Cisco Cisco Email Security Appliance C390 入门指南

Features Galore

Cisco Business Class Email features are detailed in Table 1.

General Features - Descriptions

Confidentiality

Cisco Business-Class Email uses the most reliable email encryption 

algorithms available. The solution not only encrypts data to protect 

its confidentiality while it travels through the network, but also 

applies the latest authentication mechanisms to make access to the 

encryption key easy and secure.

Seamless user 

authentication

The solution uses Security Assertion Markup Language (SAML) to 

authenticate and verify the identity of email recipients - enabling 

Cisco to provide strong authentication while retaining ease of use 

for recipients. Once users are registered with the SAML gateway, 

they can use their corporate login credentials to access encrypted 

emails as easily as they access other company resources.

Enhanced email 

controls

Secure messaging enables Cisco to provide new email controls 

for users. Encrypted emails ensure the information sent remains 

confidential. In addition, they enable the sender to expire or recall 

an email and know exactly when the email was opened. 

Security Features - Descriptions

Read receipt

When a recipient opens a message ― after a user is successfully 

authenticated and the recipient receives the encryption key ― Cisco 

ensures the information was read and delivers a read receipt to the 

sender within seconds.

Guaranteed 

message recall

When the sender selects the recall option, the key to decrypt 

the data expires, making it impossible for anybody to access the 

content of the message.

Message 

expiration

Enables the sender to set an expiration date for the message. After 

the expiration date has passed, the encryption key will be disposed 

of, making the information inaccessible.

Control over 

forward/reply

Provides advanced controls over what can be done to an email 

message once it has been received. Forward, Reply, and Reply 

commands can all be disabled or enabled only if the sender’s 

company authorizes them.

Outstanding 

receipient user 

experience

Recipients can securely reply to, reply to all, or forward those 

messages, regardless of whether the recipient has encryption 

enabled or not.
