About CoreLock
We started CoreLock because we were tired of security tools that were either too complicated for normal people or too dumbed-down to be useful. There had to be a middle ground.
Most people know they should care about their computer's security, but they don't know where to start.
We asked a simple question: What if your computer could explain its own security to you? Not in jargon-filled reports, but in plain English. What if it could tell you what's wrong and what to do about it?
That question became CoreLock: a Mac app that runs six security checks, gives you a 0 to 100 Security Score, and shows what it found on a few plain screens. No jargon. No complicated settings. When something needs changing, it takes you to the right place to change it.
Founder & Lead Developer
I built CoreLock because I kept running into the same problem: my parents, friends, and non-technical people in my life had no idea what was actually happening on their computers.
I wanted to build something that tells you what's going on in plain English, and points you to the fix.
CoreLock is a one-person project. I read every support email, fix every bug, and ship every update myself. If you have feedback or ideas, I genuinely want to hear them.
CoreLock isn't a side project — it's my full-time focus.
Six-check scan
Running apps, network, app permissions, login items, AI agents, and your Downloads folder
0 to 100 Security Score
Worked out on your Mac. A check that can't run shows as not checked, never as passed
Apple Notarized
Signed and notarized by Apple. Notarization is an automated check for known malware, not a guarantee of safety
Local-first

CoreLock shows what it found and which checks couldn't run. No black boxes, no hidden actions. Nothing is fixed automatically by default.
Security checks wrapped in an interface anyone can use. Technical depth when you want it, simplicity when you don't.
A generous free tier that actually works. Paid plans that are worth the price. No dark patterns, no surprise charges.
Here is what CoreLock actually checks:
