Cons	Early-stage company and nascent product category Value is tied to which AI assistants you deploy No public pricing or free tier Cloud-only; no self-hosted option advertised Overlaps with native controls in some Microsoft tooling	Enterprise-only, custom pricing with no free tier Requires a sales process to evaluate Independence carries potential acquisition risk Aimed at mature AI/security teams, not individuals Deployment complexity for full coverage
