Get a list of SharePoint sites that allow anonymous authentication

For administrators who manage (usually) public-facing SharePoint farms, it’s good to keep tabs on the sites that allow anonymous users. Configuring anonymous access is a multi-step process — there are web application settings, site settings, and permissions. Although there is a lot of configuration, it’s easy to see which sites allow anonymous authentication using the SPWeb.AnonymousState site-level flag. Using this property we can write a short PowerShell script to list out all the sites in the farm and display whether or not they allow anonymous authentication.

SharePoint 2013 and SharePoint 2010

For SharePoint 2010, SharePoint 2013, and presumably future versions of SharePoint, getting this list is simple using the Get-SPSite cmdlet which can be used to list every site collection in the farm:

$sites = Get-SPSite -Limit All
foreach ($site in $sites) {
	$site.AllWebs | Select Url, AnonymousState
}

The output will look like something like this:

Url                                         AnonymousState
---                                         --------------
http://example.com                                 Disabled
http://example.com/searchcenter                    Disabled
http://example.net                                      On
http://example.net/About                                On
http://example.net/Careers                              On
http://example.net/Contact                              On
http://example.net/Search                               On

SharePoint 2007

If you have PowerShell installed on a server in the farm (you really should), you can use PowerShell to build this handy report just it takes a bit more effort:

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
$farm = [Microsoft.SharePoint.Administration.SPFarm]::Local
$websvcs = $farm.Services | where -FilterScript {$_.GetType() -eq [Microsoft.SharePoint.Administration.SPWebService]}
$webapps = @()
foreach ($websvc in $websvcs) {
	foreach ($webapp in $websvc.WebApplications) {		
		foreach ($site in $webapp.Sites) {
		
			$Site.AllWebs | Select Url, AnonymousState
		
		}
    }
}

The output will look look the same as with later versions of SharePoint:

Url                                          AnonymousState
---                                          --------------
http://example.com                                 Disabled
http://example.com/searchcenter                    Disabled
http://example.com/sites/Example                         On
http://example.com/sites/Example/Site1                   On
http://example.com/sites/Example/Site1/SubSite           On
