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

Kingston Cleaning Services (KCS) is a UK-based commercial and industrial cleaning company specializing in a wide range of interior and exterior cleaning services across Yorkshire and the UK. The company serves diverse sectors including commercial, industrial, and domestic clients, offering services such as building fabric cleaning, window cleaning, pressure washing, and high-level cleaning. KCS emphasizes health and safety, with trained teams and strong site compliance, positioning itself as a reliable and reputable cleaning partner with over 70 years of combined experience in the industry. Technically, the website is built on WordPress with modern SEO and analytics tools such as Yoast SEO and Google Analytics integrated. The site is mobile-optimized with good navigation and content structure, though some security headers could be improved. The website uses HTTPS and reCAPTCHA for form security, reflecting a moderate to good security posture. Security-wise, the site demonstrates good practices including HTTPS enforcement and no visible vulnerabilities or exposed sensitive data. However, it lacks explicit incident response contacts and a vulnerability disclosure policy, which are recommended for enhanced security maturity. Privacy and cookie policies are present and appear GDPR compliant, supporting privacy compliance. Overall, the website is professional, trustworthy, and well-maintained, though the WHOIS data is unavailable due to domain registration lookup issues. This does not detract from the legitimacy of the business, but it is recommended to verify domain registration details through alternative means. Strategic improvements in security headers and incident response transparency would further strengthen the security posture.

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. 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

  2. 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';…

  3. 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

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

KCS has evolved from a local window cleaning business to a medium-sized national cleaning service provider with a strong reputation for safety, quality, and value. Their business model focuses on service delivery across multiple sectors, including commercial, industrial, and domestic markets. The company leverages long-term client relationships and accreditations to maintain competitive advantage. Their growth is supported by a diverse service portfolio and geographic coverage across Yorkshire and the UK. The presence of client testimonials and accreditations enhances credibility. The company targets businesses requiring specialist cleaning services, emphasizing safety and compliance, which aligns with regulatory and client expectations in industrial and commercial sectors.

Security posture

The security maturity of the website is moderate to good. HTTPS is enforced, and reCAPTCHA is used to protect forms from abuse. However, some important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of an incident response contact or vulnerability disclosure policy limits the site's readiness for security incidents. Privacy policies are present and appear GDPR compliant, supporting data protection. Overall, the security posture is adequate for the business type but could be enhanced by implementing recommended headers and incident response transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to strengthen browser security.
  2. Add a publicly accessible vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Provide explicit incident response contact information on the website to improve transparency and readiness.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate risks from known vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO for search engine optimization, Google Tag Manager and Google Analytics for tracking, and reCAPTCHA for form security. The site uses multiple plugins such as Contact Form 7 and drag-and-drop file upload extensions. Performance is moderate with good mobile optimization and clear navigation. The site employs structured data (JSON-LD) for SEO and social media integration. Some technical debt is evident in partial implementation of security headers and lack of incident response mechanisms. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports the business needs but has room for security 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.
