I like all three of these. I would like to see them in different colors if you don't mind. Maybe some silvers, blacks or anything else you think would look good.
I like the lettering in 15 and 18. The color may be too light for us. While I like the abstract ball in 15, it's probably not right for our industry. Tech is good, but we need security as well. The block in 18 is not the right symbol, either. Still very fond of 28, 29 and 16. 31 and 32 are probably going to be too superhero for us.
#53 Shield for representing the security. The globe inside the shield, representing reach of the world. Shield with lettring MSC representing that MSC company protecting and securing the world.
