Case Study: Grant Thornton achieves hands-free mobile access and improved office experience with Kastle Systems' KastlePresence

Grant Thornton Deploys KastlePresence Improves Office Experience and Enjoys Unexpected Benefits

Grant Thornton, a leading U.S. professional‑services firm with more than 570 partners and over 8,500 personnel across 60 offices, needed a more convenient and secure way for local and traveling staff to access its busy Chicago headquarters. Plastic RFID badges were frequently forgotten or lost, created administrative headaches for after‑hours access and visitor management, and even left scuff marks on entrances when people tried to go “hands‑free.”

Kastle Systems deployed KastlePresence, a hands‑free BYOD credentialing solution that uses smartphone Bluetooth instead of plastic badges. Grant Thornton gained truly hands‑free entry, the ability for administrators to grant remote access from anywhere, cleaner entrances with fewer scuff marks, and measurable operational improvements—leading the firm to consider wider rollout and use of KastlePresence’s workspace‑utilization features.
