DDoS Protection

DDoS protection at the server level , not just the CDN

Cloudflare stops volumetric floods at the edge. ZenoCloud protects your origin — the server behind the CDN that attackers reach the moment your IP leaks. Multi-layer scrubbing with 24/7 human escalation for complex or sustained attacks.

Three layers of DDoS protection

Volumetric attacks, protocol exploits, and application-layer floods require different defenses. ZenoCloud deploys protection at every layer.

Network-layer scrubbing

BGP-level traffic scrubbing upstream of your server filters volumetric Gbps floods — SYN floods, UDP amplification, ICMP floods — before they reach your infrastructure. Works in tandem with Cloudflare for defense-in-depth.

Server-level rate limiting

iptables rate limiting, fail2ban rules, SYN cookie protection, and connection throttling applied directly on your server. Stops protocol-layer attacks (SYN floods, slow-read attacks) that pass the network layer.

Application-layer (L7) WAF

HTTP flood detection, Slowloris mitigation, API rate limiting, and bot fingerprinting. Integrated with Managed WAF — see /security/managed-waf/ for application-layer coverage. L7 attacks are stopped before they exhaust PHP, MySQL, or Node processes.

Real-time traffic monitoring

Continuous traffic pattern analysis with automated anomaly detection. When deviation from baseline exceeds thresholds, automated mitigation triggers and the on-call engineer is notified simultaneously.

Human escalation for complex attacks

Automated rules handle most attacks. Complex, sustained, or adaptive attacks (attackers rotating IPs, changing vectors mid-attack) get human engineer review within 15 minutes. We adjust rules in real time.

Post-attack incident report

After every significant attack: attack vector classification, peak traffic volume, mitigation actions taken, and recommendations for hardening. Useful for DPDP and ISO 27001 incident documentation.

DDoS protection: Cloudflare CDN vs ZenoCloud origin protection

Cloudflare and ZenoCloud are complementary, not competing. Cloudflare protects the edge; ZenoCloud protects the origin server that attackers bypass when your real IP leaks.

FAQ

DDoS protection questions

What types of DDoS attacks do you protect against?
Volumetric attacks (UDP floods, ICMP amplification, DNS amplification at the network layer), protocol attacks (SYN floods, TCP RST floods at the transport layer), and application-layer attacks (HTTP floods, Slowloris, WordPress XML-RPC abuse, API scraping). The combination of network scrubbing + server rate limiting + WAF covers L3 through L7.
Will DDoS protection block my legitimate traffic?
False positives are a real risk with aggressive DDoS rules. Our approach: initial tuning in detection mode (log-only) for 7–14 days to baseline your normal traffic patterns. We whitelist known good IPs, CDN ranges, and your application's expected traffic fingerprint before enforcing. False positives do occur, especially during new attack patterns, but human engineers review within 15 minutes of any enforcement decision.
Do you guarantee my site stays up during an attack?
We do not promise 100% uptime during attacks — anyone who does is overselling. What we do guarantee: automated mitigation fires in under 60 seconds, an engineer is engaged within 15 minutes, and we exhaust all mitigation options before declaring the attack beyond our current capacity. Our 99.99% uptime SLA covers normal operations; major sustained attacks by well-resourced adversaries can exceed any mitigation capacity.
Does DDoS protection work with Cloudflare?
Yes, and we recommend running both. Cloudflare handles edge-layer protection; ZenoCloud protects your origin server. If your real server IP is ever exposed (DNS misconfiguration, API leak, historical DNS records), Cloudflare's protection is bypassed entirely. ZenoCloud's server-level protection is your safety net. We configure both layers to avoid conflicting rate limits.
How do you handle game server DDoS attacks?
UDP-based gaming protocols (common targets for L3/L4 floods) require specific handling — standard TCP rate limiting doesn't apply. If you run game servers, mention it when you contact us. We configure UDP-specific filtering and work with your upstream provider on protocol-level protections.
Is DDoS protection included in any hosting plan?
Basic network-level DDoS protection is included in all ZenoCloud managed hosting plans. The DDoS add-on described here adds application-layer L7 protection, WAF integration, and human escalation with incident reports — the more active managed layer on top of the baseline infrastructure protection.

Cloudflare isn't enough if your server IP is exposed. Add origin-level DDoS protection with human escalation — talk to our security team.
