What is TLS Encryption?

Email services such as Gmail and Outlook continue to reign supreme in day-to-day business communication. While vanilla text exchange (unencrypted email) is by far the most popular in traditional email applications, this model drawback leaves users vulnerable to data breaches and ransomware attacks.

Transport Layer Security (TLS) or TLS Encryption helps secure email messages both in storage and in transit so that your messages don’t travel through open mail servers. Instead, they are sent through a secured email server that helps to prevent eavesdropping from online hackers.

Just as TLS can be employed to protect a website (HTTPS) the same applies to email communication. To maximize the full power of TLS Encryption both the sender and recipient must have it enabled otherwise the content from within the email could still be compromised. In other words, both the internal and external servers that handle the message require TLS in order to be secured.

What Features Does TLS Include?

While TLS Encryption may not be the “one-size fits all” solution if everyone uses it, eavesdropping on messages will be a whole lot harder.

Important features of TLS include:

1. Encrypted Email
– Public Key Infrastructure (PKI) is commonly used in TLS to encrypt email messages from both the internal and external servers making it more difficult to snoop on email messages.

2. Authentication
– Validating that the email message has reached its intended recipient greatly reduces fraud and helps to confirm that both the sender and recipient are who they say they are.

Conclusion

If you own or operate a business that deals with the sending and receiving of sensitive information, TLS Encryption may not be your best option. Instead, you may want to think about partnering with a third-party encryption service such as NeoCertified. NeoCertified offers HIPAA-compliant email solutions and integrated features so you don’t even need to leave your email browser to send and receive secure email messages.
