Founder's post from Barrion 🚀

Hey, I'm Mikael, founder of Barrion.

I spent years in engineering teams where security was the thing we all agreed mattered, then kept losing to whatever was actually on fire that week. No dedicated AppSec hire, no time to run a real audit, so vulnerabilities just... sat there. Barrion is the tool I wish we'd had: point it at your web app, and in under 60 seconds it runs 35+ automated checks across headers, TLS, DNS, CORS, and your JavaScript libraries, then hands you a fix report you can actually act on.

What makes us different is we don't stop at "here's what's broken." Every finding comes with a step-by-step remediation, and if you connect GitHub, Barrion can generate the fix as a pull request directly in your repo. No security background required, no manual research, just a scan-to-shipped-fix loop that fits into how engineering teams already work. Add continuous monitoring with Slack, Teams, or email alerts, and you've got a security posture that doesn't rely on remembering to check.

Launching on AppSumo is exciting because it puts Barrion in front of exactly the people we built it for: small teams, agencies, and developers who know security matters but don't have the headcount to hire for it. That's the whole reason we started this company, and getting to help this many builders lock down their apps at once is a genuinely great feeling.

Cheers! 
Mikael
