heavy overkill.....F-Secure is a complete security suite. He has a very good behavior blocker, so just need a webfilter/blocker
like "traffic light" and you are fine.
Cylance is more a wingman for main av with just signature-detection or anti-exe ( combo with Voodooshield or OSArmor)

Personally I wouldn't bother with Cylance if you have F-Secure. Their DeepGuard module is really good and I just don't find any justification for spending money on 2 products that overlap to some extent. Instead I would suggest you to use Syshardener with F-Secure. Syshardener minimises the attack surfaces/vectors and hardens your OS against script viruses that most AV's are weak against.
