Cloud Firewall - Moving security in to the core of the network

Cloud Firewall from Stream Networks enables you to plug your Fibre Ethernet Leased Line directly into your Local Area Network (LAN) and manage your security and IP addressing directly from the Cloud using our State of the Art management portal.

Easily add in additional sites to create a futureproof private network and manage this network without any of the complexity of the past.

Using this service from Stream Networks allows you to say goodbye to your router and say hello to next-generation Ethernet. Whether you are managing 1 site, 100 sites or 1,000 sites, this is the solution for you.

Stream Networks can deliver our range of Cloud Firewalls using open source technology PFSENSE and OPNSENSE as well as Virtual machine images from leading vendors such at Fortinet, Palo Alto and Sonicwall.

As can be seen in the diagram below, each site has its own individual firewall, with the Fibre Ethernet Leased Line connecting directly to the Local Area Network without the need for any more equipment.
