| Feature / Outcome | comBOX Virtual Leased Line | Typical SD-WAN |
|---|---|---|
| Link aggregation | ✅ Aggregates bandwidth from all WANs simultaneously | ❌ Uses only one active link per flow (no true bonding) |
| Performance on unstable / wireless links | ✅ Maintains performance through per-packet distribution + FEC | ⚠️ Performance drops / packet loss → QoS issues |
| Latency optimization | ✅ Low-latency routing via private backbone | ⚠️ Public Internet path only |
| Failover | ✅ Seamless, no session drop (VoIP/Apps stay up) | ❌ Session drops when failover occurs |
| Symmetrical speed | ✅ Achievable — uplink bonding | ⚠️ Typically relies on primary wired uplink |
| Data-capped links (LTE/Starlink) | ✅ Selective bonding only for critical apps | ❌ Hard to control consumption |
| SLA | ✅ 99.95% SLA comparable to leased line | ⚠️ Dependent on ISP SLAs |
| Infrastructure needed | Fully managed — partner resells | Usually requires partner-managed SD-WAN controllers |
| Use case focus | Hybrid WAN, rural, maritime, mobility, mission-critical | Enterprise branch offices with stable fiber links |
A multinational organization operating several secure sites across Eastern Europe required an enterprise-grade, carrier-neutral connectivity solution to ensure uninterrupted operations, even in regions with limited infrastructure.
