Despite the rise in text messaging, instant messaging, and social networking, email continues to be the predominant business collaboration tool. The unsecured nature of email, however, exposes sensitive information to malicious attacks. The Cisco Secure Email Encryption Service (formerly Cisco Registered Envelope Service) provides enhanced security and reliable controls for traditional email tools. It is fully integrated into most common email technologies and into a user's daily email routine. Encryption is triggered by policy or by data loss prevention tools. Cisco Secure Email creates an encryption key then wraps the email in an HTML envelope and delivers it to the recipient. When Envelope Storage is enabled, the key and message are stored temporarily in the Secure Email Encryption Service. The recipient clicks on the link to open the message on any device. Secure Email Encryption Service is based on technology that uses the most reliable email encryption algorithms available.
