Just think of it as a force field of sorts, except instead of guarding yourself physical attacks from an enemy or potential threat, you’re protecting the Radio Frequency (RF) signals that much of your electronics create from reaching the outside world.

That’s the basic premise behind a Faraday cage, which is traditionally defined as a special cell-like area or room that is surrounded by or protected with signal-blocking material. English scientist Michael Faraday first proposed this concept in the mid-1800’s, and even today Faraday cages are utilized for a few select purposes. One, they can house electronic equipment in an effort to prevent signals from interfering with the signals of other nearby electronic equipment. Or, as is the case with traditional office environments, they can be used to prevent RF signals emanating from the likes of computers, audio recorders, Internet routers, phones and more from exiting a particular facility. When RF signals exit a facility, they may be prone to hacking and data theft from outside threats, hence the value in a Faraday shield or some version of this.

In addition to preventing RF signals from exiting the environment, Faraday cages also prevent external signals from entering.

A Modern Day Faraday Cage

We get how it might seem a little odd to have a small “cage” in your office where all of your electronic equipment is stored. Today, many commercial and government firms, data centers, and urban offices take the Faraday cage concept to their own customized level, to meet their specific needs.  They may use the likes of RF-blocking window films, foils, fabrics, paints and more to prevent these signals from reaching beyond a facility where any hacker could be waiting to intercept them, or just to reduce external interference from neighboring facilities and equipment. By taking the appropriate measures to safeguard an entire office, you reduce potential threats, increase your technical security posture, and improve your technological efficiency and capabilities with your space.

How to Create a Total Office Faraday Cage

Looking to improve your office security and implement a version of a Faraday cage to your building?  Signals Defense offers many of the technologies to allow your business to do it. Here’s a look at some of the technologies to help prevent RF and IR signal theft:

  • RF window films: These install easily and are barely noticeable following installation. What’s more is they prevent signal release through one of the most vulnerable areas of a building — the windows.
  • Special foils, fabrics and paints: These install easily on the outside facing walls of a building to provide an extra layer of protection.


Is the threat of an external hacking from electronic espionage a concern for your company? Is it even on your radar? If you have confidential or important data that could cripple your business if it fell into the wrong hands, then it should be a priority to protect it.
