All three appliances, which are designed to provide the security of a firewall, as well as offering remote users the ability to connect to them or through them to a central office via a VPN, offer 75Mbits per second of firewall throughput and 20Mbits per second of VPN throughput, according to the company.
The devices each sport six 10/100 Fast Ethernet ports for local networking and offer packet filtering, application-level gateways and more, the company said.
Each device also comes with a 90-day subscription to WatchGuard's LiveSecurity software update and security alert service, as well as a one-year subscription to the McAfee Security VirusScan ASaP service.
The Firebox SOHO 6 entry-level model offers all the above features, but does not include any VPN clients for remote users or for connecting to corporate offices. The device costs $469 (£306).
The Firebox SOHO 6tc is the same as the SOHO 6, except that it includes one Mobile User VPN licence and one branch office VPN licence. Mobile User licences allow users to connect to the WatchGuard boxes over a VPN, while branch office licences give the entire office a method of connecting to a remote corporate network. Additional licences are granted with the purchase of WatchGuard's VPN Manager product. The SOHO 6tc costs $629 (£411).
Finally, Firebox SOHO 6tc-50 offers five branch office and five Mobile User VPN licences and is designed for offices with more than 10 users, the company said. The SOHO 6tc-50 costs $899 (£587).
All mobile user VPN clients include a personal firewall, the company said.
