Browser Security Notice:
Internet Explorer 5.0, 5.5 and 6.0 SSL Vulnerabilities

Summary: A security vulnerability has been discovered in Microsoft's Internet Explorer (IE) browser that could cause an SSL server certificate to be trusted even if not directly signed by a legitimate Certificate Authority (CA). This flaw could allow a malicious site to "forge" an SSL server certificate under any name it chooses, once it had obtained a legitimate certificate from a trusted CA.

The vast majority of current browsers will connect seamlessly to sites secured with an Entrust SSL Certificate. See the table below for details.
