Simplified Messaging Security through a Cloud-Based Encryption Service

The Cisco® Registered Envelope Service is the most advanced cloud based-encryption key service available today. Whether you need to meet compliance requirements, secure customer and partner communications, or protect intellectual property, the Cisco Registered Envelope Service provides a flexible and scalable solution to help you support your secure messaging requirements without having to invest in additional infrastructure.

Although regular emails are not a secure communication medium, encryption and key management is often seen as too complex to be used in everyday communications. The Cisco Registered Envelope Service takes away the complexity behind encryption and makes it seamless for senders and recipients to exchange secure messages.

The Cisco IronPort Difference

Cisco IronPort® email and web security products are high-performance, easy-to-use, and technically innovative solutions, designed to secure organizations of all sizes. Purpose-built for security and deployed at the gateway to protect the world’s most important networks, these products enable a powerful perimeter defense.

The Cisco IronPort line of appliances is smarter and faster in part because they take advantage of Cisco Security Intelligence Operations center and global threat correlation. This advanced technology enables organizations to improve their security and transparently protect users from the latest Internet threats.

Features

Secure Delivery Methods

The Cisco Registered Envelope Service offers a wide range of options for secure message delivery, and can support any email encryption requirement.

Cisco IronPort Encryption is a highly secure, envelope-based “push” technology that combines universal reach, ease of use, and the lowest total cost of ownership (TCO) of any email encryption technology. Encrypted messages can be received by any email user - independent of the email client, the operating system, or the device used - without the need to install any software or requiring the sender to preexchange encryption credentials with the recipients.

Business-Class Email

In addition to securing email content, Cisco IronPort Encryption technology enhances visibility and control over email.

Guaranteed read receipts enable users to know exactly when a message was viewed by each recipient.

Message expiration and recall prevents mistakenly sent messages from being opened and automatically secures old messages. The message may be recalled at any time, keeping the message from ever being opened again.

Authentication and key delivery typically occurs by identifying user credentials. When a recipient has been successfully authenticated, the key for that message is released and the recipient gets access to the message.

Enrollment management is enabled for first-time recipients as they are guided through a single-screen enrollment to create an account on the key server. This account may be used to receive any future messages.

Security Assertion Markup Language (SAML) 2.0 gateways integration is an advanced feature enabling organizations that have implemented an identity gateway to use their existing investment with Cisco Registered Envelope Service. Recipients of an encrypted envelope will be able to use their corporate credentials to authenticate with and decrypt the message automatically. This integration removes the need for first-time recipients to create a new account on the service and makes it very easy to access secure messages using their corporate username and password.

Universal device support guarantees that secure messages can be read by any recipient regardless of the device they use to open the message. Dedicated plug-in applications offer an enhanced user experience for Microsoft Outlook and on Apple iOS and Google Android smartphones.

Message management is provided as part of the business-class email features and includes message recall and expiration and guaranteed read-receipt. These features can be accessed through the Cisco Registered Envelope Service web interface or directly from the email client by installing dedicated plug-ins.

Hosted Key Server

The Cisco Registered Envelope Service manages recipient registration, authentication and per-message encryption keys. Figure 1 shows how the Cisco IronPort Email Security Appliance and Cisco Registered Envelope Service interact. The Cisco Registered Envelope Service works with Cisco IronPort C-Series email security appliances, encrypting and decrypting messages based on policies defined on the Cisco IronPort C-Series.
