Key features

  • Works across Microsoft Copilot, Glean, Gemini, and other enterprise AI assistants
  • Audit logs for AI-system data access

  • Governance dashboards for security and compliance teams
  • Virtual databases over existing infrastructure with no data movement
  • Built-in anonymisation at the access layer
  • Security and governance controls applied per query
  • AI analysis on live data rather than a duplicated copy
Pros
  • Addresses a specific, underserved risk, LLM oversharing, rather than general AI security
  • Award recognition from both RSA and Black Hat in 2024 signals credibility in the security community
  • Works across multiple enterprise AI assistants rather than locking into one vendor
  • Avoids the extra copy that creates new security and cost exposure
  • Governance sits at the access layer rather than being bolted on
Cons
  • Enterprise-only pricing (reportedly around $50,000/year) puts it out of reach for smaller organizations
  • Founded in 2023, so long-term efficacy data is still limited
  • Effectiveness depends on how well existing data-classification policies are set up beforehand
  • Aimed at established data estates, not small or greenfield setups
  • Virtualisation adds a layer to debug when queries behave oddly
