Frequently Asked Questions
Quick answers on onboarding, performance and protection.
How is SCDN different from a regular CDN?
SCDN integrates enterprise security on top of CDN acceleration — DDoS protection, WAF and bot management unified, no extra security appliances.
Will SCDN affect site performance?
No. Security checks run in parallel at the edge, adding under 1ms; smart caching and protocol optimization make the site faster overall.
How large an attack can you mitigate?
15Tbps+ global scrubbing capacity; largest single attack scrubbed to date was 3.2Tbps. Capacity scales elastically beyond plan limits.
How quickly can I get started?
One CNAME change — live in 5-30 minutes, no origin rework. Enterprise customers get a dedicated architect.
Do you support HTTPS and custom SSL?
Yes. Free certificates issued and renewed automatically, custom certificates supported, full TLS 1.3.
