Cloudflare sits in front of a large share of the web as CDN, DNS and DDoS protection, and its free plan is genuinely usable, which is how it got there. Paid tiers add WAF rules, analytics and support above that. Cloudflare, Inc. is listed on the NYSE and based in San Francisco, so traffic metadata is handled under American law.

CDNsun is headquartered in Prague, Czech Republic, founded in 2012, and operates as an EU-based provider under full GDPR compliance. With European ownership and a transparent pricing model, it serves as a sovereign alternative to US hyperscaler CDNs for EU publishers and streaming platforms.
Why choose CDNsun over Cloudflare?
The decisive argument is data jurisdiction. Cloudflare is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
CDNsun removes that overhead. As a Czechia-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
