Hardware from Parallax
Equipment against eavesdropping and unauthorised access
The IMSI catcher detector watches the mobile network in your offices, in production and on the road. Glaux tells travelling staff whether someone has been in their hotel room. Both are supplied by Parallax ApS, the company that develops NOCTUA.
IMSI catcher detector

An IMSI catcher poses as a mobile base station. Nearby phones connect to it, and their owners don't notice. Whoever runs it can see exactly which phones are present and follow them from place to place. Many IMSI catchers also force phones down to 2G, where calls and text messages can be intercepted.
The equipment is used by state actors and criminals, and it's set up where sensitive conversations happen: at negotiations, at conferences and in hotels where travelling staff stay.
The detector watches the mobile cells that phones around it can see, and alerts on cells behaving like a fake base station. It can be placed in your own offices and production facilities, in negotiation rooms, at conferences, in hotel lobbies and in offices abroad. In short, the places where someone could have an interest in listening in.
Glaux

Glaux is a small version of Sentinel for people who travel a lot and stay in hotels. It watches the room while you're out and tells you whether someone has been in who shouldn't have been.
Glaux registers sound, motion and vibration and gives a simple indication when something has happened. It works fully offline. It transmits nothing, so there's no signal to pick up.

If you want to collect observations from trips over time, they can be recorded as findings in a NOCTUA case.
