Implementing either face or fingerprint scans that would unlock a database of all employees and their surveillance level to ensure that the person is cleared to access whatever data they need. With face scans it almost makes it impossible that you will have unauthorized access and system breaches. The scans would process who the person is and if they have the clearance for the system. While they have access there will be screen recordings built in that montiors every thing that is done on the system regardless of browser, and will shut down and raise an alert when malicious activity is detected. This way company data and systems are sound tight and protected, and if there was a breach the person responsible will be quickly found.
