With these steps, we have significantly strengthened security and privacy for Comcast email users, though in the world of Internet security, our work is never truly done.
Upgraded our mobile email app – Xfinity Connect Mobile – to support TLS encryption. As of this writing, approximately 40 percent of all inbound e-mail from external domains to Comcast users is encrypted, and we expect that to rise as more email providers adopt STARTTLS.Įnsured that all outbound traffic sent to other domains is encrypted using STARTTLS (again, if the other domain supports it). Over the past year we have:Įncrypted our Xfinity Connect web interface to email, voicemail, and text messaging using TLS.Įnsured that inbound mail coming to Comcast customers from other domains (such as ) is encrypted using STARTTLS, provided that the sender’s domain supports encryption. In order for STARTTLS encryption to work the way it’s intended to, both the sender’s and the receiver’s email providers must support the technology.Įach time a new provider adopts STARTTLS, the security and privacy of the entire e-mail ecosystem improves. This allows for the encryption process to be completed seamlessly from one e-mail provider to another. An encrypted message looks like gibberish unless it’s translated using the right "key." TLS is deployed between our servers and email clients, including POP/IMAP clients like Microsoft Outlook, as well as our web-based Xfinity Connect client.īetween our servers and other domains we use STARTTLS – a global standard for encrypting e-mail using TLS between domains. The technology we use, Transport Layer Security (TLS), is used to encrypt the transmission of data over the Internet. The work we’ve done over the past year will ensure that the email messages our customers send and receive are encrypted as often as possible.
Email between our systems and other domains like and is encrypted as well, provided those domains support new email security protocols.Įncrypting your email makes it much harder for criminals – or anyone else – to see the messages you send and receive. This means that our web portal, which provides users with browser-based access to e-mail, voicemail and text messaging, now supports encrypted communications by default. We recently completed the critical step of encrypting the Xfinity Connect webmail interface. That’s why, for the past year, we’ve been working on strengthening the privacy and security of your Comcast e-mail account, and are proud to announce another important milestone. You need to know that your messages won’t be subject to snooping or be intercepted on the way to their intended recipients.
