We have over literally over 20 Apple devices in our home (and on our network) and I am considering working part-time contract work online. I need to know what Apple recommends as the best cybersecurity for your devices? I do not want background apps being loaded without my permission, other malware / spyware or any other things that would compromise our systems &/or devices or information. Is there something that would be best for the MacBook Pros or something that could protect the network as a whole?
