Tamper Detection Policy Configuration

Description

Tamper Detection is a policy you configure within a policy set. It checks whether a sender changes or completely removes their Exclaimer-managed signature before they send an email, after they send it, or both, depending on how you configure it.

How to access it

To access your policy sets:

1. From the menu sidebar, select Tamper Detection. 

   The Tamper Detection page displays your existing policy sets, along with the senders and configuration each one applies to.
    

2. Select Edit policies on the relevant policy set you wish to configure.
   
   
   _{Select Edit policies.}
    

Configure Tamper Detection

To configure Tamper Detection for a policy set:

1. Click the policy name to edit it. 
   
   
   _{Select the pencil icon to edit the policy name.}
    

2. Under Signature: Tamper Detection, select the relevant checkboxes:
   
   • In Pre-send, select Analyze signature and show warning to enable client-side detection through Outlook Add-in. 

   • Select Block email from being sent to stop the sender from sending an email when they have changed or removed their signature.  

   NOTE: If an email signature has been tampered with, Outlook will display a warning advising you not to send the email because it does not comply with company policy.
   
   _{Outlook will display a warning advising you not to send the email.} 

   • In Post send (Server-side), select Analyze signature to check for tampering on the server after the email is sent.
   
   Post send checks record a policy violation, whether the signature was modified or is missing entirely, without interrupting mail flow. Administrators can review all recorded policy violations in the Tamper alerts.
    

3. Select the Enable toggle to turn the policy set on.
   
   
   _{Select the Enable toggle to turn the policy on.}
