The USG Pro is a beefed-up version that offers more powerful internal hardware designed for enterprise users, like businesses that have many cameras and users. The company calls it an "enterprise gateway router with gigabit ethernet" capabilities. It has a 1 Ghz dual-core processor compared to the USG's 500 Mhz dual-core chip, and 2 GB of DDR3 ram compared to the USG's 512 MB or DDR2 ram, which both improve its speed over larger deployments.
