Principles of our Technology

We encrypt your programs with a standard crypto algorithm and decrypt them before execution. The secret key or password is calculated on the fly and cannot be extracted using decompilation or other methods. This technology has been developed by BIS Guard & Co. and is its know-how.

Software Development Company of the Year!

We are very excited about the technology you are developing. We spent some time on your web site and we think this can have a very significant effect on the industry. This is not our opinion only. Big boys from IBM think the same.

Our Eclipse plugins: Java Antidecompiler version 9.8 and Java Antidecompiler for API version 3.0 are placed here

Here are our plugins for IntelliJ IDEA IU: Java Antidecompiler version 9.6 and Antidecompiler for Android version 2.4

Great work! For more than a year I'm looking for a good Antidecompiler that encrypts java byte code. All that I've seen is good obfuscators, and one Excelsior Jet Compiler that "encrypts" the java classes. I was very impressed by your work. I am dealing with java applications for few last years but I haven't seen such a pro team like yours.
