Most security software marketing sounds the same: "military-grade encryption," "unbreakable," "100% secure." I want to try something different. I'm going to tell you about a real mistake in an earlier version of my app, ATLOCK, how I found it, and exactly what replaced it — because I think more builders should talk about the version of their product they're embarrassed by.

What ATLOCK actually does

ATLOCK is a Windows security suite with four modules:

Lockdown — system-level screen lock with a countdown timer and OS hardening

File Guard — locks files at the NTFS ACL level, so they're genuinely unreadable, not just hidden
