Onyx, Swiss intelligence gathering system
Onyx is a surveillance system operated by Switzerland that has monitored international satellite communications since 2000, intercepting phone calls, faxes, and internet traffic. The system filters intercepted messages using keyword searches and is overseen by independent authorities to ensure compliance with privacy laws.
The system was established in 2000 to intercept satellite transmissions and identify security threats. Its operations are carried out through a network of stations located in Leuk, Zimmerwald, and Heimenschwand across Switzerland.
The stations are not open to visitors and are located at protected or private sites. Information about the exact operations and intercepted data is not publicly available for security reasons.
A remarkable revelation occurred in 2006 when a Swiss newspaper published intelligence information intercepted by the system, exposing a secret Egyptian diplomatic report about hidden CIA detention facilities in Eastern Europe. The journalists were later cleared after proving their source came from lawful interception activities.
