How do CrowdStrike Falcon Guardian and Bloom Security compare on each criterion?
| Criterion | Weight | CrowdStrike Falcon Guardian | Bloom Security | Edge |
|---|---|---|---|---|
| Visibility | 22% | 8 | 9 | Bloom Security |
Why these scoresCrowdStrike Falcon Guardian: Discovers shadow AI agents, including token consumption, on supported Windows, macOS and Linux endpoints, and ties prompts, skill use, tool calls and MCP servers to what runs next. Bloom Security: Discovers software, extensions, AI tools and everything running on the endpoint, with who built it and what it can access. | ||||
| Tool-call control | 20% | 8 | 6 | CrowdStrike Falcon Guardian |
Why these scoresCrowdStrike Falcon Guardian: Connects to Claude Code's hook events to check and block prompts and tool activity as they happen, and returns allow or block before a Copilot Studio agent runs a tool. Bloom Security: Defines what AI agents can access, execute and transmit and scales back overpermissioned MCP servers; runtime tool-call decisions not detailed. | ||||
| Policy | 15% | 6 | 7 | Bloom Security |
Why these scoresCrowdStrike Falcon Guardian: Sets which supported AI agent types may run on managed endpoints, with policy assigned through Falcon host groups; ask, warn or simulate actions are not described on the pages we read. Bloom Security: Blocks malicious or policy-violating packages and skills across npm, Chrome Web Store and Open VSX. | ||||
| Identity and audit | 12% | 8 | 4 | CrowdStrike Falcon Guardian |
Why these scoresCrowdStrike Falcon Guardian: Ties Claude Code events to a specific session and user in Falcon Next-Gen SIEM, and links prompts and tool calls to identity and downstream execution for supported agents. Bloom Security: Not described on the pages we reviewed. | ||||
| Footprint | 13% | 7 | 4 | CrowdStrike Falcon Guardian |
Why these scoresCrowdStrike Falcon Guardian: Delivered through the Falcon sensor; Claude Code coverage is a settings-file entry with no extra agent to install. A third-party report (SACR) adds browser extensions, gateway integrations, an SDK and an MCP proxy, and says prompt-layer telemetry needs network connectivity. Bloom Security: Deployment method not published. | ||||
| Breadth | 8% | 9 | 5 | CrowdStrike Falcon Guardian |
Why these scoresCrowdStrike Falcon Guardian: Covers AI agents from endpoint to cloud and SaaS, including Copilot Studio agents, with Falcon Adversary OverWatch threat hunting extended to AI agents; the AI gateway is listed as coming soon. Bloom Security: Endpoint focused, including non-AI software. | ||||
| Maturity | 10% | 8 | 4 | CrowdStrike Falcon Guardian |
Why these scoresCrowdStrike Falcon Guardian: Part of the CrowdStrike Falcon platform, with a documentation site and earlier releases as Falcon AIDR; Falcon Guardian pricing is not on CrowdStrike's pricing page, and the 99% efficacy and 100 ms figures come from CrowdStrike's internal benchmark testing. Bloom Security: Limited public company information; SOC 2 listed; investors and pricing not published. | ||||
| Total | 100% | 7.7 | 6.0 | CrowdStrike Falcon Guardian |
