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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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

  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 Plexus network occupies a strategic position in the regional healthcare sector, leveraging collaboration among multiple hospitals to optimize care delivery. Its business model centers on integrated care and quality assurance, supported by digital tools like Nexuzhealth. The presence of multiple partner hospital domains and official branding indicates a stable partnership ecosystem. While no direct revenue or financial data is available, the network's approval for regional care plans suggests governmental recognition and funding. The target audience includes patients, healthcare professionals, and regional care partners.

Security posture

The website employs HTTPS and modern CMS technology (Drupal 9), with embedded analytics tools such as Google Tag Manager and Plausible Analytics. However, no explicit security headers were detected in the HTML content, and no privacy policy page was found, which are gaps in compliance and security best practices. The WHOIS data is restricted due to registry policy, limiting transparency but not necessarily indicating risk. No contact information for incident response or data protection officers is provided. Overall, the security posture is moderate but could be improved by adding security headers, privacy policies, and incident response contacts.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a comprehensive privacy policy page detailing data collection, processing, and user rights to improve GDPR compliance.
  3. Add explicit cookie consent mechanisms that require user interaction to comply with privacy regulations.
  4. Provide clear contact information for security incidents and data protection officer to enhance trust and incident response readiness.
  5. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website is built on Drupal 9, a modern and widely used CMS, indicating a solid technical foundation. It uses Typekit for fonts and integrates Google Tag Manager and Plausible Analytics for tracking and analytics. The site is mobile optimized with responsive design and clear navigation. Performance is moderate, with no major errors or broken elements detected. However, the absence of security headers and explicit privacy policies suggests room for technical improvements in security and compliance. Hosting provider details are not evident from the HTML content.
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.
