Data Centre Security

Data centre security is a hot topic. Organisations are scrambling to take cyber-steps to ensure that their user data is safe. But what about the data centres themselves?

Physical server racks contain a wealth of sensitive data, but are often an afterthought when it comes to data security. Too often, server racks are left unlocked or completely unmonitored. This makes these server racks vulnerable to costly data theft. RACK ARMOR™ solves that problem by giving you maximum control over your physical racks, including monitoring who opens your cabinet doors, tracking how long they were accessed, and allowing you to remotely lock or unlock a specific cabinet door in an instant, from your desktop.
