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. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

UNOS holds a leading position in the healthcare nonprofit sector focused on organ donation and transplantation. Their business model revolves around managing the national organ transplant system, supported by technology solutions and advocacy efforts. The organization targets multiple stakeholders including organ donors, transplant patients, and medical professionals. Their long domain history and consistent WHOIS data reinforce their credibility. The website's content and structure support their mission effectively, with clear navigation and rich resources. Partnerships and related service domains indicate a robust ecosystem supporting their operations.

Security posture

The website employs HTTPS and uses security best practices such as clientTransferProhibited domain status and reCAPTCHA on forms. However, DNSSEC is not enabled, and common security headers like Content-Security-Policy and X-Frame-Options are not confirmed, representing areas for enhancement. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of a published security policy or vulnerability disclosure page suggests room for maturity in incident response and transparency. Overall, the security posture is good but could benefit from additional hardening and formalized policies.

Recommendations

  1. Enable DNSSEC to secure domain name resolution and prevent DNS spoofing.
  2. Implement and publish a comprehensive security policy and incident response contact information.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve browser security.
  4. Publish a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit and update third-party scripts and plugins to mitigate risks from vulnerabilities.

Technical notes

Notes

The website is built on WordPress with the Divi theme, leveraging jQuery and various third-party analytics and marketing scripts. The use of Google Tag Manager, Facebook Pixel, Hotjar, and Bing Ads indicates a mature marketing and analytics infrastructure. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. Hosting details are limited but the domain registrar is Network Solutions, LLC. The site uses modern fonts and asynchronous script loading to optimize user experience. Technical risks include reliance on multiple third-party scripts and lack of DNSSEC.
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.
