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

Stoneguard Projects Limited is a specialist building envelope contractor based in the United Kingdom, with a history dating back to 1963. The company focuses on façade restoration, maintenance, cladding, and structural framing services, targeting construction industry clients and property managers. The website presents a professional image with clear service offerings and contact information, supporting its market position as an established specialist contractor. Technically, the website employs modern front-end technologies including Bootstrap, jQuery, and Google Tag Manager for analytics. The site is mobile-optimized and features multimedia content, though some accessibility features could be improved. Security posture is moderate with HTTPS usage implied but lacking visible security headers and formal privacy or cookie policies, indicating room for compliance enhancements. The WHOIS data for the domain is unavailable due to an error indicating the domain name is invalid per Nominet UK rules, which raises concerns about domain legitimacy or possible misconfiguration. Despite this, the website content and contact details suggest a legitimate business presence. Overall, the site scores well on content quality and business credibility but needs improvements in privacy compliance and security best practices. Strategic recommendations include implementing comprehensive privacy and cookie policies, adding security headers, publishing vulnerability disclosure information, and resolving domain registration inconsistencies to enhance trust and compliance.

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

11 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.

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 8 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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

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

Stoneguard operates in the construction and building envelope sector, serving a niche market focused on façade restoration and cladding solutions. Their competitive advantage lies in their long-standing history since 1963 and specialization in high-quality building envelope services. The business model is service-oriented, targeting commercial and residential building owners and developers in the UK. Revenue streams likely derive from project contracts and maintenance agreements. The company maintains a professional online presence with LinkedIn integration, indicating engagement with industry networks. Growth indicators include a diverse service portfolio and multiple office locations. No parent or subsidiary companies were identified. Strategic observations suggest the company could benefit from enhanced digital compliance and clearer domain registration to strengthen market trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and no visible exposed sensitive data. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, limiting transparency and readiness. Privacy compliance is weak due to missing privacy and cookie policies, which may expose the company to regulatory risks under GDPR. The use of Google Tag Manager introduces moderate user tracking without clear data retention policies. Overall, the security culture appears basic, with opportunities to improve compliance, transparency, and technical defenses to better protect business and user data.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  3. Create and maintain a security.txt file or vulnerability disclosure page to facilitate responsible reporting.
  4. Verify and correct domain registration details to resolve WHOIS inconsistencies and improve legitimacy perception.
  5. Conduct regular security audits of third-party scripts and tracking tools to minimize vulnerabilities and privacy risks.

Technical notes

Notes

The website uses a modern front-end technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, Swiper for sliders, and Google Tag Manager for analytics. The site loads multimedia content such as videos and images efficiently, though performance is moderate rather than fast. Mobile optimization is good, with viewport meta tags and responsive CSS. Accessibility features are basic, with no explicit ARIA roles or landmarks detected. SEO is supported by meta description and keywords tags. No CMS or hosting provider information is evident from the HTML. Technical risks include lack of security headers and incomplete privacy compliance, which could impact user trust and regulatory adherence.
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.
