Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

IronPort Anti-Spam filtering is based on Context Adaptive Scanning Engine 
(CASE) ™, and is the first anti-spam scanning engine to combine email and web 
reputation information to:

Eliminate the broadest range of email threats — detect spam, “phishing,” 
zombie-based attacks, and other “blended” threats.

Deliver the highest accuracy — anti-spam rules based on email and web 
reputation from SenderBase Reputation Service.

Offer ease of use — due to reduced hardware and administrative costs.

Deliver industry leading performance — CASE uses dynamic early exit 
criteria and off-box network calculations to deliver breakthrough 
performance.

Address the needs of international users — IronPort Anti-Spam is tuned to 
deliver industry-leading efficacy world-wide.

CASE combines content analysis, email reputation, and web reputation to deliver 
the broadest set of threat prevention factors.

IronPort designed IronPort Anti-Spam from the ground up to detect the broadest 
range of email threats. IronPort Anti-Spam addresses a full range of known threats 
including spam, phishing and zombie attacks, as well as hard-to-detect low 
volume, short-lived email threats such as “419” scams. In addition, IronPort 
Anti-Spam identifies new and evolving blended threats such as spam attacks 
distributing malicious content through a download URL or an executable. 

To identify these threats, IronPort Anti-Spam uses the industry's most complete 
approach to threat detection, examining the full context of a message-its content, 
methods of message construction, the reputation of the sender, and the reputation 
of web sites advertised in the message and more. Only IronPort Anti-Spam 
combines the power of email and web reputation data, leveraging the full power 
of the world's largest email and web traffic monitoring network — SenderBase — 
to detect new attacks as soon as they begin.
