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

Jefferson is a large integrated enterprise focused on healthcare, education, and insurance services primarily serving Pennsylvania and New Jersey. The website presents a professional and consistent brand image highlighting its three main business units: Jefferson Health, Thomas Jefferson University, and Jefferson Health Plans. The site targets residents, students, patients, and insurance customers in the region. Technically, the site is built on Adobe Experience Manager with modern analytics tools like Google Tag Manager and Adobe Data Layer, offering good mobile optimization and SEO practices. Security posture is solid with HTTPS and no visible vulnerabilities, though security headers and privacy policies are lacking. WHOIS data is privacy protected, which is reasonable for this type of organization. Overall, the site is trustworthy and well-maintained but could improve transparency around privacy and security policies.

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

9 findings rated critical or high. Fix these first.

  1. 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

  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 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 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

    • 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

Jefferson holds a strong market position as the second largest employer in Philadelphia with a multifaceted business model integrating healthcare delivery, higher education, and health insurance. Its revenue streams likely include patient services, tuition and research funding, and insurance premiums. The target customer segments include patients, students, and insured individuals in Pennsylvania and New Jersey. The organization maintains a partnership ecosystem including donation platforms and career portals. Growth indicators include community impact initiatives and expansion into events like the Jefferson Lehigh Valley Classic. The website content and linked domains reinforce a cohesive enterprise brand with clear strategic focus.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and use of reputable analytics frameworks. However, the absence of security headers such as Content-Security-Policy and lack of visible privacy and cookie policies indicate gaps in compliance and best practices. No vulnerability disclosures or incident response contacts are provided, which could hinder rapid response to security events. No exposed sensitive data or vulnerable libraries were detected. Overall, the security risk is moderate with room for improvement in transparency and header implementation.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to enhance GDPR and privacy compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  3. Provide clear contact information for security incidents and designate a Data Protection Officer to improve incident response readiness.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website is built on Adobe Experience Manager, leveraging client libraries and modern JavaScript frameworks including jQuery. Google Tag Manager and Adobe Data Layer are used for analytics and marketing tracking. The site is mobile optimized with responsive images and layout. Performance is moderate with no critical errors detected. However, the absence of security headers and privacy-related pages indicates technical debt in compliance and security best practices. Hosting provider details are not disclosed. Overall, the technical infrastructure supports a professional enterprise website but could benefit from modernization in security and privacy implementations.
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.
