Security Notification:
Endicia no longer supports SSL 3.0


Dear Endicia Customer,

As part of our ongoing efforts to enhance security and protect your sensitive data, Endicia will no longer support the use of Internet security protocol, SSL 3.0. Starting on Monday, June 29 at 9:00am PDT, Endicia will require the use of the Transport Level Security (TLS) protocol to establish SSL connections.

Since the TLS protocol is widely used by newer web clients and operating systems (OS) for securing SSL connections, we do not expect this change to cause any connectivity issues for our customers.

Endicia has created a test URL https://validate.endicia.com you can use to verify your connectivity against the enhanced security settings. Cut and paste this url into your browser; you should see the message: "Success! Your client is compatible with Endicia's new SSL settings." If you do not see this message you will need to update your web client / operating system.

The following is a list of well known web clients and OS versions that support TLS and will continue to be supported by the Endicia software. If you are using a web client or OS other than the ones listed below, you may need to perform an update in order to continue printing postage through Endicia.
