The list

What being on it
actually means.

Every line below is CNB's own wording, quoted from its site and dated. None of it is ours, and each quotation links back to the page it was read on.

Understanding the CNB warnings

The Czech National Bank publishes dated public warnings when it identifies risks connected with a named offer, provider or website in the Czech financial market.

Directly named websites

Only domains shown in the warning’s own Web field are included, alongside the entity name from that notice.

Original wording

Open the source for the precise activity or authorisation concern described by the CNB. Most notices are in Czech.

Check the registers

The CNB maintains separate official lists of regulated and registered financial-market entities.

A missing warning does not establish that a provider is authorised.

From an official warning to a Snyfer analysis

Use the archive to open the original notice and the domain's Snyfer page. Where scan results and network matches are available, they add technical context. Those matches are Snyfer's analysis; they are not additional findings attributed to CNB.

The numbers

What the archive
shows.

  • Snyfer currently tracks 46 notices published by CNB.
  • Those notices name 55 distinct domains, an average of 1.2 per notice.
  • February 2026 was the busiest month, with 9 notices.
  • Over the last year that is about 3 warnings a month, counting one per domain named.
  • 1.8 percent of the domains CNB has named are grouped under Bullmask Brokers.
  • One group was still being flagged in the three months to Feb 27, 2026.
  • The most recent notice we hold from CNB is dated Sep 10, 2026. We log notices as they are published and do not track removals, so this archive is a record of what was filed, not of what is listed today.

Clusters

Names that travel
together.

Domains CNB has named that share technical traits with one another. A regulator names firms one at a time; the infrastructure they share is ours to see.

Grouped by shared technical traits. That is a lead, not a verdict: shared hosting, common templates and reused libraries also tie together large numbers of unrelated sites. Check each domain on its own report before drawing a conclusion about it.
