Selecting a Security Solution Advanced Network Protection
The following table offers some guidelines for estimating the performance each UTM Firewall will
experience under each scenario described above.
URL Filtering or Web Control?
URL Filtering and Web Control are two services that govern which websites users are allowed to
access. The two services work in quite different ways, and therefore have different effects on
performance.
URL
Filtering
URL Filtering is a stream-based service. URLs are filtered using either a user-defined list (in which up
to a thousand blacklist and/or whitelist URL entries can be configured), or a downloadable list
(consisting of many thousands of known malicious website URLs) that can be frequently updated,
obtained via Subscription.
URLs are extracted from GET, HEAD, POST, PUT, and DELETE HTTP requests for matching against
white lists and black lists in real time. URL Filtering might be used within an organization wanting to
prevent access to a specific (user-defined) list of URLs via a low-latency stream-based service.

a. Actual performance may vary depending on network conditions and active services.
b. The number of users is a conservative estimate. When calculating the estimate, we assumed all users
have a high level of simultaneous Internet activity. The actual number of attached workstations connect-
ing via the UTM Firewall could be higher if not all are simultaneously and actively sending traffic.
c. The Enterprise Traffic Mix throughput figures are based on laboratory testing to simulate “real world”
applications and web traffic associated with a small-to-medium sized business (SMB) enterprise. This
test involves a mix of UDP, TCP and HTTP/HTTPS data types.
