Download Additional Security Apps

If you have more advanced security needs, or you’re just a tech-savvy tinkerer, you can look into other Mac security apps. Security researcher Patrick Wardle of Objective-See actually creates and maintains an amazing array of free Mac security apps that can go a long way toward shoring up your defenses.

For example, there’s Lulu, a free Mac firewall that can detect and block malware on your system from connecting to the internet. Other options include OverSight, which can detect apps that are secretly recording you via microphone and webcam, and RansomWhere?, which protects your Mac from ransomware.
