I'm renewing our old outdoor concrete staircase going to the garden. I've decided to install glass mosaic as surface finishing. I've got advice from the specialized shop regarding water-proofness of the seams and appropriate bedding.
Now I'm wondering whether I should install a protective 'nose' profile on each step (embedded in the thinset at placing time).
Would the mosaic be resistant enough on it's own or should I consider some alu profile?
As illustration, here's a mosaic sheet resting on a step.

Absolutely. Those tiny tiles will chip or pop off as soon as somebody smacks it with something. I assume you are thinking of some nosing like this and where I live, I would certainly go with something with some grip.
Not knowing what kind of traffic the stairs get and what your climate is like (how often it freezes - how often they are wet), it's hard to make a more informed recommendation, but those thin small tiles will not take much abuse.
