HradBa 2 
The term HradBa is Czezch and means "Castle Wall". The HradBa Anti-Cheat System was developed by PTERODON, the developers of Vietcong, in association with United Admins Limited to restrain multiplayer cheating in the Vietcong series. Even though development of HradBa and HradBa2 has ceased, the latest versions can still be used. More HradBa details - here -
