Overview of Olfeo protocol filtering

Protocol filtering functions

The Olfeo protocol filtering solution allows you to control Internet protocols at the application level (Layer 7 of the OSI model) in order to ensure content filtering quality and optimal security.

Olfeo protocol filtering provides comprehensive blocking, including dynamic protocols, by analyzing application signatures including UDP and TCP.  It detects and controls more than 850 protocols divided into 28 themes based on protocol fingerprints or certificates for encrypted connections.  An excellent knowledge of the structure of exchanged data allows protocol identification regardless of the port used.

The rules engine for protocol filtering has a very fine level of granularity useful for policy setting.

Protocol filtering policies can be individually assigned to groups or to users in the same GUI as the URL filtering so as to have a global view of filtering policies.

Protocol filtering provides an additional layer of security to URL filtering and the Olfeo antivirus, thus ensuring optimal content filtering.
