What We Do

Adder’s range of high-performance keyboard, video and mouse (KVM) solutions enable the real-time control of local, remote and global IT systems. Trusted by some of the world’s leading organizations, from transport hubs like Heathrow Airport to leading post-production houses such as Skywalker Sound and Illumination Entertainment, our products are renowned for their technical excellence and reliable performance.

We enable our customers to extend, switch and remotely manage their computers either locally or via an IP network.

Our High-Performance KVM Solutions

Adder’s high-performance IP KVM solutions improve user experience, desktop ergonomics and production workflows for customers around the world.

Our KVM switch technology is used by control room operators to access and manage multiple computers from a single workstation – often in a fast-paced and mission-critical situation. While our KVM extenders help operators working in extreme and hazardous environments to access their critical computers from a safe and remote location.

Adder’s portfolio of Secure KVM products is used by Government and Military organizations around the world to securely access and manage computers – whether they are housed in a traditional command and control center or on a military submarine.

Our KVM matrix technology combines all this functionality to deliver endless connectivity possibilities. Leading broadcasters, motor sports teams, social media powerhouses and world-leading transport hubs have all identified the benefits that a KVM matrix can deliver – unparalleled flexibility, huge cost savings and improved resiliency.
