What is a Box folder?

Excuse me, could you please elaborate on what a Box folder is? I'm not entirely familiar with the term, and I'm curious to know more about its purpose and functionality within the realm of digital storage and collaboration. Is it a specific type of folder used within a cloud-based platform? And if so, what are its key features and benefits compared to other similar services? Additionally, are there any security measures in place to ensure the safety and privacy of the files stored within a Box folder? Thank you for your time and consideration.
