In the macOS hardening video, the firewall application LuLu by Objective-See was recommended, however to my knowledge there has been no mention of the other FOSS security applications from Objective-See. Some of these applications seem quite useful for further macOS hardening, such as a general keylogger detector (ReiKey), persistent malware detector (BlockBlock), and an application that detects whenever the mic and camera are used and names the culprit (OverSight), among others.
These all seem like nice additions, especially for those like myself who do not use an antivirus for privacy reasons and would like a bit more protection. Is there any reason why these aren’t recommended? I see no reason not to use these applications if LuLu is already being used, as you get increased security without the detriment of having to place trust in a new party. For these reasons, I’d like to suggest maybe adding something about these applications to the description / pinned comment in the macOS hardening video, assuming the applications actually provide worthwhile security improvements.
