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.

Annual report 2019 PTSS

The Post and Telecommunications Surveillance Service PTSS is publishing an annual report for the second consecutive year.
The report reviews the past year, provides an insight into how it works collaboratively with telecommunications providers and law enforcement services, and documents its activities in facts and figures.

The report 2019 is available for download in English, French, German and Italian.


Statistics 2019

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 has steadily increased in 2019.

According to the figures and a comparison with the total number of offences committed (2019: 544,781), telecommunications surveillance is used in about 1.5% of all offences.





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.
