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

Principal Medical is a UK-based healthcare provider focused on delivering integrity and innovation in healthcare services. The company offers general practice, community services, membership support, and patient feedback mechanisms, positioning itself as a trusted healthcare partner in the UK market. The website reflects a professional and consistent brand image, targeting healthcare providers and patients. Technically, the site is built on WordPress with modern plugins such as Yoast SEO, Gravity Forms, and LayerSlider, indicating a mature digital infrastructure. The site is mobile optimized and uses HTTPS, ensuring secure communications. Security posture is good with no visible vulnerabilities, though security headers could be improved. Privacy compliance is partial, with a cookie consent mechanism present but no explicit privacy or terms policies found on the homepage. WHOIS data is unavailable due to a domain naming rules violation, which raises some concerns about domain legitimacy. Overall, the site is professional and trustworthy but would benefit from enhanced transparency and security documentation.

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. 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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 26 days

      What to do: Renew domain registration before expiration

  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 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';…

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 company operates in the healthcare sector, providing essential services such as general practice and community healthcare. Its business model includes membership support, indicating recurring revenue streams and community engagement. The presence of federation and staff subdomains suggests a structured organizational ecosystem. The company appears medium-sized with a focus on UK healthcare markets. The website's content and design indicate a well-established market position with trust signals like a 'Good' CQC rating. However, the lack of visible contact details and privacy policies may limit user trust and regulatory compliance. The company likely targets healthcare professionals and patients seeking reliable healthcare services.

Security posture

The website demonstrates a good security posture with HTTPS enabled and no exposed sensitive data in the HTML content. The use of reputable WordPress plugins and the absence of suspicious external domains reduce the risk of vulnerabilities. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. No incident response or security policy information is publicly available, which could hinder rapid response to security incidents. The WHOIS data anomaly is a concern but does not directly impact website security. Overall, the site is secure but could improve transparency and technical security controls.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Add and configure security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Provide clear contact information including company emails and phone numbers to improve business credibility and user support.
  4. Publish security and incident response policies or contacts to demonstrate preparedness and transparency.
  5. Investigate and resolve the WHOIS domain naming issue to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website is built on WordPress 6.9.4 with PHP 7.4.33, using modern plugins such as Yoast SEO for search optimization, Gravity Forms for form handling, and LayerSlider for rich content presentation. It uses Google Fonts and FontAwesome for styling and icons, and integrates Google Maps API for location services. The site is mobile optimized with responsive design and uses HTTPS with a presumably valid SSL certificate. Performance is moderate, with no major issues detected in the HTML content. Accessibility is basic, with some ARIA attributes and semantic HTML present. SEO is good with canonical tags, Open Graph metadata, and JSON-LD structured data for enhanced search engine understanding. Hosting provider details are not explicitly found. Overall, the technical infrastructure is solid but could benefit from enhanced accessibility and security header implementation.
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.
