Is Google's Cloud DNS product a competitor? https://cloud.google.com/dns/

Doesn't seem like it has the "firewall" capabilities of CF.

Because of the size of the WordPress market, Sucuri.net might be a legit competitor.

You are mostly listing CDNs and/or DNS services. None of which are "competitors" to what Cloudflare is offering.

Akamai and Incapsula are the only real competitors and, tbh, none of them are particularly "good" which is why CloudFlare has been so successful.

Sucuri is fine for a corporate blog or the like but it just really isn't usable for a high traffic site with alot of dynamic content.

Curious why you say that of Sucuri? Have you tried us recently?

We have some very very large sites using our services now with great performance. During the last 6-12 months we basically rewrote our entire stack, built our anycast network and focused a lot on performance optimization and expanding out services.

You can ping me directly if you prefer too.

thanks!

I haven't used it in the last 8 months, so its quite possible this stack rewrite leads to reasonable performance.

However, I'm not going to try it on a production website to see.
