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

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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

The London Clinic holds a leading market position as the UK's largest independent private hospital, targeting private patients and international clientele. Its business model includes direct pay, private medical insurance facilitation, and comprehensive health assessments. The presence of multiple specialist clinics and rapid diagnostics centers indicates a diversified service offering. Partnerships with insurance companies and integration of patient review platforms like Doctify enhance credibility and customer engagement. The organization’s charity status and reinvestment of surplus income reflect a commitment to quality and community. The website supports growth through clear calls to action, online enquiries, and multi-channel contact options.

Security posture

The website exhibits a mature security posture with HTTPS enabled and cookie consent managed via OneTrust, ensuring GDPR compliance. Use of Google Tag Manager and analytics scripts is controlled with consent settings. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The presence of a CQC widget and accreditation information adds trust. However, explicit HTTP security headers such as X-Frame-Options and X-Content-Type-Options were not explicitly found in the provided data and should be confirmed. Incident response contact information and vulnerability disclosure policies are not evident, suggesting areas for improvement in transparency and readiness.

Recommendations

  1. Verify and implement explicit HTTP security headers (X-Frame-Options, X-Content-Type-Options, Content-Security-Policy) to enhance protection against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  3. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.
  4. Enhance transparency by providing explicit data retention policies related to analytics and user data.
  5. Continue to maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Notes

The website is built on Drupal 10 CMS, indicating a modern and scalable content management platform. It integrates multiple third-party services including Google Analytics, Google Tag Manager, OneTrust for cookie consent, Monsido for accessibility and heatmaps, and Doctify for patient reviews. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with video backgrounds and rich media content balanced by efficient image loading strategies. The technical implementation supports strong SEO with proper meta tags and structured data. Hosting provider details are not explicit but the infrastructure supports secure HTTPS connections. Opportunities exist to enhance security headers and streamline third-party script management.
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.
