Efficient Software has a minimal install footprint, uses little server RAM, and has no framework or library dependencies. It exceeds my expectations. The software is the most stable I've ever seen. I found an extra module for Windows that's anti-hacking, plus I get regular updates. It just keeps running without any problems. Review collected by and hosted on G2.com.

I am not aware of just about any significant limitations. I would probably like a more comprehensive manual outlining the principles of software protection and how they are put into practice. The manual provides detailed descriptions of each function, but the examples are the only ones that make the implementation process clear (easily readable for developers). Simply put, I was juggling support with the implementation process, which was compounded by my FORTRAN compiler. Review collected by and hosted on G2.com.
