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 Swiss prosecution authorities and the Federal intelligence service (FIS) may order post and telecommunications surveillance measures for the purpose of investigating serious criminal offences.
The overall number of surveillance measures ordered remained stable in 2020.
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.
