This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website targets frontend developers and web professionals interested in modern CSS techniques, positioning itself as an expert resource in this niche. Its business model centers on content publishing, educational resources, and community engagement through newsletters and social media. Revenue streams include advertising and voluntary support via Buy Me a Coffee. The site benefits from strategic partnerships with related domains like ThinkDoBeCreate and SmolCSS. Growth indicators include a comprehensive article archive, video resources, and planned interactive challenges. The author’s reputation and endorsements from industry figures enhance credibility. The site’s operations reflect a focused, small-scale content business with a strong digital presence and community orientation.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. The absence of explicit security headers such as Content Security Policy (CSP), HSTS, or X-Frame-Options represents an area for improvement. No forms collect personal or sensitive data, reducing attack surface. Minimal user tracking via Plausible Analytics aligns with privacy-conscious practices, though the lack of privacy and cookie policies is a compliance shortfall. Incident response and security policy documentation are not present. Overall, the site is secure for its purpose but would benefit from enhanced security headers and formalized privacy compliance.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR and privacy compliance.
  2. Add a cookie consent mechanism if cookies or tracking scripts are used to comply with privacy regulations.
  3. Configure and deploy security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen security posture.
  4. Consider adding a security.txt file or incident response contact information to improve transparency and readiness.
  5. Maintain regular security audits and update dependencies to avoid potential vulnerabilities.

Technical notes

Notes

The website is built on a modern static site generator (Eleventy), ensuring fast performance and ease of maintenance. The tech stack includes HTML5, CSS3, JavaScript, and SVG icons, with evidence of Sass usage. The site is well-optimized for mobile devices and accessibility, with semantic HTML and ARIA attributes. SEO is supported by proper meta tags, Open Graph tags, and canonical URLs. External resources are loaded asynchronously to improve performance. Advertising and analytics scripts are limited and privacy-conscious. No CMS or dynamic backend is detected, reducing complexity and attack surface. Opportunities exist to enhance hosting provider transparency and implement advanced security headers. Overall, the technical implementation is robust, modern, and aligned with best practices for content-focused websites.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
