Exclude subdomains and customize the OWASP ZAP crawler

ZAP scans every subdomain that its crawler finds. Edit the crawler settings of a target to choose which domains, subdomains, and URLs to scan.

Last updated on 19 Oct, 2026

HostedScan’s default settings include all subdomains discovered in the ZAP scan. For example, when scanning https://mysite.com both https://mysite.com and https://blog.mysite.com would be included in the scan. However, in some cases there is noise from including all the subdomains, especially if some properties are outside of the user’s control. For example, if a blog is hosted by a third-party vendor.

With HostedScan, you can fully customize the scope of the scan to precisely control which domains, subdomains, and URLs are included in the scan. Follow the steps below:

1. On https://hostedscan.com/targets - click to edit the desired target
