English to Spanish Tech/Engineering IT (Information Technology) Networks

I understand the meaning of every single word, but what puzzles me is the use of "to". Does it mean "from...to..."?

This is the title of a section of the overall document on networking. The text that follows is this:

"AAA addresses not only the day-to-day management of security devices at Layer 3 through 7 with our local expertise across products and platforms, but also monitors your business risks found within the actual content across all of your TCP communications and most applications leaving your corporate networks."

Many thanks in advance
