Post and Telecommunications Surveillance Service

Post and telecommunications, of which the Internet is a part, contain information that may help solve serious crime. The Surveillance Service monitors post and telecommunications by order of law enforcement agencies. It is important to note, however, that all surveillance is subject to prior approval by a judicial authority, a cantonal or federal coercive measures authority. Surveillance consists in gathering from telecommunications providers data as requested by the authorities and required for solving crime. Telecommunications providers are bound by the instructions of the Surveillance Service.

The Surveillance Service also advises telecommunication providers and law enforcement authorities on technical and legal matters.

In addition, the Service executes legal assistance requests by foreign law enforcement authorities seeking to have post and telecommunications surveilled in Switzerland.

The Surveillance Service cooperates with various national and international telecommunications licensing and supervisory authorities. This allows the Service to remain up to date on the latest in technical developments and to have a say in shaping the standards set by the European Telecommunications Standards Institute (ETSI).
