Hi Product Hunt! 👋 I'm the maker of ASM Scan. After years in application security and penetration testing, I kept seeing the same issue: most organizations don't have a complete view of what they're exposing on the internet. Startups and small teams, especially those moving fast with AI-assisted or "vibe" coding, often deploy services, leak secrets, expose ports, or run vulnerable software without realizing it. Enterprise ASM platforms exist, but they're often expensive and out of reach for smaller teams. That's why we built ASM Scan. Our approach is **99% passive and 1% targeted active validation**. We first collect public intelligence—DNS, certificate transparency, historical archives, JavaScript, technologies, repositories, and other internet signals—then perform minimal validation to reduce false positives and confirm what's actually exposed. Instead of overwhelming you with noisy data, ASM Scan correlates everything into evidence-backed findings, including exposed assets, outdated technologies, leaked secrets, misconfigurations, takeover risks, and vulnerable software versions. **To help people get started, your first complete external attack surface scan and report are 100% free.** No credit card required. I'd love your feedback: * What findings would be most valuable to you? * What integrations would you like to see? * What would make ASM Scan part of your security workflow? Thanks for checking out ASM Scan—we're excited to hear what you think! 🚀
