There are two ways a legacy technology solution gets retired. Gradually, and all of sudden. No one likes outdated file servers. Employees dislike their clunky, unfriendly user experiences compared to more modern, cloud-first tools.

And when your workers are driven to unapproved — and insecure — consumer file services, your risk of data breaches and penalties from regulatory non-compliance essentially doubles.
