Where do they differ?
- On-device control: Bloom partly describes it; Koi describes it.
- Names the coding agents it covers: Bloom is not in our sources; Koi matches.
- Rolls out through EDR or device management you run: Bloom is not in our sources; Koi partly matches.
- Can block an agent, tool or action: Bloom partly matches; Koi matches.
- Also covers SaaS, cloud or homegrown AI: Bloom is not in our sources; Koi partly matches.
Choose Bloom if
- Your first worry is unvetted extensions and packages arriving on developer machines
- You want an inventory of everything on the endpoint before you write AI-specific rules
Choose Koi if
- You already run Palo Alto Networks Cortex XDR
- You want to find and remove risky extensions and packages across the fleet
Which limits should you check?
Bloom
- Deployment method and pricing are not published.
- Decisions on individual tool calls and an activity record are not described on the pages we read.
- Limited company information on its own pages: they do not name investors; funding is known from press coverage (Ctech, 30 July 2026).
Koi
- Agent-based: it adds an agent unless you run it as a Cortex XDR module.
- Warn or ask actions and a record that separates a person from an agent are not described on the pages we read, and no pricing is published.
