In Ancoris Signatures, you can include any text you wish in a Signature Template and there is enough space to include compliance footer information.

However, we do not recommend you use Ancoris Signatures to manage compliance footer information as it is inherently static information as opposed to typical signature information which is personalised for each user.

In G Suite, you can manage compliance footer information, per Organisational Unit, directly from the Admin Console.
