The Null-Route Problem: When an attacker sends a 50 Gbps flood to a traditional Indian host, the NOC null-routes (blackholes) the target IP. The host saves bandwidth, but your business goes completely dark.
1. Multi-Stage Inline Filtering Architecture
HostCraft utilizes carrier-grade Corero SmartWall scrubbing appliances positioned inline directly behind our Juniper MX edge routers in Delhi and Mumbai. Every packet passing into our autonomous system (ASN) is inspected in sub-millisecond hardware:
- Stage 1 (Volumetric L3/L4 Dropping): Dropping invalid TCP flags (XMAS, NULL scans), oversized ICMP fragments, and known amplification source ports (NTP 123, SNMP 161, CLDAP 389) at wire speed.
- Stage 2 (Stateful Challenge-Response): Issuing hardware SYN cookies to validate real TCP clients before opening connections to customer virtual machines.
- Stage 3 (Layer-7 Game & HTTP Heuristics): Protocol signature validation for Minecraft, FiveM, Rust, and HTTPS queries, dropping spoofed payloads without adding artificial ping latency.
2. Zero Packet Routing Latency
Because scrubbing is handled domestically at edge exchanges (DE-CIX Mumbai and NIXI Delhi), clean customer traffic is never rerouted to European or North American scrubbing centers, preserving strict sub-15ms Indian ping times.
