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

Nassau University Medical Center (NUMC), operating under the NuHealth system, is a large healthcare provider and teaching hospital located in East Meadow, New York. Established in 1935, it serves as the primary medical care source for Nassau County. The website presents a comprehensive range of healthcare services including maternity, bariatric surgery, mental health, emergency care, and primary care, targeting patients, visitors, and medical professionals. The institution maintains a strong market position with multiple centers of care and community partnerships. Technically, the website is built on WordPress with modern frameworks like Bootstrap and integrates Google Analytics and Tag Manager for tracking. It supports multiple languages via GTranslate and implements Google reCAPTCHA for form security. Security posture is good with HTTPS enforced and no visible vulnerabilities, though security headers are not explicitly detected. Privacy compliance is basic, with a privacy policy present but lacking explicit cookie consent mechanisms. WHOIS data is missing, which reduces domain transparency but the website content and external references strongly support legitimacy. Overall, the site is professional, secure, and user-friendly, with room for improvement in privacy and security disclosures.

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

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.

    • 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. 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

NUMC operates in the healthcare sector as an essential entity providing a wide array of medical services and education. Its business model focuses on patient care, medical education, and community health services. The institution benefits from a strong brand presence and partnerships such as Harmony Healthcare Long Island. Revenue streams likely include patient services, government funding, and donations. The target audience includes local residents, patients requiring specialized care, medical students, and healthcare professionals. The website's content and structure indicate a mature digital presence with ongoing updates and community engagement. Strategic observations include the need to enhance privacy compliance and security transparency to align with evolving regulatory requirements.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms from abuse. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap that could be addressed to improve defense-in-depth. There is no published security policy or incident response contact information, which limits transparency in security governance. The missing WHOIS data is a concern for domain trust but does not directly impact website security. Overall, the site is secure but could benefit from enhanced security disclosures and technical headers.

Recommendations

  1. Implement and publish a comprehensive security policy including incident response contacts.
  2. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Introduce a clear cookie consent banner to comply with GDPR and other privacy regulations.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Regularly audit third-party scripts and plugins for security vulnerabilities and update them promptly.

Technical notes

Notes

The website is built on WordPress CMS with Bootstrap framework for responsive design. It uses Google Analytics and Tag Manager for tracking user interactions and MonsterInsights plugin for analytics integration. The site supports multiple languages via GTranslate and employs Google reCAPTCHA for form security. Performance is moderate with caching and minified assets in use. Accessibility features are present, including an accessibility widget. SEO is enhanced by Yoast SEO plugin with proper meta tags and structured data in JSON-LD format. The site is mobile optimized and has clear navigation. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring. Hosting provider details are not explicitly identified from the 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.
