The Scan Profile and Settings Used for the Additional Websites

For more information about configuring and managing Scan Profiles in Acunetix 360, see Overview of Scan Profiles.

Setting the Scan Scope

The configured Scan Scope settings do not apply for the Additional Websites. Instead the Whole Domain scan scope will always apply. This means that all of the detected pages and sub folders on the additional website will be scanned.

For further information, see Scan Scope.

Including and Excluding URLs

The configured Include/Exclude URLs apply for Additional Websites too. So, if an additional website's links contain exit or endsession keywords, they will be excluded from the scan.

For further information, see Writing Regular Expressions to Include/Exclude URLs.

URL Rewrites

The URL rewrite configuration also applies for Additional Websites. If the Heuristic URL rewrite technology is used, the scanner will try to automatically identify the URL Rewrites on the target website. If custom URL Rewrite rules are configured, they will also apply to Additional Websites as well.

Therefore if an Additional Website contains a link that matches the pattern configured above, for example,, the URL Rewrite parameter(s) will be detected automatically.

For further information, see URL Rewrite Rules.


It is not possible to configure authentication settings for Additional Websites via the scan settings.

For further information, see Configuring and Verifying Form Authentication in Acunetix 360.

Reporting Scan Activity and Issues Identified in Additional Websites

The configured Additional Websites will have a node each in the Scan Summary list, as illustrated.

A new entry was also added to the reports, in which all the configured additional websites that were scanned will be listed.

The URLs in the reports are reported in full in the MIME Types node on the Knowledge Base tab, so that you can see which ones contain the issue.
