Introduction to secureFlows (Video)
A short, non-technical video: why secureFlows exists and who it is for — the problem it solves, explained without jargon.

None of the app-security failures below involved sophisticated hacking. Real incidents from 2025–2026, and the handful of access-control patterns behind almost all of them.

The most common bug, and the easiest to understand: what it is, how it happens in practice, a press example, and a 5-minute test to check if it's happening in your app.
