Why Phantom
Legacy NMS stops at up/down. Cloud observability wants your data. Phantom gives you cloud-grade depth plus AI change intelligence, running entirely on your own infrastructure.
The landscape
| Capability | Legacy NMS | Cloud observability | Phantom |
|---|---|---|---|
| Up/down & SNMP counters | ✓ | ✓ | ✓ |
| BGP / multicast / VRF / MPLS depth | limited | partial | ✓ deep |
| Time-series protocol history | — | ✓ | ✓ |
| Change prediction (digital twin + AI) | — | — | ✓ |
| Failure-impact simulation | — | partial | ✓ |
| Security / attack-path from same data | — | — | ✓ |
| Fully self-hosted / air-gap | ✓ | ✗ cloud | ✓ |
| On-prem AI (no data egress) | — | ✗ | ✓ |
Illustrative comparison of typical category capabilities, not a claim about any specific vendor's roadmap.
Great for up/down. Phantom answers what it can't: why the path changed, what a change will break, is my multicast tree intact, is my OT/IT still isolated. Complement — then consolidate.
Cloud-grade depth without the cloud. Your configs and topology — and the AI that reasons over them — never leave your network. The answer when SaaS is a hard no.
In one line
Cloud observability's depth, on your own infrastructure — plus AI that predicts change instead of just charting the past.
