Frequently Asked Questions

What is a technology stack detector? +
A tech stack detector analyzes a website to identify what technologies it uses — CMS (WordPress, Drupal), web servers (Nginx, Apache), programming languages (PHP, Python), JavaScript libraries (React, jQuery), CDN providers, and analytics tools.
How does technology detection work? +
We use WhatWeb fingerprinting combined with HTTP header analysis. We check for known signatures in server headers, cookies, HTML meta tags, CSS/JS file patterns, and framework-specific markup.
Why is knowing a tech stack useful for security? +
Knowing the tech stack helps identify potential attack vectors. Outdated CMS versions, known vulnerable libraries, or misconfigured servers are common entry points. Security teams use this for vulnerability prioritization and attack surface mapping.
Can websites hide their technology stack? +
Partially. Removing server headers and meta tags helps, but deep fingerprinting can still detect technologies through response patterns, URL structures, and default file locations. Security through obscurity is not a reliable defense.
