City of London School (CLS) is a prestigious independent day school for boys located in London. Their challenges are they need to enable staff and students to securely use personal and school-owned mobile devices, provide guests and contractors with easy, secure access to a guest network and block unauthorized users who attempt to log in. They chose Bradford Networks to overcome these challenges. They deployed to network sentry, Network Access Control (NAC) software from Bradford Networks and Xirrus wireless network infrastructure. The results of implementing the Bradford Networks were achieved greater student satisfaction through easy access to wireless network via mobile devices, simplified guest registration, offloading this time-consuming task from IT and network security for CLS and peace of mind for IT staff.
