Where Legion Security is ahead
- Published evidence, 5 against 4. Five figures, all grade C, but two carry named customer sources (WELL Health, The University of Tulsa).
- Integration transparency, 4 against 3. Claims to work 'with or without APIs' through the browser; no connector catalog or count.
Where Mate Security is ahead
- Use-case breadth, 9 against 7. Four of the seven use cases have a product or feature page; insider risk, exposure and security engineering are one-line tiles.
- Context grounding, 9 against 8. The Security Context Graph stores memories with source, confidence and freshness, and Mate says it learns from tickets and documents in hours.
- Pricing transparency, 4 against 2. No pricing page; one AWS Marketplace line of 150,000 USD for 12 months with no defined usage unit.
- Momentum and recognition, 9 against 6. Seed in 2025-11, Series A on 2026-07-28, Gamebooks on 2026-08-26 and a Gartner emerging-vendor logo in 2026-07.
Verdict by situation
- Lean SOC: For a lean SOC, Mate Security leads 6.35 to 5.70, mostly on pricing transparency (4 against 2); Legion Security only makes sense if that criterion matters little to you.

- Microsoft estate: For a Microsoft-centred estate, Mate Security leads 6.20 to 5.65, mostly on use-case breadth (9 against 7); Legion Security only makes sense if that criterion matters little to you.
- Regulated and audited: For a regulated or audited organisation, Mate Security leads 6.15 to 5.90, mostly on published evidence (4 against 5); Legion Security only makes sense if that criterion matters little to you.
- MSSP: For an MSSP, Mate Security leads 6.35 to 5.80, mostly on use-case breadth (9 against 7); Legion Security only makes sense if that criterion matters little to you.
