0–100, higher is better. How it is calculated

Pennine Stone Ltd. is a UK-based manufacturer specializing in architectural cast stone products, serving volume house builders, prestige builders, and construction companies across the UK. The company offers a comprehensive range of products including TecCast®, TecLite®, WetCast, and GRC, supported by a modern six-acre production facility and industry certifications. The website reflects a professional business with clear service offerings and industry memberships, positioning Pennine Stone as a leading supplier in its niche market. Technically, the website uses standard technologies such as jQuery and Twitter widgets, with moderate performance and basic mobile optimization. Security posture is adequate but could be improved by implementing security headers and explicit security policies. Privacy compliance is present with accessible privacy and cookie policies, though GDPR details could be enhanced. Overall, the website is trustworthy and professionally maintained, with no signs of blocking or suspicious activity.

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

5 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 company holds a strong market position as a foremost manufacturer of architectural cast stone in the UK, supported by ISO certifications and memberships in relevant industry associations. Its business model focuses on manufacturing and supplying both standard and bespoke cast stone products, targeting construction and building sectors. The website indicates a medium-sized enterprise founded in 2002, with a clear focus on quality and customer service. Partnerships with industry bodies and a professional web design agency further support its credibility. The absence of direct phone contact on the site may limit immediate customer engagement but is mitigated by contact forms and callback requests.

Security posture

The website demonstrates a moderate security maturity level with HTTPS implied but not explicitly confirmed. The presence of a cookie consent banner indicates awareness of privacy regulations. However, the lack of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security posture. No incident response or security policy information is provided, and no vulnerability disclosure or security.txt files are found. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site would benefit from enhanced security controls and transparency to improve trust and compliance.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, and X-Frame-Options to strengthen security posture.
  2. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  3. Enhance mobile optimization and accessibility features to improve user experience across devices.
  4. Add clear company phone contact information to facilitate direct customer communication.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a simple technology stack primarily based on jQuery and Twitter widgets, with CSS and JavaScript assets loaded from local paths. No CMS or advanced frameworks are detected, suggesting a custom or lightweight platform. Performance is moderate with no explicit indicators of optimization or CDN usage. SEO is basic with canonical links and meta titles present but no Open Graph or JSON-LD structured data found. Accessibility and mobile responsiveness are basic but could be improved. Hosting provider and SSL configuration details are not available from the provided data. Overall, the technical implementation is functional but could benefit from modernization and enhanced optimization.
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.
