Context

www.rivm.nl is the website of the Dutch National Institute for Public Health and the Environment (RIVM): vaccination, infectious-disease control, environmental and sanitary safety, and health research. The data controller is RIVM, a government organization. The site is informational.

Scan: 29 requests to 8 domains, homepage, captured in a clean Edge browser without a VPN or ad blocker. The technical stack is restrained.

Who receives the data

There are no third-party commercial recipients.

There are only two external services: the government’s centralized web-statistics platform, built on Piwik PRO in anonymized mode, and a functional survey tool for collecting feedback. The scan shows no Google Analytics, no advertising networks, no social media pixels, and no session recording.

A full banner for the statistics is not required here: it is configured anonymously — it anonymizes the IP address and does not intrude on privacy, and is therefore exempt from consent. Not a single cookie was set during the entire session. The survey tool operates on user request.

Only anonymized government statistics and a functional survey tool. Before any interaction, the government’s centralized, anonymized statistics and preparation of the survey tool fire. The scan contains no Google analytics, no advertising domains, no social plugins, and no session recording.

Conclusion

Rivm.nl is a model of a restrained configuration for a public-health institute handling particularly sensitive subject matter. There are only two external services: the government’s anonymized web statistics and a functional survey tool. There is no third-party advertising, no Google analytics, no social media pixels, and no session recording whatsoever, the statistics tool anonymizes IP, and no cookies are set. The key takeaway for the reader: a public-health institute can manage with its own anonymized statistics alone, and here that is achieved without a single third-party commercial tracker. No violations were recorded.
