Quickscan Benchmark · August 2026

Web security benchmark: how do public websites score?

We ran the Guardian360 Quickscan against 12,914 public domains across the Netherlands, Belgium, Germany, France and beyond. Each domain gets a score from 0 to 100 based on its security headers, Content Security Policy, common misconfigurations, SPF and SSL/TLS setup. The average is 68.6: a reasonable baseline, but with the same high-value gaps turning up almost everywhere.

The biggest gaps are also the cheapest to close: security headers, a Content Security Policy and TLS hardening give the most security for the least effort.

Key findings

  • Missing security headers are the rule, not the exception: around 60% of domains have no X-Frame-Options header and about half lack a correct HSTS setting.
  • A Content Security Policy is missing on 73.2% of domains, the single most common shortcoming across every country.
  • Three quarters of domains (75.6%) have at least one SSL/TLS vulnerability, such as outdated protocols or weak ciphers.
  • The basics are largely in order: serious misconfigurations like an exposed PHPinfo page (1.6%) or an active HTTP TRACE method (0.9%) are rare.
  • Clear country differences: Belgium leads with 72.7, the Netherlands (68.9) and Germany (68.4) track the average, and France trails at 64.3.

About this benchmark

The Quickscan is an automated, non-intrusive scan of the publicly accessible side of a website. This benchmark aggregates 12,914 successfully completed scans into a market picture, so distributors, partners and clients can see how a single domain compares to the wider market and to other countries. Domains are attributed to a country by the country code in their top-level domain; generic extensions such as .com and .eu are counted in the overall benchmark. Curious how your own domain scores?
