Frequently Asked Questions
How much scrubbing capacity do I need for DDoS protection?
▼
Your scrubbing capacity should exceed your peak legitimate traffic by at least 10x to handle volumetric attacks without degradation. Most small-to-medium businesses need 1-5 Tbps of capacity. Enterprises handling high-traffic applications should look for providers offering 10+ Tbps. Always verify that the provider's capacity is available across their entire network, not just at select locations.
What's the difference between L3/L4 and L7 DDoS protection?
▼
L3/L4 protection defends against network and transport layer attacks like UDP floods and SYN floods that target bandwidth and connection tables. L7 protection stops application-layer attacks that mimic legitimate HTTP/HTTPS requests to exhaust server resources. You need both. Network-layer attacks are larger in volume, but application-layer attacks are harder to detect and can take down sites even when bandwidth is available.
How fast should DDoS mitigation activate?
▼
Best-in-class AI DDoS protection detects attacks within 1-3 seconds and starts mitigation immediately. Anything slower than 10 seconds leaves your infrastructure vulnerable to damage during the critical initial attack phase. Always-on protection with continuous traffic analysis eliminates detection lag entirely, making it the preferred approach for mission-critical applications.
What does always-on DDoS protection mean?
▼
Always-on protection routes all your traffic through the provider's scrubbing network 24/7, analyzing every request in real-time even when you're not under attack. This contrasts with on-demand protection, which only kicks in after an attack is detected, introducing critical delay. If your business can't afford any downtime, always-on protection is your best bet. Just know it'll cost more than on-demand alternatives.
How much does enterprise AI DDoS protection cost?
▼
Enterprise AI DDoS protection typically runs $500-$5,000+ per month, depending on your traffic volume, scrubbing capacity, and SLA requirements. Always-on protection with L3-L7 coverage and integrated WAF costs more than basic on-demand network-layer filtering. Most providers structure their pricing in tiers based on bandwidth commitments and attack mitigation guarantees, so you'll need to request custom quotes for accurate pricing.
How do I get started with AI DDoS protection?
▼
Start by measuring your baseline traffic patterns and peak bandwidth requirements, then choose a provider with at least 10x that capacity. Most providers offer BGP-based integration (you announce your IP ranges to their network) or DNS-based setup (you change nameservers to route traffic through their proxy). Implementation typically takes 1-3 days with provider support, and you should run parallel testing before cutting over production traffic completely.
What is AI DDoS protection and why does it matter?
▼
AI DDoS protection uses machine learning algorithms to detect and stop distributed denial-of-service attacks by analyzing traffic patterns in real-time. Unlike signature-based systems that only catch known threats, AI models spot anomalous behavior and zero-day attack vectors automatically.
This matters because modern DDoS attacks evolve rapidly and combine multiple attack types. Only AI-powered systems can adapt fast enough to stop them before they cause downtime.
Conclusion
Choosing the right AI DDoS protection provider comes down to three critical factors: scrubbing capacity that exceeds your peak traffic by at least 10x, detection speed measured in seconds (not minutes), and complete L3-L7 coverage with always-on monitoring. Don't settle for on-demand mitigation that activates only after an attack begins. Modern threats require continuous analysis and instant response. Verify that your provider offers BGP anycast routing, maintains a 100% uptime SLA, and includes incident response support as standard.
Gcore delivers the most complete AI DDoS protection package for businesses that can't afford downtime.
