Once access to the decrypted message is obtained, the recipient has the ability to securely Reply, Reply All
(configurable), and Forward (configurable), without requiring any special software.
WatchGuard Email Encryption provides enhanced security to keep unwanted eyes from viewing the
document after it has been opened by requiring that the decryption key be retrieved from the server each
time the message is read, allowing message to be locked by the sender even after they have been read.
The Message Decoding Process
Messages are encrypted using either AES or RC4 (both highly secure) industry standard algorithms. The
HTML attachment in the notification contains the encrypted message content, as well as JavaScript to
decrypt it locally, thus eliminating the need to install special software and enabling the solution to have
universal reach with high usability.
In some cases, JavaScript is not always available. It may be stripped out at the receiving gateway or disabled
in the recipient’s browser. This does not hinder a recipient from easily decoding encrypted messages. CRES
technology performs the encryption over a link secured with the SSL protocol. Once the recipient enters his
or her valid password, the encrypted message is automatically posted to CRES for decryption. The
decrypted message is then sent back to the recipient’s browser for display. Although this method of
decrypting messages is slower and less scalable than decoding them locally, it is a viable alternative when
JavaScript is not available.

ENCRYPTED MESSAGE TRACKING AND REPORTING
WatchGuard Email Encryption’s web-based interface allows users and administrators to track messages and
run reports on encrypted message activity, including:
Delivery & Response Tracking
When an encrypted message is opened, notifications are sent to the server and read receipts can be
optionally generated for senders. Administrators can also configure time-based triggers to track when a
message is opened and to signal when they have not been opened within a specified period of time.
Message Activity Reporting
WatchGuard XCS provides extensive content filtering reporting capabilities. Administrators can generate
reports which indicate how many messages were flagged by each pre-defined policy and can also generate
reports by user, as well.

CONCLUSION
The WatchGuard Email Encryption solution is the most comprehensive and easy-to-use tool for keeping
confidential information secure and avoiding embarrassing and potentially damaging and costly data
leakage caused by user errors or oversights.
The WatchGuard Email Encryption solution provides maximum security to organizations and its users with
its transparent encryption capabilities using custom or pre-defined policies, data loss prevention, and
compliance dictionaries. Also, since messages are never stored on the same server as their keys, the
WatchGuard Email Encryption solution ensures that only those with permission to view the encrypted
message have access to its content.
Organizations concerned with compliance to both industry regulations and internal corporate policies can
confidently rely on WatchGuard Email Encryption in correlation with the WatchGuard XCS to scan outbound
messages with its powerful Data Loss Prevention and take the appropriate remediation, including blocking,
quarantining, or automatically encrypting messages containing confidential and sensitive information in
accordance with corporate policies. Using a policy-driven approach which can easily be extended and
customized to meet individual needs for controlling confidential data, the WatchGuard Email Encryption
