Facts and Figures
Founded in 2004, Praetorians is still a young but ambitious company in the IT business. Both founders, the brothers Andreas and Wolfgang Zelezny, concentrate their expertise on a steadily growing segment: data and information security. The mission is to produce reliable and comprehensive protection of information.
The first product of Praetorians, the security software solution "Secure Calc", ensures that sensitive data in Excel applications are secured by a professional, customizable, but at the same time easy to use encryption method. That way, financial and image losses can be avoided. Secure Calc is the worldwide leading security solution for Excel.
The mission is symbolized by the company's name "Praetorians": The guards of the Roman emperors were called Praetorians. A profession that required trust and reliability. And that is also what Praetorians aims to be: your trustful and reliable partner in all areas of information security.
Our products are characterized by the following features and concepts:
- Simplicity instead of complexity
- Simple handling (simple installation, no administration and user training required)
