Why Phantom · vs Cloud Observability
SaaS observability platforms are powerful — but they require your network data to leave your environment, which is a non-starter for regulated and critical-infrastructure networks. Phantom keeps it all in-house.
| Dimension | Cloud observability | Phantom |
|---|---|---|
| Protocol-level depth | ✓ | ✓ |
| Where your data lives | their cloud | your infrastructure |
| Air-gap / offline deployment | ✗ | ✓ |
| AI that never sees your data | ✗ | ✓ on-prem LLM |
| Change prediction (digital twin) | partial | ✓ |
| Cost model | per-GB egress / ingest | predictable license |

Cloud observability's depth, on your own infrastructure — plus AI that predicts change instead of just charting the past.
