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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Treforest Tiling Ltd holds a strong regional market position as a roofing service provider to housing developers in South Wales. Their competitive advantage lies in their long-standing experience, skilled workforce with recognized certifications (CSCS, NVQ), and comprehensive service offerings including solar installations. The business model focuses on B2B service delivery within the construction sector, targeting developers and contractors. The company invests in health and safety and apprenticeship programs, indicating growth and sustainability focus. Their digital presence is professional but limited in marketing automation or analytics, suggesting opportunities for digital growth. Partnerships appear limited to their website builder (BWAR!) and social media channels. The company maintains transparency with clear contact details and policies, enhancing credibility.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and a cookie consent banner compliant with GDPR is implemented, reflecting privacy awareness. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No incident response or security policy pages are present, which could hinder transparency and preparedness. No vulnerable or outdated libraries were detected in the HTML content. The site does not expose sensitive data or credentials. Overall, the security posture is adequate for the business type but could be improved by implementing recommended headers, publishing security policies, and conducting regular security assessments.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  3. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and maintain security hygiene.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Consider integrating analytics and marketing tools with privacy-respecting configurations to better understand user behavior and improve digital marketing.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Yootheme theme and UIkit framework, providing a responsive and visually appealing design. The hosting is provided by Fasthosts Internet Ltd, a reputable UK hosting provider. Performance is moderate with optimized images and lazy loading techniques. The site includes a cookie consent plugin that categorizes cookies and manages user preferences effectively. No heavy analytics or advertising scripts were detected, which reduces page load and privacy concerns. The site uses standard HTML5 and CSS3 with inline styles and external stylesheets. JavaScript libraries are limited to UIkit and cookie consent scripts, minimizing attack surface. Overall, the technical infrastructure is sound but could benefit from enhanced security headers and accessibility improvements.
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.
