USG20-VPN - Next Generation Unified Security Gateway VPN Firewall

USG20-VPN / USG20W-VPN provide safer and reliable VPN connections. Networking brings convenience and efficiency to business environments; however it introduces significant security and safety concerns at the same time. Today; small businesses or branch offices really need a complete yet affordable solution that not only bridges communications between two or more remote sites; but also connects multiple VPNs and ensures data security to prevent the network from threats.

  • Comprehensive supports to IPv6
  • Robust hybrid VPN (IPSec/SSL/ L2TP)
  • High-performance SPI Firewall
  • Bandwidth management
  • High Availability (HA) with multi-WAN failover and loadbalancing

Safer; More Reliable Vpn Connections

Faster processors today have vastly boosted the capabilities of attackers to decrypt VPN tunnels. Legacy VPN encryption algorithms like Message Digest 5 (MD5) and Secure Hash Algorithm 1 (SHA-1) are no longer sufficient to guarantee secure outbound communications. With supports to the more advanced Secure Hash Algorithm 2 (SHA-2); the VPN Firewall provides the safest VPN connections in its class to ensure maximum security for business communications.

Unlimited Business Mobility

To support dynamic; mobile business operations in today's BYOD (bring your own device) business environments; the VPN Firewalls offer unlimited business mobility with Layer-2 Tunneling Protocol (L2TP) VPN for mobile devices. The VPN Firewall supports L2TP VPN on a wide variety of mobile Internet devices running the iOS; Android and Windows mobile platforms.
