Do It Yourself security

for machines and plant

Firewall directly on the machine

W&T firewalls secure machines, plant and other devices that need protection quickly and easily. These industrial grade firewall routers can be DIN rail installed and located in the network architecture directly before the network device to be protected. The result is a secure network island. This type of network segmentation is accomplished according to individually configurable communication rules: communication with selected network devices, users or services can be allowed, while all other undesired communication attempts will be thwarted.

Hit the nails on the heads!

With the WuTility and configuration through the web interface, no great IT expertise is needed. Integration requires no cumbersome rearrangement of the network architecture.
