W&T Microwall VPN (Firewall) with WireGuard VPN Server

Click2Contact

Software components of machines, PLCs etc are targets for attackers on the internet. Small compact firewalls can be used to isolate the machines or PLCs by segmenting traffic and thus increasing security in the control or corporate network.

The W&T Microwall VPN separates sensitive components or subnets into a separate island network and keeps them from being accessed via the higher level company intranet. For remote access, for maintenance and remote support, a WireGuard VPN server is available to provide selected VPN clients with secure and dedicated firewall-protected access to the island stations.

All connections between the networks must be given explicit permission via rules, based on source/destination IP and the TCP/UDP port numbers. Communication with undocumented or undesired services is prohibited and harmful events, such as overload, are kept from the island.

The firewall rules and VPN management are administered simply and clearly using the Microwall VPN web pages and are uniformly whitelist-based. Any communication that is not expressly permitted in the form of a rule is blocked.
