What is TLS Encryption?
Transport Layer Security (TLS), is a way to encrypt your email traffic from server to server. It bypasses the complicated time drain that is per email encryption, while still ensuring security. TLS is a minimum requirement for e-security best practice.
To implement TLS, identify what email server you’re using and if the server can enable TLS (the vast majority will). If your server allows it, enable TLS. From this point, the emails will be sent and received using TLS as long as the destination has TLS enabled on their server.
If the destination server is not TLS enabled, your email will not be encrypted when sent and will be left vulnerable to attacks.
Policy based TLS encryption services allow companies to ensure email is only sent to certain organizations if TLS encryption is applied. These secure encrypted connections essentially create a private network for the company.
Other Types of Encryption
TLS encryption is only one step in securing your email but it is the best place to start. However, companies should be aware of the other end to end or push to pull encryption options and the more important layers such as
E-security best practice calls for companies to ensure the most appropriate level of encryption should be enabled. The variety of email encryption options available allows corporations to choose the best fit for their business and needs. See below for a complete list of options and further explanation on SPF (Sender Policy Framework), DMARC (Domain-Based Message Authentication, Reporting, and Conformance), DKIM (DomainKeys Identified Mail), and other encryption options.
