WAF for multi-level subdomains

Hi there, I am looking to purchase the Business plan but I was just wondering whether the WAF product can be used on a multi-level subdomain, e.g my.long.subdomain.domain.com? And if so can have I as many sub-domains as I wish?

Generally yes, the WAF does cover the entire zone as long as it’s proxied (orange cloud for the DNS records :orange:).

The only thing you need to worry about is SSL for these subdomains. On the business plan you can only upload a single custom certificate.

So if you want something.else.example.com and my.long.subdomain.example.com SSL protected your certificate will need to include both hostnames (or both wildcarded to the second subdomain like *.else.example.com and *.long.subdomain.example.com) and you’ll need this for each hostname you want.


Thanks @Judge. In relation to the SSL, I’m guessing I can also use the Cloudflare Dedicated Certificate with Custom Hostname? https://support.cloudflare.com/hc/en-us/articles/228009108-Dedicated-SSL-Certificates

Yes, using that will also work :slight_smile:
