Key Features
SenderBase Reputation Filtering
Ironport Reputation filtering uses intelligence from a global intelligence
network to identify senders of spam mail and block them from being able to
send mail into your network. The input into Senderbase is taken from
honeypot email addresses, ISP data, blocklists and other sources, and
analysing the data and content of the emails (e.g. spammed out Phishing
links) allows Ironport to identify rogue IP addresses and filter them out.
Ironport
Anti Spam
Once the mail is accepted into the system, Ironport anti-spam performs a
further Bayesian analysis of message content to screen out any remaining
spam messages based on content analysis.
Antivirus
All emails received are checked for viruses using a Sophos antivirus engine.
Zero Day Virus Protection
Ironport have a partnership with Sophos which enables them to provide you
with protection in the early stages of a virus outbreak by quarantining
potentially virus infected emails until antivirus definitions are released.
At this point, the quarantine is released for processing.
Identity Based Encryption
Ironport provide an option of Identity Based Encryption which enables email
to be sent securely without the use of specialist encryption software. The
email is encrypted using the recipient’s email address as their public key.
The user then authenticates against a hosted key server to view the secure
email message.
Email Attack Mitigation
The underlying secure operating system on Ironport appliances (AsyncOS)
provides protection against common email attacks such as directory
harvesting, email bounce attacks, and mail relay
