Email Encryption

Despite the rise in text messaging, instant messaging, social networking, and other forms of communication, email continues to be the predominant business collaboration tool. But the unsecure nature of email has resulted in the inadvertent and malicious exposure of sensitive information.

Technologies to encrypt email, such as S/MIME and Open PGP, have been available for several years, but they have failed to achieve widespread adoption. The limited use of these technologies is primarily due to their deployment complexity and the burden they place on the sender and the recipient to open and manage encrypted messages.

Cisco IronPort Email Encryption overcomes the problems of earlier encryption technologies by providing a solution that that meets compliance requirements for email encryption, while delivering powerful new email control features—all in an easy-to-use, broad-reaching, and affordable offering.

Cisco IronPort Email Encryption

Features:

Integrated Functionality

Along with RSA Email DLP, Cisco IronPort Anti-Spam, and Cisco IronPort Virus Outbreak Filters, Cisco IronPort Email Encryption is integrated into the high-performance line of Cisco IronPort email security appliances. Converging email functions into a single appliance means a simpler email infrastructure and lower capital and operational costs.

Flexible Sender Encryption

The sender can initiate encryption through a wide variety of means, including installing an email client plug-in that allows them to encrypt a message with the click of a button, marking the message as urgent, or using a code word (such as "encrypt") in the subject line. Emails can also be encrypted automatically through administrator-configured policies.

Support for All Email Platforms

Messages encrypted using Cisco IronPort Email Encryption can be opened by any AOL, Yahoo!, Gmail, or Hotmail user, as well as by traditional enterprise email clients such as Outlook, Lotus Notes, and Groupwise.

Flexible Key Management

Cisco takes the burden out of encryption key management through a hosted key management service. The Cisco Registered Envelope Service provides secure and transparent management of encryption key creation, distribution, and retention. Operating from multiple Cisco data centers, the service has high availability and 10-year key retention. If an organization cannot permit a hosted key service, Cisco provides the flexibility of on-premises key management with the Cisco IronPort Encryption Appliance.

Benefits:

Easy to Set Up and Administer With Cisco IronPort Email Encryption, email administrators can implement message-level encryption in two easy steps and be up and running in minutes. Cisco transparently manages key creation, distribution, and retention, as well as recipient user management.

Total Email Control Unlike other email encryption solutions, Cisco IronPort Email Encryption allows the sender to continue to remain in full control of their content—even after it's been sent. With Cisco IronPort Email Encryption, senders don't have to fear mistyped recipient addresses, mistakes in content, or time-sensitive emails, because they always have the option to lock the message.

Regulatory Compliance Cisco IronPort Email Encryption satisfies the encryption requirements for regulatory requirements such as PCI, HIPAA, SOX, GLBA — as well as state privacy regulations and European directives—without being a burden on the senders, recipients, or email administrators. Ease of use combined with powerful features means that now IT can offer encryption as a service, not a mandate.

Summary

Cisco IronPort Email Encryption technology revolutionizes email encryption—satisfying compliance requirements while providing opportunity to extend into areas that can add tangible business value. Cisco provides the only email encryption technology that combines universal accessibility (send and receive on any email platform) with ease-of-use (no client software or PKI), and is proven in mission-critical deployments of up to 30 million recipients.
