While it's mostly only blue/leftist states in the US that require security guards to be licensed, in the EU all countries are required to license security guards. [Link] and excerpt:

If you read on:"In addition, persons in dependent employment may only be entrusted with guard duties if they have completed an 40-hour instruction course."
The muzzie clowns only had to take a 40(!) hour course at the chamber of commerce and they were good to go (actually, they'd probably also have to supply a clean "Führungszeugnis" - meaning no prior felony convictions).
This hardly reaches the level of "state licensed" - like, say, a doctor or attorney would have to be.
PS: This German page doesn’t even list the 40 hour course as necessary for employment as a security guard:
