Our story
Fibersystem is a leader in TEMPEST and RÖS products, Rugged products, secure development and secure supply chains. The history goes more than 40 years back in time working with cyber security and industrial solutions using fiber optical technology.
We are a part of the Swedish Total Defence as main supplier and our products can be found installed all over the world. We provide market leading-edge products mostly to the defence industry but also to other industries, both within IT-security and OT-security. Fibersystem AB (reg. no. 556605-4325) is part of the Addtech Group.
Cyber security products
Engineers, a test lab and a production line sit in the same building in Bromma, Stockholm. That is why an answer to a technical question takes hours rather than weeks — and why a product can go from requirement to certified series production without leaving the company.
It also means the people who designed a product are the people who answer for it. When a customer calls about an interface, a certification level or an installation problem, the call reaches someone who has had that unit on the bench.
Why Fibersystem
Sweden's reference supplier
Main supplier to the Swedish Total Defence and a NATO-certified TEMPEST supplier. Our equipment is installed in command centres, hospitals and power grids – and carries Swedish Armed Forces M-numbers, not just a datasheet claim.
Solutions by sector →From idea to certified end product
Most of this catalogue began as one customer's requirement. Design, development, certification and series production happen in one building in Stockholm – no outsourced engineering, no third-party supply chain. Missing an interface, a protocol or a form factor? That is a project, not a problem.
How we work →Certified, not claimed
TEMPEST Level A & B, RÖS U1/U2, SDIP-27, ISO 9001 and 14001 – certified per product by accredited laboratories. Every claim on this site has a document behind it. Ask for it.
