| Fact | PromptGuard | ZeroTrusted AI Firewall |
|---|---|---|
| Deployment | The product offers managed cloud, hybrid self-hosting, and air-gapped deployment; air-gapped licences validate offline with a signed key. | The listed modes are inline proxy for production-path enforcement, out-of-band traffic mirroring for detection and policy tuning, and browser or edge enforcement when combined with Shadow AI Protection. |
| Latency | Deterministic fast-path checks are advertised as taking under 10 milliseconds, while escalated checks are network-bound. | The maker says inline deployment adds under a millisecond to most inference paths and out-of-band monitoring has zero production-path latency impact. |
