I would recommend staying away from this "shield".
The only server change is a custom login packet that includes your hardware id + mac + a static key. There is no packet encryption or server-side logging.
They are distributing a pirated copy of exe/dll packing software (Molebox) https://github.com/AsiaGenius/ring-0/tree/master/Tools/MoleBox (portable)/INSTALL LICENSE
The client dll connects to their web server to verify everything, if their web server is down; you won't be able to use your client.
Their website / report server is vulnerable to SQL injection, there is 0 input validation.
... etc
If they can't do basic input validation on their web server, I really doubt they're capable of doing advanced cheat detection, or delivering many of the features they claim to support.
Here is a snippet from the report server (http://guard.ringsec.net/) after passing a bit of invalid data. You could compromise all of their accounts / data / etc, and based on the register form showing the password in plaintext; I highly doubt they actually hash your account passwords.
Please stay far away from this software until they resolve all of these issues. Do not use it in production.
