CORE CAPABILITIES

One visit, full acceleration & protection

Acceleration, defense, security and certificates — set up at once. You just point your domain over.

Global acceleration & cache

Edge caching serves nearby; static hits served instantly, dynamic smartly fetched — faster TTFB, lighter origin.

High-defense DDoS

Datacenter-grade scrubbing against SYN/UDP/reflection floods. High-defense IP takes the hit, business stays online.

Smart CC defense

Identifies abnormal requests by real client IP and auto-bans attackers — real users unaffected, never a blunt block.

Web Application Firewall

Built-in WAF blocks XSS, SQL injection, path traversal and malicious crawlers, protecting your origin app layer.

Automatic HTTPS

Free certificates auto-issued and renewed, dual-CA redundancy, full-site HTTPS & HTTP/2 with zero ops.

Origin hiding

Only high-defense nodes are exposed; origin IP stays hidden, firewall allows back-to-origin only. No way around it.

SCENARIOS

Protection tailored to your business

Whether you face traffic spikes or sustained attacks, there's a fit.

E-commerce / Marketing

Stable acceleration under flash-sale spikes, blocks malicious CC — protect conversions and reputation.

Gaming / High-adversity

Against sustained DDoS and precise CC: Tbps scrubbing + real-IP detection — holds up, stays smooth.

Enterprise / Gov sites

Compliant, stable, full HTTPS; WAF blocks web attacks — keep your brand front door always online.

API / App backends

Accelerate APIs and mobile backends and block scraping & credential-stuffing; origin open to nodes only.

HOW IT WORKS

Attacks stop at the edge, clean traffic reaches origin

All requests are scrubbed and cached at high-defense nodes first; malicious traffic is blocked, origin only sees clean requests.

FAQ

Frequently asked questions

Do I need to change my website code?
No. Just switch your domain's DNS to CDN Doctor and keep your origin as-is — not a single line of business code changes.
Will it wrongly block my real users?
No. We identify attacks by real client IP and only ban abnormal sources; real users are unaffected — never a blunt block.
Is HTTPS supported? Do I buy a certificate?
Supported and free. Certificates are auto-issued and renewed for your domain (dual-CA), no purchase or manual upkeep.
Will my origin IP be exposed?
No. Only high-defense nodes are exposed; keep your origin firewall open to back-to-origin IPs only, so attackers can't bypass nodes.
What if I'm hit by a large DDoS?
Traffic is scrubbed at datacenter level before reaching origin; under huge attacks we switch high-defense lines to keep you online, with 24/7 standby.
How fast can I go live?
Usually within 5 minutes: register → add domain → update DNS, and certificates, acceleration & protection apply automatically.
