VPN Hosting with DDoS Protection — Always-On Defense

VPN servers are uniquely vulnerable to DDoS attacks for several reasons. Their IP addresses are necessarily exposed to every connected client, making them easy to target. VPN protocols like WireGuard and OpenVPN use well-known UDP ports that attackers can flood with minimal effort. And because VPN users depend on continuous connectivity, even brief disruptions cause immediate, noticeable impact.

For personal VPN users, a DDoS attack means losing your privacy protection at a potentially critical moment. For VPN providers, downtime directly impacts revenue, reputation, and customer trust. In both cases, the cost of not having DDoS protection far exceeds the cost of implementing it. A VPN that goes offline when attacked is a VPN that cannot be relied upon.

Adversaries who target VPN servers range from opportunistic script kiddies to sophisticated state-level actors. Journalists using VPN servers in restrictive countries may face government-directed attacks designed to force them onto monitored networks. VPN providers may face attacks from competitors or extortionists. Whatever the threat, DDoS protection ensures your VPN remains your shield.

AnubizHost's DDoS protection operates at the network edge, filtering malicious traffic before it reaches your VPN server. Our mitigation infrastructure can absorb volumetric attacks exceeding multiple terabits per second, handling even the largest attacks without impacting your server's performance or availability. Legitimate VPN traffic passes through unaffected while attack traffic is scrubbed and dropped.

Our protection is always on — there is no manual activation required and no delay while attack detection kicks in. We analyze traffic patterns continuously and begin mitigation within seconds of detecting anomalous traffic. This near-instant response ensures that your VPN users experience minimal disruption even during the initial moments of an attack.

We protect against all common DDoS attack vectors including UDP floods, SYN floods, DNS amplification, NTP amplification, and application-layer attacks. Our filters are specifically tuned for VPN protocols, allowing legitimate WireGuard and OpenVPN traffic through while blocking attack traffic that mimics VPN handshakes or exploits protocol-specific vulnerabilities.

Generic DDoS protection can interfere with VPN connectivity by incorrectly classifying legitimate VPN traffic as malicious. AnubizHost's protection is specifically designed for VPN workloads, with protocol-aware filtering that understands WireGuard handshakes, OpenVPN control channels, and IKEv2 exchanges. This deep protocol understanding ensures that mitigation never disrupts your VPN users' connections.

Our VPN-specific protection also includes rate limiting per source IP, preventing any single source from overwhelming your VPN server's handshake capacity. This is particularly important for WireGuard, which performs a CPU-intensive Noise protocol handshake for each new connection. By rate limiting handshake attempts, we prevent handshake flood attacks that could consume your server's processing resources.

For VPN providers who assign their customers dedicated ports, we offer per-port DDoS protection that isolates attack mitigation to the affected port without impacting other customers on the same server. This granular approach means a DDoS attack targeting one user does not affect service quality for your other customers.

DDoS protection is included at no additional cost on every AnubizHost VPN hosting plan. Whether you choose a budget VPS or a high-performance dedicated server, your VPN server benefits from the same enterprise-grade DDoS mitigation. We believe that DDoS protection is a baseline requirement for VPN hosting, not a premium add-on.

Our standard DDoS protection handles volumetric attacks up to several terabits per second and application-layer attacks up to millions of packets per second. For VPN providers and organizations that face particularly aggressive threat actors, we offer enhanced protection tiers with additional mitigation capacity, dedicated scrubbing resources, and custom filtering rules.

All DDoS-protected VPN hosting plans include real-time attack dashboards where you can monitor attack traffic, mitigation actions, and clean traffic statistics. Our support team is available around the clock to assist with any DDoS-related issues and can implement custom mitigation rules if you face novel attack patterns. Keep your VPN online against any threat with AnubizHost DDoS-protected hosting.
