Is TLS good enough for secure email?

When it comes to collecting sensitive customer data, you simply cannot afford to take any chances. Your customers trust you and you need to protect them – and their most-personal details. But, while protecting your digital perimeter is important, your organization also needs to ensure sensitive data stays secure during transit.

One way to do this is to leverage a TLS encryption solution. But what exactly is TLS? How does it work? And when is it good enough for secure email?

Here’s what you need to know about TLS:

What is TLS?

In layman’s terms, TLS, short for ‘Transport Layer Security, is a method of encrypting the connection between two parties communicating over the Internet – think of an encrypted tunnel. TLS can be applied to email to prevent unwanted eyes from viewing messages in transit – or from accessing data transmitted between a user and a website. The ease of this type of message encryption makes it one of the more popular types of delivery methods.

When is more message security needed?

TLS is one of the most primary and simple methods of delivering secure messages. But is it secure enough? It depends – you tell us.

Do you have access to alternative encryption methods if a TLS connection is not available? What exactly are your security needs? Are you worried about third-parties, like Google via Gmail, scanning your correspondence? Are you worried about man-in-the-middle attacks, where a secure connection is compromised? These are just a few of the questions you need to address when determining whether TLS is secure enough for you.

How do you get more message security?

While regular TLS-encrypted messages do have their benefits, this delivery method doesn’t always meet every one of your customers’ needs. That’s why Echoworx OneWorld goes further, automatically offering more encryption delivery methods. OneWorld also offers flexibility within the TLS environment – with the ability to create specific policies for using TLS and branded email footers highlighting that a message was delivered securely.

Are there secure alternatives to TLS?

In instances where TLS is not desireable you need to have other options – to ensure no message goes out unencrypted or to a compromised environment. And there are a variety of other secure delivery options available, from public key encryption methods, like S/MIME and PGP, to Secure Web Portals.

Echoworx’s OneWorld encryption platform offers all these options, as well as encrypted attachments. And, since OneWorld checks to see if TLS is available before transit, sensitive messages are never sent unencrypted.
