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

Guardian Doors is a family-run business established in 1979 specializing in manufacturing, installing, maintaining, and repairing industrial and commercial door systems. The company operates nationwide from a base in south-east England and offers a 24/7 emergency repair service. Their market position is supported by multiple certifications including ISO 9000 and Constructionline, reflecting a strong commitment to quality and safety. The website presents a professional image with clear navigation and comprehensive product offerings targeting industrial, commercial, and domestic customers. Technically, the website uses modern JavaScript frameworks and tools such as UKit, Google Tag Manager, Hotjar, and Tawk.to for live chat and analytics. The site is mobile-optimized and accessible, with good SEO practices. However, some security best practices like security headers and cookie consent mechanisms are missing, which could be improved to enhance compliance and security posture. Security-wise, the site enforces HTTPS and does not expose sensitive data or vulnerable libraries. The absence of WHOIS data for the domain is a concern, reducing trust in domain legitimacy despite the professional business presence. No incident response or vulnerability disclosure information is provided, indicating room for improvement in transparency and security readiness. Overall, Guardian Doors presents a credible and professional business website with solid content and technical implementation but would benefit from enhanced security headers, privacy compliance features, and clearer domain registration transparency to improve 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

7 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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

  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 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';…

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

Guardian Doors operates in the manufacturing and retail sectors, focusing on industrial and commercial door solutions. Their competitive advantage lies in their long-standing market presence since 1979, ISO 9001 accreditation since 1992, and a comprehensive service offering including emergency repairs and planned maintenance. The business model combines product manufacturing with service contracts, targeting a broad audience from industrial clients to domestic customers. The company leverages social media channels for marketing and customer engagement. Growth indicators include a wide product range and certifications that support trust and quality. The partnership ecosystem includes social media platforms and analytics providers but no direct business partners or subsidiaries were identified from the website data.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible vulnerabilities in the HTML content. However, the lack of security headers such as Content-Security-Policy and absence of a cookie consent mechanism indicate gaps in security best practices and privacy compliance. No incident response or vulnerability disclosure policies are published, which limits transparency and preparedness for security incidents. The missing WHOIS data for the domain raises concerns about domain registration legitimacy. Overall, the security posture is adequate for a commercial website but could be significantly improved by implementing recommended headers, privacy features, and publishing security policies.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner and explicit cookie policy to comply with GDPR and improve user privacy transparency.
  3. Publish an incident response policy and vulnerability disclosure program to demonstrate security readiness and encourage responsible reporting.
  4. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to ensure they comply with privacy standards and do not introduce vulnerabilities.

Technical notes

Notes

The website is built using the UKit front-end framework with extensive use of JavaScript for interactivity and analytics integration. It employs Google Tag Manager and Hotjar for user behavior tracking and Tawk.to for live chat support. The site is mobile responsive and optimized for accessibility with clear navigation and structured content. Performance is moderate, with asynchronous loading of scripts to improve speed. No CMS or hosting provider details were detected. The technical implementation is modern but could benefit from enhanced security configurations and privacy compliance features.
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.
