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

7 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 positions Stephanie Eckles as a recognized expert in front-end development and CSS, leveraging multiple popular projects and educational platforms. The business benefits from a diversified content portfolio including tutorials, video courses, podcasts, and workshops. The target audience includes developers seeking modern CSS techniques and accessibility best practices. The site’s presence on GitHub with significant stars and active social media channels supports community trust and engagement. Revenue streams likely include sponsorships, paid courses, and speaking fees. The ecosystem includes partnerships with platforms like egghead.io and Smashing Magazine. Growth indicators include upcoming speaking events and active content updates.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible sensitive data leaks. However, the lack of published privacy and cookie policies, absence of security headers, and no incident response or vulnerability disclosure information represent compliance and security gaps. The use of plausible.io analytics aligns with privacy-conscious practices but overall GDPR compliance is not clearly demonstrated. No WAF or blocking mechanisms are detected, and no suspicious or malicious content is present. The domain registration is consistent and trustworthy, supporting the site's legitimacy.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance security posture.
  3. Enable DNSSEC on the domain to protect against DNS spoofing.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure and incident response.
  5. Consider adding explicit contact emails or phone numbers for business and security inquiries to improve transparency.

Technical notes

Notes

The website is built on a modern static site generator (Eleventy) with a clean, semantic HTML structure and well-optimized CSS. It uses Sass for styling and integrates privacy-focused analytics via plausible.io. The site is mobile responsive and accessible, with good SEO metadata including Open Graph and Twitter Card tags. Hosting details are not explicit but likely use a static hosting provider such as Netlify. No CMS or dynamic backend detected, reducing attack surface. Performance is fast with preloading of fonts and minimal external dependencies. Technical risks are low, but the absence of security headers and formal privacy documentation are areas for improvement.
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.
