OSINT tools in local government.: So what can be checked?

Opis

Open Source Intelligence. The use of white intelligence in local government is not only a Google browser, but also other tools to check our contractor in activities for the local government, as well as effective promotion and checking the effectiveness of marketing activities on the web.
OSINT is based on what is available on the Internet and what we can get while sitting in front of a computer.
What issues do I raise:
1) Who bought a given Internet domain and when is it valid?
2) How to check if our domain is free?
3) Which domains are better not to enter in Poland?
4) Who got funding from the European Union in Poland?
5) Who received public aid?
