Who Needs Transparent Screen Lock security software
for Windows XP/2003/Vista/2016/7/8/2016/10/2019

Anyone who needs to Password Protect access to their workstation or server. TSL provides a secure password mechanism - and runs "transparently", so you can still monitor the programs that are running. This is ideal for:

  • System Administrators: control access to single-user or multi-user systems in a corporate environment. TSL-SMART CARD provides additional security, with support for Windows-based SMART CARDS to control computer access.

  • Labs and Production Floors: monitor processes while maintaining access control: 'see, but do not touch'.

  • Retail Stores, Kiosks, Tradeshow Demos: prevent unauthorized access.

  • Home users: parents can control a child's computer time; email or instant message users can monitor incoming messages, while restricting access to your computer.

  • Transparent Screen Lock enables IT professionals to prevent unauthorized system access, while maintaining the ability to view applications running on the desktop for monitoring purposes.

    Transparent Screen Lock delivers system security measures that are essential in today's open-concept corporate offices with free movement of employees and visitors, as well as in high security environments such as financial institutions and banks, hospitals and pharmaceutical research facilities, government offices and military installations.

    With its ability to limit system access to authorized individuals in both stand-alone and multiple-user shared computer environments, Transparent Screen Lock is ideal for facilities which must ensure compliance to the 21 CFR Part 11 code of federal regulations.

    With new optional support for a hardware proximity sensor, TSL delivers maximum security by automatically locking the system when the user steps away from the station. When the user approaches the system, TSL's password-protected logon screen is automatically displayed.
