A QNAP NAS comes standard with a VPN server built-in. Meaning that multiple employees can connect from on the road and have access to files and services as if they were in the office. Need to print out a document on the secretary's printer, no problem! Read a PDF stored on the shared drive, no problem! Access remote desktop on a computer in the office, simple.
A QNAP NAS supports Mac, Windows, and Linux PC, iOS (iPhone, iPod, iPad) and Android devices equally. You are never locked away from your data. Native mobile apps actually let you manage and work with your NAS and data while on the go.
