Welcome to the homepage of PTSS, the Post and Telecommunications Surveillance Service. This website is aimed at Communication Service Providers (CSP), Law Enforcement Agencies (LEA) as well as the Federal Intelligence Service (FIS) for information, communication and exchange purposes.
The PTSS is responsible for ensuring the implementation of post and telecommunications surveillance measures. It acts independently and autonomously, and is not subject to directives.
The PTSS carries out surveillance measures on behalf of the federal and cantonal prosecution authorities to investigate serious criminal offences. In 2022, the number of surveillance measures ordered has increased by 27 percent. This increase is mainly due to the strong rise in antenna searches.
Persons required to cooperate can submit an application via the extranet in order to have their obligation status assessed by PTSS, for example to have their status changed to CSP with reduced surveillance obligations (Downgrade). Documentation supporting the application must also be submitted here. Furthermore, the persons required to cooperate can communicate changes to their details, for example the contact details of their LI-Officers, via the extranet.
