TLS, short for Transport Layer Security, is a protocol used for establishing a secure connection between two computers across the Internet. As an email provider we give our clients the best of security options, and TLS is a very important security tool. Our system gives our users the option to use TLS or SSL when connecting their email client (Outlook, Apple Mail, etc) to our incoming and outgoing servers for the purpose of encrypting the connection itself.
Enforced use of SMTP TLS is one of several methods that LuxSci SecureLine email encryption can use to ensure secure email delivery. See: How SecureLine Works. In particular, LuxSci SecureLine allows you to leverage TLS for secure email delivery, if you choose, via:
This TLS Checker is solely concerned with TLS in relation to the recipient of the email you send (SMTP); specifically whether the recipient's inbound email servers support "Opportunistic TLS". When our servers connect to the recipient's servers, they check to determine if TLS encryption is available. (See: How to Tell Who Supports TLS for Email Transmission).
By entering the domain of someone's email address and clicking on the "Check for TLS Support" button, you can determine if their inbound email servers are capable of using TLS. If you are using an email provider that enforces the same level of security that we do here at LuxSci then email sent to users in that domain should be automatically sent over an encrypted connection. This will make it so that your email communications cannot be eavesdropped upon.
Note that secure server-to-server communications should only use TLS v1.0+ (and not SSL v3.0) and should use strong ciphers (see NIST 800-52r1). This tool indicates domains that have TLS support but which are configured poorly so that they do not provide the option to use this level of encryption.
Every time I needed support with LuxSci's Secure Email solution the technical staff at LuxSci found the solution very quickly. They always get to work on a ticket immediately. They always give a status update in the ticket system which also notifies via email. Opening and updating a support ticket is very easy. We are very pleased with the Secure Email product and the support team."
