Our S-LOK Security Dongle is a special version of the KEYLOK Dongle that is capable of “wrapping” a protective shell around a program executable without having to make source code modifications. It is a simple, effective means of providing limited security and protection if you are trying to secure your applications from piracy.

S-LOK Dongles provide wrapper–based protection in those instances when source code cannot be modified, or when a simpler method of security will suffice. This method can also be ideal for license management and control of third–party software such as Microsoft Office or QuickBooks, or certain remote access software that you want to protect to prevent unauthorized use or sharing of applications you have licensed.

This wrapper is also often used to provide an additional layer of security to applications that already utilize the more secure application level, API security system calls. S-LOK then provides a final outer level of access to the application.

S-LOK can also be used as an immediate, short–term solution. S-LOK can:

• Protect Your Application In Seconds
• Protect Your Application With No Code Changes Required
• Add An Additional Layer Of Security To An API-Protected Application

The S – LOK Wrapper™ is only available in Parallel.

KEYLOK Networking Dongles come in USB or parallel. You may attach the Networking Dongle to any PC in the network and control the number of concurrent users allowed (from 1 to unlimited).
