Neurowall drops attack traffic at the network driver level — before the Linux kernel allocates memory for it. Legitimate traffic continues flowing. Applications stay online.
Even modest attacks can overwhelm under-provisioned infrastructure. Cloud-based mitigation adds latency. Traditional appliances need expensive upgrades.
Attack traffic grows year over year. Infrastructure designed for normal traffic levels may not absorb even moderate attacks.
Scrubbing center redirects add round-trip latency for all traffic — attack or legitimate. On-premise filtering keeps latency low.
Traditional appliances require hardware upgrades to handle higher attack volumes. Software filtering scales with CPU and NIC.
Manual mitigation during an attack costs time. Pre-configured rate limits and blocklists activate automatically.
Because XDP runs at the network driver, dropped packets never allocate kernel memory, never traverse netfilter, and never reach userspace. The per-packet cost of a drop decision is measured in nanoseconds.
During sustained attacks, the system remains responsive for legitimate traffic. CPU usage scales with packet rate — not attack sophistication.
| Mechanism | Description |
|---|---|
| Per-source rate limiting | Token bucket algorithm — limits packets per source IP before they overwhelm services |
| IP blocklists | Block known attack sources via AbuseIPDB, OTX, MISP, and custom threat feeds |
| CIDR-based filtering | Block entire subnets associated with attack infrastructure |
| Protocol filtering | Drop traffic on unused protocols to reduce attack surface |
| Connection tracking | Identify and filter stateless flood traffic |
| DNS sinkhole | Prevent DNS amplification by blocking known reflector domains |
| Allowlist bypass | Trusted sources always pass — protection never blocks legitimate partners |
Keep applications online during attacks. Filter at the edge, not at the application layer where damage is already done.
Attack traffic is absorbed at the gateway. Backend services, databases, and internal infrastructure remain unaffected.
On-premise protection without per-attack cloud scrubbing charges. Predictable cost regardless of attack frequency.
Pre-configured rate limits and blocklists activate the moment attack traffic arrives. No manual intervention required.
Deploy across multiple gateways for defense at every network entry point. Centrally managed from one control plane.
