Is DossierData BV safe?

Low risk

DossierData BV lets iwize.nl pages drive scraping of Dutch government portals and can forward DigiD login values.

The extension runs on Dutch government sites (tax, pension, UWV, DUO, DigiD) and carries out actions requested by iwize.nl or localhost pages, such as opening tabs, clearing cookies, clicking, filling fields and downloading PDFs or HTML. When the requestor turns on sticky credentials, it captures the DigiD login values on button click, encrypts them with a key built into the extension and passes them back to the requesting page. The external message handler does not check the sender.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 3 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed DossierData BV contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
