As answered by people managing WebscanRadar and Security Headers.
WebscanRadar's answer
Most free scanners check only one thing – SSL, headers or cookies. WebscanRadar combines security and GDPR compliance in one scan: SSL/TLS, security headers, cookie consent, email security (SPF/DKIM/DMARC), DNS and open ports. Every finding comes with a clear explanation and concrete fix instructions, not just a red flag.
WebscanRadar's answer
One scan instead of five different tools. No signup, results in seconds, plain-language explanations and fix instructions, a PDF report to share with your developer or agency, and an embeddable badge. Hosted in the EU (Austria) – your scan data never leaves Europe.
WebscanRadar's answer
Small and medium-sized businesses, freelancers and web agencies in Europe who want to check their website's security and GDPR compliance quickly – without being security experts. Also developers who need a fast overview before a launch or audit.
WebscanRadar's answer
WebscanRadar was built by an independent developer in Vienna, Austria. While working on websites for small businesses, it became clear that existing tools either check only one aspect or are built for security professionals. The goal was a single, free, understandable scan that covers both security and GDPR – hosted in Europe.
WebscanRadar's answer
Python, Flask, SQLite, Redis, Playwright (headless browser for cookie and consent checks), nginx – self-hosted on Hetzner servers in the EU.
