New Hackshield?

I did a quick google search and thought I would post a list of different features that the 2 Metioned anti-hack programs offer

Major Features in PunkBuster™
(some editions of PunkBuster™ do not have all of these features)

Real-time scanning of memory by PB Client on players' computers searching for known hacks/cheats
Throttled two-tiered background auto-update system using multiple Internet Master Servers to provide end-user security ensuring that no false or corrupted updates can be installed on players' computers
Frequent status reports (highly encrypted) are sent to the PB Server by all players and the PB Server raises a violation when necessary which causes the offending player to be removed from the game and all other players are *******d of the violation
PB Admins can also manually remove players from the game for a specified number of minutes or permanently ban if desired
PB Servers can optionally be configured to randomly check player settings looking for known exploits of the game engine
PB Admins can request actual screenshot samples from specific players and/or can configure the PB Server to randomly grab screenshot samples from players during gameplay
An optional "bad name" facility is provided so that PB Admins can prevent players from using offensive player names containing unwanted profanity or racial slurs
Search functions are provided for PB Admins who wish to search player's keybindings and scripts for anything that may be known to exploit the game
The PunkBuster™ Player Power facility can be configured to allow players to self-administer game servers when the Server Administrator is not present entirely without the need for passwords
PB Servers have an optional built-in mini http web server interface that allows the game server to be remotely administered via a web browser from anywhere over the Internet
