Hi HN, I'm an Indie Dev. Building web apps, I struggled to check for vulnerabilities on a surface and a deeper level at the same time.

What really gets me excited about my work is making security easy and effective for developers and ops teams! In my last role, at one of the top 3 FinTechs, following the attack against Solarwinds, the CEO asked me what we are doing to secure our software supply chain. I met with 15+ vendors, did a few POCs, but unfortunately each solution either increased operational cost or was too…
