Hetzner DDoS Protection
Pros
- + Free and automatic for every Hetzner customer, with no scrubbing or per-gigabit charges during attacks
- + Nokia Deepfield Defender edge mitigation (since March 2026) filters most attack traffic before it enters the backbone
- + Distinguishes attack types (e.g. UDP flood vs SYN flood) instead of reacting to raw volume alone
- + Filtering stays inside Hetzner's own German/Finnish network, supporting GDPR data-sovereignty requirements
- + Covers all Hetzner products at once: cloud servers, dedicated root servers, web hosting, load balancers
Cons
- - Protects Hetzner infrastructure only; useless for non-Hetzner origins
- - Zero user control: no configurable thresholds, no dashboard, no WAF rules
- - No published mitigation capacity, detection SLA, or uptime credits tied to the service
- - Non-EU locations (Ashburn, Hillsboro, Singapore) not confirmed to run the same mitigation stack
- - Historic community reports of null-routing attacked dedicated servers could not be confirmed against current policy
Cloudflare WAF
Pros
- + WAF engine and managed ruleset included on every plan, including Free
- + Unmetered DDoS absorption at the edge on all tiers
- + Central rules maintenance — no appliances, agents or rule deployments to manage
- + Attack-score and bot-management layers available as needs grow
- + Flat plan pricing; no per-request or per-rule metering
Cons
- - Advanced rate limiting, attack-score rules and full log export are plan-gated
- - Managed rules can block legitimate traffic; tuning requires a logging-first workflow
- - Free plan limits request body inspection to 1 MB
- - Only applies to proxied records — DNS-only traffic is not filtered
- - A compensating control, not a substitute for fixing application vulnerabilities
