Has e-Privacy come into effect?

In "Module 13: Sustaining and improving compliance", in the "Keep Looking Forward" video, the lecturer says that the e-Privacy regulation is in the drafting stage and will soon set rules for privacy and security in the context of electronic communications. My question is, has the e-Privacy already come into effect?

I assume that you are referring to Advisera's EU GDPR DPO Course, Module 13. E-Privacy regulation is still a proposal to be approved by the European Parliament. The approval procedure is not concluded.

And where can I find out more information about it?

You can find all information about e-Privacy regulation discussion on the Official European Union websites.
