About Transport Layer Security (TLS)
TLS secures emails transmitted over the internet using standard encryption technology. Securing emails this way reduces the risk of interception, eavesdropping and mail forgery.
TLS has proved to be a stable and reliable service that requires no intervention by the email sender or receiver once it is available on both parties’ mail servers. This means that both the sender and receiver can send and receive emails as they currently do today. For these reasons TLS is fast becoming the email security standard which many financial institutions, corporates and public email providers are planning to implement if they have not already done so.
For both incoming and outgoing email, the FMO mail server will attempt to set up a TLS secured connection with your mail server. If your mail server also supports TLS and a secure connection can be established, any information transmitted between the servers is encrypted, including the subject line, message text and any attachments. This is called Opportunistic TLS.
If you register your email domain details with us, we can implement a Forced TLS connection with you. Forced TLS ensures email is only sent if a secure connection is established between the mail servers.
Setting up a TLS connection with FMO
As TLS is configured on mail servers, you should contact your technology department to find out if TLS is already enabled. If not, ask your technology department to activate TLS if possible.
Once TLS is configured at your end, you can contact your FMO Relationship Manager with the email domains that should be listed with us and contact details for your IT representative. Your FMO Relationship Manager will forward these details to our IT department who will help with establishing and testing the Forced TLS connection with your IT representative.
