Cloudflare Integration

Your site, faster
and more secure with Cloudflare.

Cloudflare sits in front of your hosting (o2switch, OVH or other) to speed up loading worldwide and block malicious traffic before it reaches your server. I configure CDN, WAF, DNS and cache rules for a faster, more resilient site, without changing anything about your current hosting.

Cloudflare rend trois services distincts qu'on confond souvent : accélérer le site en servant les fichiers depuis un point proche du visiteur, le protéger des attaques et du trafic automatisé, et gérer le DNS. Mal réglé, il fait aussi des dégâts : cache trop agressif qui sert une page de connexion à tout le monde, règles de sécurité qui bloquent votre propre back-office, ou compression qui casse un script. Je configure les règles de cache selon ce que le site sert vraiment — statique agressif, HTML prudent —, le pare-feu applicatif, et les certificats.

C'est souvent le levier de performance le plus rentable sur un site déjà en ligne.

FAQ

Frequent questions

Does Cloudflare replace my o2switch/OVH hosting? +
No, Cloudflare sits as an additional layer in front of your existing hosting. Your site continues to be hosted at o2switch, OVH or elsewhere; Cloudflare filters and speeds up traffic before it reaches your server.
How much does setting up Cloudflare cost? +
Full configuration (DNS migration, WAF, cache rules): €400 to €900 as a one-off service. The Cloudflare Free plan is enough for most SME e-commerce sites; the Pro plan (~€20/month) adds advanced WAF options.
Can Cloudflare break my site during migration? +
The risk is very low with a careful migration: I systematically check every DNS record before switchover and test all critical journeys (payment, forms) right afterward.
Can the WAF block real customers by mistake? +
That's a risk with poorly calibrated configuration. I configure rules progressively ("Log" mode before "Block"), monitor false positives during the first few days, and adjust. A well-tuned WAF blocks threats without ever inconveniencing a legitimate customer.
