Martijn Fokker rejoins our design department
This is a man who loves the impossible. After seven years, we welcome Martijn Fokker back to the Comtest family. “I have been working at Comtest for 16 years and thought it was time for something different, but there’s something about these chamber projects that kept me coming back,” says Martijn.

“Security will enter a new stage in 2026, but we are prepared.” In a series of five posts, our specialists share trends and developments for 2026. This week, Vincent van de Vrie, from our team of Technical Consultants, highlights the growing demand for higher levels of protection.
Vincent van de Vrie: “Governments, financial institutions, defence, and large corporations are increasingly vulnerable to information-leaking attacks, including RF interception and electromagnetic eavesdropping. Our range of TEMPEST shield rooms blocks all compromising emanations and leaks no signal.”
What are the potential weak points of a TEMPEST room?
Vincent: “Data leakage via cables and doors is our focus in our design. Our TEMPEST doors are multi-sealed, and in our rooms we use fibre-optic feedthroughs and special TEMPEST-qualified mains power line filters. Our chambers are EN 50147-1 certified and meet strict governmental or military standards, such as SDIP. We have helped several NATO members over the past 40 years, so we are fully aware of these requirements, including handling highly confidential data within our company.”
Where do you expect a change in demand for 2026?
Vincent van de Vrie: “I see a more practical challenge today: how do we help regular construction companies that will build these secure facilities for their governments and military departments understand the strict TEMPEST requirements for our rooms in their new buildings? To them, I would say, contact me for advice to avoid any non-compliance and unforeseen security breaches.”
Governments, financial institutions, defence and construction companies that want to prevent any information-leaking attack can contact Vincent van de Vrie for a Comtest Engineering-accredited solution.
