Automate Website Security Audits with Technology Detection in Python

Knowing what technologies a website runs is the first step in any security assessment. Outdated CMS versions, exposed server headers, legacy JavaScript libraries — these are all attack vectors, and they're all detectable. In this tutorial, we'll build a Python tool that scans any website, identifies its technology stack, and flags potential security concerns based on what it finds. Why Technology Detection Matters for Security Most security audits start with reconnaissance. Before testing for vulnerabilities, you need to know what's running. A site using WordPress 5.x has a different risk profile than one running Next.js on Vercel. Manually checking this is tedious. Browser extensions work for one site at a time but don't scale. We'll automate it with an API that detects 141+ technologies programmatically. Setup We'll use the Technology Detection API on RapidAPI.
