-served problem (third-party AI risk)
  • Founders and team have real AI security-research credibility
  • Publishes notable vulnerability research
  • Complements GRC and vendor-risk processes
  • Lightweight, intelligence-oriented approach
  • Purpose-built for generative-AI and agent risks rather than retrofitted
  • Covers the full lifecycle: discover, assess, test, enforce
  • Shadow-AI discovery surfaces usage security teams often miss
  • Low-latency guardrails designed to sit in the request path
  • Flexible deployment via gateway, API, or SDK
Cons
  • Very early-stage with minimal disclosed funding (~$3M)
  • Narrow scope compared with full AI-security platforms
  • No public pricing or free tier
  • Small team and limited track record
  • Not a runtime protection or guardrail product
  • No public pricing; everything is sales-gated
  • No free plan or self-serve trial
  • Enterprise focus makes it a poor fit for small teams
  • Fast-moving, crowded market makes durability hard to judge
  • Effectiveness depends heavily on correct deployment and tuning
