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

Culligan UK Limited operates a professional website offering a wide range of water dispensers and hydration solutions tailored for businesses and residential customers in the United Kingdom. The company positions itself as a trusted provider with a strong market presence, serving over 20,000 companies daily and boasting a high customer satisfaction rating. Their services include bottled water coolers, mains-fed water coolers, instant boiling and chilled taps, hospitality systems, and related accessories. The website is well-branded, content-rich, and optimized for user experience and SEO. Technically, the website is built on WordPress using modern frameworks such as Bootstrap and integrates multiple analytics and marketing tools including Google Analytics, Piwik PRO, Visual Website Optimizer, and Trustpilot widgets. The site is mobile-optimized and demonstrates good performance and accessibility standards. Security measures include HTTPS enforcement and use of Google reCAPTCHA on forms, although some security headers could be improved. The security posture is solid with no evident vulnerabilities in the provided content, but the absence of a public security policy or incident response contact is noted. Privacy and cookie policies are present with consent mechanisms, indicating compliance with GDPR requirements. The WHOIS lookup failed due to an invalid query for the subdomain rather than the registered domain, but the website's legitimacy is supported by branding and trust signals. Overall, Culligan UK Limited presents a professional, trustworthy online presence with strong business credibility and a good security baseline. Strategic improvements in security headers and public security disclosures would enhance their security posture further.

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

Culligan UK Limited is positioned as a leading provider of hydration solutions in the UK market, targeting both commercial and residential sectors. Their business model combines product sales and rental services, supported by a strong service and support infrastructure. The company leverages partnerships and a broad product portfolio to maintain competitive advantage. Their customer base includes large enterprises and well-known brands, indicating strong market penetration. The website's integration of customer reviews and partner logos supports credibility and trust. Growth indicators include active marketing and analytics usage, as well as a comprehensive product range tailored to diverse sectors such as hospitality, education, healthcare, and construction.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms. Analytics and marketing scripts are loaded asynchronously with integrity attributes where applicable. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No public security policy or incident response contact was found, which could hinder vulnerability reporting and incident management. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security posture is good but could be enhanced by adopting additional HTTP security headers and publishing a security policy.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a public security policy and provide clear incident response contact information.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance server-side validation and monitoring of form inputs to prevent abuse.

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.
