Allow Lists - Securly Learn

Warning

Modifications to these settings can have a significant impact on the core filtering functionality.

Allow list type	Description
DNS allow list	Domains entered in this list can be used to entirely bypass Securly DNS, meaning that they will not be redirected to Securly servers for authentication or filtering.
Referer/Origin allow list	Domains entered in this list will have embedded content permitted based on the Referer or Origin HTTP headers. This is typically used when embedded content is restricted by a Filter policy.
User-Agent allow list	This list allows embedded content to be permitted based on the User-Agent HTTP header. This is typically used when embedded content is restricted by a Filter policy or when applications (particularly on iOS) that generate web traffic need to bypass Filter to function properly.
Referer/Origin allowed destinations	This list is used in combination with the Referer/Origin allow list or User-Agent allow list to restrict the domains that can be embedded. This restricts embedding to youtube.com ad/or Vimeo.com so that embedded social media feeds are not accessible.
