I have this combination on a computer at home, does having Hitman Pro Alert, cover what Hard Configurator will do, instead of?
It will not. The main difference is that HMPA does not block/restrict scripting and does not block access to CmdLine.
H_C is much more preventive and tries to block from the beginning anything that is not necessary. So in most cases, the malicious processes are not executed at all.
Most of the HMPA protection is focused on mitigating the already executed processes.
HMPA has got a real-time module to detect the prevalent malware and an advanced anti-exploit module. So, it works similarly to Defender (with some ConfigureDefender settings) + Exploit Protection + Web Browser hardening. The anti-exploit module is easier to use compared to Windows built-in Exploit Protection. The anti-ransomware module of HMPA is more advanced. HMPA covers also several methods of keylogging (not covered by Windows built-in features).
