Why Phantom · vs Legacy NMS
Traditional network monitoring watches interfaces and thresholds. That's necessary — and nowhere near enough for BGP paths, multicast trees, MPLS VPNs, or predicting a change. Phantom complements it, then often consolidates it.
| Question | Legacy NMS | Phantom |
|---|---|---|
| Is a port up/down? | ✓ | ✓ |
| Why did the BGP path change? | — | ✓ attributes + history |
| Is my multicast tree intact? | — | ✓ mroute + RPF |
| Are my VPNs still isolated? | — | ✓ VRF route-targets |
| What will this change break? | — | ✓ digital twin + AI |
| What's my attack surface? | — | ✓ attack-path + scan |
