About ASUS Control Center Express
Optimize IT endpoint management

ASUS Control Center Express (ACC Express) is a centralized platform designed to assist IT staff in monitoring and controlling devices within their corporate networks, and facilitate inventory checking in multiple locations remotely to help safeguard against potential issues. Its detailed dashboard provides real-time data to identify system failures and efficiently improve productivity, as well as perform timely asset management checking.

Automate IT maintenance

ASUS Control Center Express (ACC Express) allows IT staff to schedule automatic updates of the latest BIOS, software and utilities to specific or all devices at off-peak times, enhancing system stability and IT operational flexibility. ACC Express is designed to enhance power management by setting up power caps to optimize energy usage and reduce outage risks. ACC Express also automatically notifies IT staff in the event of unusual conditions or changes to any device, allowing for faster resolution of potential issues.

Securely manage all of your endpoints

Security is exceptionally vital in any business environment. ASUS Control Center Express (ACC Express) helps IT staff securely manage endpoint configuration, portable storage access and PC software applications by enabling them to create grouping rules on individual devices. ACC Express prevents unauthorized system access by providing remote disablement of the Registry Editor, blocking USB storage for all nodes at once and monitoring client device status, and providing automatic reboots via watchdog programs.
