work with any email client (Outlook, mobile, etc.,) using specialized plug-ins which allow for
the means to send messages and attachments of any size and type securely and
transparently. The sent attachments should be stored in encrypted form within the internal
network, and only a download link should be sent to the recipient, thus ensuring the highest
level of security and privacy for shared files.

A good, advanced, email encryption solution is a solution which allows for sending secure
emails without disrupting the normal routine of the sender or recipient. It also allows both
parties to continue to work with their familiar email clients, while guaranteeing secure
delivery and receipt of emails and attachments.

For organizations who do not wish to deploy specialized plug-ins, some solutions offer their
own centralized SMTP gateway. Such gateways allow monitoring and handling incoming
and outgoing email messages. Once the gateway receives an email message, it scans the
message attributes, including the message subject, body, header, attachment type, and size;
then, based on pre-defined rules, it performs the required action: encrypt, drop, forward, etc.

Lastly, IT should also look at solutions which allow for automatically enforcing security
policies on outgoing and incoming emails. Outgoing emails should be authenticated,
scanned with a data loss prevention (DLP) solution, and encrypted to ensure only approved
data is shared securely. Incoming emails should be authenticated, scanned for viruses and
malware, and decrypted.

Using the solution described above, IT teams can empower engineering departments to
securely send their large design files (e.g. AutoCAD) to manufacturing departments or
external contractors using encrypted emails.
