Businesses run on other people's services, and those services arrive on the vendor's paper. The terms are presented as standard, they are rarely negotiated, and they are usually read once at signature, if at all.
The provisions that matter are predictable. What happens to your data — whether it is retained, where it is processed, whether it is used to improve the vendor's product, and what you get back when the relationship ends. What the vendor actually promises about availability and performance, as distinct from what its marketing implies. Who bears the risk if the vendor infringes someone else's rights, and what its liability is capped at, which is frequently a fraction of what a failure would cost you.
Then the terms that reach past the vendor itself: what obligations flow down to its subcontractors, and whether a commitment made to you binds the people actually doing the work.
The Firm reviews and negotiates these agreements from the customer side, and drafts them for businesses that supply services to others. The analysis is the same in both directions; what changes is which side of each provision you want.
Standard forms are standard because they were drafted for the vendor. Which terms are worth pressing depends on what the service actually does for you.
