Best Security & Privacy for Mac.

Mac security apps cover the essentials macOS leaves to you: password managers, firewall monitors that show which apps phone home, camera and microphone guards, and encrypted storage. The best of them are transparent about their own behavior — several here are open source precisely so you can verify the tool guarding your data.

Start with a password manager if you don't have one; add an outbound firewall like a Little Snitch-style monitor if you want to see what your software actually does when you're not looking.
