Custom Block Lists
Block or allow the assets you want your endpoints to resolve on the Internet.
Domain block/allow lists allow administrators to block or accept by tld, hostname, or registered domain name.
Network block/allow lists enable administrators to immediately block or allow any domain resolving to the networks they specify.
If you wanted to block domain resolution to a /8 CIDR block, you can. If you choose to override a domain we’re blocking in a category, you can. You’re always in 100% control of what gets accepted or blocked.
