Paubox will be disabling TLS 1.0 beginning 1 December 2017. We are doing this to align with industry best practices for security and data integrity. While we pride ourselves in our military grade encryption, we also pride ourselves in user experience. No action is required prior to this date - simply continue using your encrypted email service from Paubox as you normally would. TLS 1.1 will be the new minimum standard security protocol Paubox implements in order to align with industry-wide best practices for security and data integrity.
TLS, short for Transport Layer Security, is an encryption protocol that protects messages in transit from one server to another. The encryption protocol deploys whenever a web browser or application transmits data over a network. All Paubox network traffic, whether it contains PHI or not, is encrypted using industry-standard transport encryption (TLS). TLS prevents emails from being read while in motion and ensures the communication is delivered to the appropriate recipient. Currently, TLS has three versions: TLS 1.0, 1.1 and 1.2.

The upgrade will begin on 1 December 2017. The transition will occur "behind the scenes," so you will not need to change how you normally use Paubox. After December 1, TLS 1.1 and above will become the standard TLS version for Paubox Email Suite.
The impact will not affect most users. In fact, most users won't notice. However, in the unlikely case that you experience any interrupted access to your Paubox account or encrypted email service, contact us at support@paubox.com.
