mGuard security appliances for the DIN rail

FL MGUARD RS2000:  the security routers offer a simple “2-​​click​” firewall and up to two parallel, IPsec encrypted VPN tunnels. Its scope of functions is kept to the essentials and is primarily suited to secure remote maintenance in industrial applications 

FL MGUARD RS4000:  thanks to the intelligent firewall and up to 250 ​​IPsec​​-encrypted VPN tunnels, the ​security appliances​ offer an extended range of functions. They enable high-end security for demanding high-availability scenarios and complex security architectures.

​FL MGUARD GT/GT:  the security routers feature similar functions to the devices from the RS4000 series. What is more, they are also gigabit-compatible. In addition to RJ45 ports, they also offer SFP ports for flexible use of single mode and multimode fiberglass cables.

PCI and PCIe cards

mGuard security appliances in PCI and PCIe format

The mGuard PCI and PCI Express cards feature the same security functionalities as mGuard DIN rail devices in a compact, PCI-compatible plug-in card. You can therefore equip any PCI and PCI Express-compatible hardware with a powerful security component.

The PCI cards are ideally suited to distributed protection and remote maintenance of industrial and panel PCs, individual machines or industrial robots. They operate independent of the processor technology and operating system.

Portable hardware

mGuard security routers for mobile applications  

Portable mGuard security appliances

The mGuard smart2 features security and performance in confined spaces. The housing is robust and the power supply can be easily established via any USB port.

It is particularly suitable for the mobile protection of workstations and environments close to the production process with low requirements for industrial hardening. Perfectly positioned as an intelligent firewall between office and production networks, as a secure and software-independent remote maintenance solution or as a security router for small workgroups.

mGuard Secure VPN Client

The mGuard Secure VPN Client is a software application for connecting Windows PCs to a virtual private network (VPN). In doing so, the client provides resources from remote networks via a public, potentially unsecure network, for example, the Internet, in a highly secure and transparent manner.

The software solution uses the IPsec security protocol. This guarantees the confidentiality, authenticity, and integrity of all information and data transmitted between the VPN client and the mGuard. Ideal for service engineers and teleworkers, the VPN client supports both mobile and stationary application scenarios. It is compatible with the entire mGuard product range and is extremely easy to operate as a “one click solution”.

Desktop device

mGuard security appliances for desktop use

The mGuard delta combines a high level of security and performance in a compact metal housing as a desktop device. It can be used as a secure firewall between office and production networks. It is also suitable for use as a security router for small to medium-sized workgroups in desktop applications, in distribution compartments, and other environments close to production processes with low requirements for industrial hardening.

In medium-scale machine building and systems manufacturing, in particular, the mGuard delta acts as a reliable teleservice infrastructure. MGuard delta allows you to connect machines, controllers or engineers in a secure way.

19'' security appliance

mGuard security appliance in 19" format

The mGuard centerport is a combination of a high-end firewall and high-performance VPN gateway in 19" format. The device offers Gigabit Ethernet and multi-core architecture as well as high power reserves. This means the mGuard centerport can be effortlessly scaled with a continually increasing number of VPN connections or network segments to be protected. A consistent transmission rate is ensured for business-critical IP services even at maximum load.

As a central high-performance gateway, the mGuard centerport supports the VPN connection of any number of systems, machines, and engineers. Up to 3000 VPN tunnels can be simultaneously active.
