Cisco Intelligent Multi-Scan - Product Details
IronPort Intelligent Multi-Scan incorporates multiple anti-spam scanning engines, including IronPort Anti-Spam, to provide an intelligent, multi-layer anti-spam solution. This method provides more accurate verdicts that increase the amount of spam that is caught but without increasing the false positives rate.When processed by IronPort Intelligent Multi-Scan, a message is first scanned by third-party anti-spam engines. IronPort Intelligent Multi-Scan then passes the message and the verdicts of the third-party engines to IronPort Anti-Spam, which assumes responsibility for the final verdict. After IronPort Anti-Spam performs its scan, it returns a combined multi-scan score to AsyncOS. Combining the benefits of the third-party scanning engines and IronPort Anti-Spam results in more caught spam while maintaining IronPort Anti-Spam's low false positive rate.
