We get attacked several times a month, we rely on Cloudflare & Corero to mitigate attacks.
Cloudflare handles HTTP/s attacks and Corero handles network level attacks.
Both require tweaking and are far from being 1-click setup tools (despite some marketing attempts that try to make it seem that way), however, if you can manage them, they are very powerful and considerably cheaper than other alternatives.
Thank you, I didn't know about Corero, will check them out. CF we use, and as you said, they are a tool. Plenty of ways they could be better, but they are still the best (in moderate price range) we know.
