Secure networks for small enterprises
Video ⋮ November 2020
Every fourth small enterprise has no form of cyberprotection. The root problem is the lack of security at the network level. Our value proposition in 45 seconds.
Devices to harden networks from the inside
With network components turning into security systems themselves, no additional devices need to be installed or configured, and attacks within the local network can easier be prevented. Based on proven encryption technology and VPN protocols, plug-and-protect gateways and network-attached storage servers combine security and ease-of-use like nothing else.
