Description

With the release of SonicOS 7.1, Reputation-based web filtering is possible in the CFS 5.0. Reputation-based web filtering feature will allow SonicWall to Allow/Block access to websites based on the reputation score of the websites.

Reputation-based filtering provides a score that forecasts the security risk of a URL. Reputation score is an integer value between 0-100. The higher the value, the safer the URL is.

The reputation score is divided into Six categories as displayed in the following table:

Threat Reputation	Score level
High Risk	1-20
Suspicious	21-40
Moderate Risk	41-60
Low Risk	61-80
Trustworthy	81-100
URL without Reputation	0
