Summary

Switzerland recorded an increase in official surveillance measures of approximately 40 percent in 2025 compared to the previous year. The Postal and Telecommunications Traffic Surveillance Service (ÜPF) documents this development in current statistics. The driving force is primarily cell site searches, which increased by 69 percent (19,091 cells in 2025 vs. 11,290 in the previous year). The measures are carried out on the orders of law enforcement authorities or the Federal Intelligence Service (NDB). In parallel, the number of disclosures to law enforcement authorities increased by 32 percent, including complex disclosures by 39 percent.

The escalation of surveillance activity falls in a year of heightened security policy activity. With an increase of 40 percent, Switzerland signals a significantly intensified digital investigation practice – parallel to similar trends in Germany, where facial recognition searches at the BKA have doubled. Particularly noteworthy is the disproportionate increase in cell site searches (69%), which comprehensively collect mobile phone data, while specialized technologies such as GovWare (government trojans) are sharply declining. For data protection debates and legislation, this creates tension: mass data collection is replacing selective high-tech methods.

Detailed Summary

The core statistical figures show a differentiated picture. While real-time surveillance increased by only 3 percent (1,878 cases) and searches more than halved, retroactive cell site searches exploded. A cell site search captures all network accesses and communication attempts that occurred within a selected time period via a specific mobile phone cell – a technique that potentially captures large sections of the population.

For disclosures, simple and complex requests differ significantly. Simple disclosures (phone book, IP address queries) were requested 480,245 times and issued 650,034 times (2024: 385,630 requests, 495,119 disclosures). Complex disclosures such as ID copies or contract data increased to 44,836 cases – an increase of 39 percent. The Federal Intelligence Service ordered 334 surveillance operations and made 39,130 information requests (49,393 disclosures issued) – compared to 106 and 12,789 in the previous year, a quadrupling.

In the offense structure, property crimes dominate with almost 45 percent of all surveillance operations (increase of 45%). Sexual offenses show the highest relative increase with over 124 percent, although they account for only 2 percent of the total volume. Offenses against persons accounted for 24 percent (+75%), narcotics offenses 8 percent (+10%). In contrast, specialized technology use declined sharply: GovWare deployments fell from 12 to 4 cases; IMSI-catchers were used 151 times (2024: 171), primarily in emergency searches for missing persons (62 cases) and serious drug offenses (45 cases).

Key Messages

  • Surveillance measures in Switzerland increased by 40 percent in 2025, driven by cell site searches (+69%).
  • Disclosures to law enforcement authorities increased by 32 percent; complex disclosures by 39 percent.
  • Property crimes are the focus with 45 percent; sexual offenses show the highest relative increase (+124%).
  • Specialized surveillance technology (GovWare, IMSI-catchers) is declining; mass data collection dominates.

Critical Questions

  1. Evidence & Source Quality: Is the 69-percent increase in cell site searches based on methodological changes (e.g., different recording criteria) or actually increased operational frequency? What data completeness does the ÜPF report guarantee?

  2. Conflicts of Interest & Incentives: Do law enforcement authorities benefit from lower legal barriers for cell site searches compared to targeted surveillance? What controls prevent misuse of mass data queries?

  3. Causality & Alternatives: Does the increase in cell site searches actually lead to higher investigation success rates, or is it a cheaper alternative to selective methods? Which alternative investigation approaches were evaluated?

  4. Implementation & Risks: How are data protection and proportionality principles verified across 19,091 cell site searches per year? What deadlines apply for data deletion for captured individuals who were ultimately not charged?

  5. Side Effects: What impact does mass data collection have on companies (cell site operators) and private users regarding data processing and storage burdens?
