For more advanced network and security requirements than the shared firewall service, Silicon Sky recommends our Virtual Firewall Appliance service based on Next Generation Firewall technology. The appliance is deployed within your Virtual Data Center. The Virtual Firewall Appliance service is ideal for requirements such as dedicated internet access, multiple DMZ’s, greater than 5 IP-SEC tunnels and greater than 20 VPN clients. This service is available as a managed service or self service.
