Site Seal

Site Seal

This certificate comes with the trusted Comodo Secure Site Seal, which is one of the most recognized seals online. Also, since this is an Organization Validated (OV) certificate, the site seal is dynamic, which means a user can click on it to see real-time, validated information about your company.



Since this is a Unified Communications Certificate, which comes with 5 total SANS, it does not come with a warranty. If you are looking for a multi-domain certificate that does come with a warranty, we would recommend the Comodo Multi-Domain SSL, although it is not designed to work exclusively with Microsoft Exchange.
