Searching for a song

Excuse the disturb, someone that know this song is so kind to tell me the name?
I would like to buy it.
And also, i’m searching an author but i see only the search bar for songs, how i can search it? Him name starts with “cinematic” and him icon brand is an azure square (months ago, idk if now have the same yet).
The song : 1.25 MB file on MEGA

Thank you!
