Secure remote maintenance with WireGuard

The Microwall VPN enables protected remote access

Network specialist W&T introduces the Microwall VPN, as user-friendly solution for remote maintenance of devices and equipment.

The micro-firewall with integrated Wireguard VPN server enables encrypted remote access to systems installed at your customers’ location without the need for access to the surrounding network by external service providers. Also eliminated is the need to reroute data traffic through a meet-in-the-middle server.

A UDP data stream is used to construct an encrypted tunner between the network segment guarded by the Microwall and a Wireguard client. Such clients are available for all large mobile and desktop operating systems. Authentication is accomplished using key pairs which are generated over the web interface. All successive configuration is also done over this interface. At startup one simply configures the router and firewalls in the network so that incoming UDP data traffic for an individual port is passed along to the Microwall VPN.

In its own network the Microwall VPN protects vulnerable systems from attackers and malware. Older systems with needed services having known security gaps are thus insulated within their own network. Access from the outside is only through cryptographically authenticated clients. There is however no restriction to the functional scope: by setting up firewall rules you can allow the affected system access to the required services in the surrounding network.

The Microwall VPN is available from Wiesemann & Theis for 498.00 €. Commercial customers can test the product for four weeks at no charge by ordering article number 55211. For additional information go to www.wut.de/55211.
