Explanation

Block all URLs to except for test.domain.com. Cisco Umbrella uses syntax where a "!" (exclamation mark) negates a specific entry in a block list. This allows test.domain.com while blocking all other subdomains of .domain.com. Configuration breakdown: 1. Block list: !“test”.domain.com: This negates the block for test.domain.com and ensures it is allowed. 2. Allow list: test.domain.com: Explicitly allows test.domain.com. 3. Block list: .domain.com: Blocks all other URLs under .domain.com.
