The most effective way to protect your server is by placing infrastructure in front of it. Relying solely on your hosting provider’s mitigation is not the best approach because, like OVH, they can sometimes block legitimate clients during mitigation events.
A better solution is to use proxy servers combined with Cloudflare to distribute traffic across multiple proxies. fiveshield.co does this very well, and it becomes even more secure when used with an OVH origin server thanks to the network edge firewall rules they provide.
