E-mail should not be used for the exchange of confidential data such as personal information without encryption. But why should you encrypt internal e-mail exchange as well and how is it done in practice?
Why should the company’s internal e-mail exchange be encrypted?
Typically, a company’s own e-mail solution is thought of as being a safe place to store all internal e-mail exchange. Sometimes the e-mail is used to send such a sensitive information that storing it in an outsourced e-mail service or servers raises alarm for the person in charge of data security.
Does the service provider agreement also cover situations where sensitive information has ended into places where it does not belong? How many e-mail service admins have access to the e-mail data?
More and more of our customers are asking how to secure e-mails on the internal network or in an outsourced cloud service.
How is the internal e-mail traffic protected in practice?
In practice, the most reliable way to protect the e-mail messages is to use strong encryption already when sending a message by encrypting the data in the sending workstation and delivering the encryption key to the recipient in some way, who then opens the encrypted message in their own workstation when reading the e-mail.
This kind of protection has been used for years now, but unfortunately the distribution and management of encryption keys has proven challenging and has often been the problem that has prevented the usage in larger scale. These challenges raise their head especially in ad hoc -type of needs, where encrypted e-mail messages are needed to be delivered to recipients without any special preparations such as installing mutually agreed upon software or delivering encryption keys.
How does Deltagon's solution work?
The virtual S/MIME -service of Deltagon’s solution safeguards confidential messages between internal users and Sec@GW server and enables message encryption in the workstation of the sender. When sending an e-mail, user will utilize the standard S/MIME functionality of the e-mail software for message encryption or the Sec@GW Outlook plugin.
When delivering a message from the server to the recipient, Deltagon's familiar and straightforward notification message is utilized, which guarantees the delivery of a secure message to the recipient.
- The use of certificates as additional protection does not affect the recipient's user experience.
- E-mails are stored securely in the e-mail servers, encrypted with the senders personal keys.
