The Netrhino UTM Firewall appliance is a network security solution that easily integrates your existing IT infrastructure, providing top notch features to help you focus on your business instead of spending valuable time handling IT security issues.

Launched at Infotech 2006 by TuxLab Ltd, the Netrhino solution won us the Infotech prize for Innovation as being the first Mauritian firewall brand built on open source and targeting SMEs.

Since, the Netrhino has been adopted by several companies in the advertising, hospitality and leisure, consulting, education, manufacturing, construction, public utility, business process outsourcing sectors where it made satisfied customers.

The Netrhino UTM Firewall appliance is a network security tool that easily integrates your existing IT infrastructure, providing top-notch features to help you focus on your business instead of spending valuable time handling IT security issues.
Powered by a FreeBSD as its underlying operating system, the Netrhino provides up to eight fully configurable Gigabit Ethernet interfaces to allow Network Administrators to create multiple LANs, DMZs, WAN links and physical network zones as it suit their needs.

The Netrhino also integrates a transparent proxy and caching engine with a flexible content filter which scans http content for potential viruses and malware. A robust blacklist based filter allows blocking out websites or specific URLs from being accessed by system protected by the Netrhino. To
alleviate the eternal race between new content appearing on the WWW and updating blacklists, the Netrhino also allows adminstrators to filter content based on keywords found in a web page. The Netrhino device can be configured to allow selective access to the WWW with user-authentication either via a locally-administered user account system or by fetching authentication information from an existing LDAP/Active Directory or Radius server in your company.

The Netrhino also offers rich WAN management features such as Load Balancing, Policy Based Routing, Link Failover and that across multiple pools!

To ensure your business continuity, the Netrhino offers a failover solution where a backup device is ready to assume responsibility for taking over, should your primary device fail.
