Here is the answer from Viro, the lock manufacturer.
Monolith
Cylinder: 7 pins, replaceable and re-keyable
Key: Top Security profile
Certified https://www.viro.it/files/certificazi...
Euromonolith
Cylinder: 6 pins, replaceable
Key: flat, reversible
Not certified
The main difference is the higher number of combinations of the 7-pin Monolith. However, the reversible flat key of the Euromonolith is less common in the USA and therefore less likely to be copied.
