FAQ

Quick answers

01How is anti-DDoS CDN different from normal CDN?

It adds enterprise security—DDoS scrubbing, WAF, bot controls—on top of acceleration so you do not bolt on extra appliances.

02Will protection slow my site?

No. Edge caching and routing reduce latency; mitigation happens at the edge with minimal impact on legitimate users.

03How large an attack can you mitigate?

The platform scales to T-class scrubbing; exact ceilings depend on the plan—enterprise tiers can be customized.

04How fast can I onboard?

Add domains and origins in the console, then update DNS/CNAME—support can assist end-to-end.

05HTTPS and custom certificates?

Full-site HTTPS with TLS 1.3, managed or custom certificates, with automated renewal options.
