As part of our Think Shield security solutions, we offer a combination of hardware and software that work together to keep your system and your data safe. The Think Centre M90a all-in-one boasts smart USB ports to prevent unauthorized people from uploading files, while a chassis intrusion switch detects any attempts to remove the system cover. Trusted Platform Monitor encrypts your data and your passwords. And biometrics let you use your face to log in with the optional hybrid IR camera. The optional Privacy Guard display panel on the M90a features an electronic filter to keep your screen private–and it’s easily controlled with just the touch of a button. When on, if someone glances at your screen from an angle, the panel appears black. What’s more, the display automatically blurs when you look away, which further secures your critical data.
