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

JLL is a global leader in real estate services, offering a comprehensive range of solutions including investment sales, leasing, property management, strategy, design, and sustainability consulting. The website targets investors, property owners, tenants, and corporate clients primarily in Germany but also globally through regional sites. The business model focuses on providing integrated real estate services supported by advanced technology and market insights. Technically, the site is built on Adobe Experience Manager with React components, leveraging modern analytics and consent management tools, ensuring a responsive and accessible user experience. Security posture is strong with HTTPS, security headers, and no visible vulnerabilities, although explicit security policies and incident response contacts are not published. Overall, the site is professional, trustworthy, and well-optimized, though WHOIS data is unavailable likely due to registry privacy policies, which does not detract from the site's legitimacy. Strategic recommendations include publishing security and incident response information and enhancing transparency around data protection contacts.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

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

JLL holds a strong market position as a global real estate services provider with a diversified portfolio of services catering to multiple sectors within real estate. Their competitive advantage lies in combining local market knowledge with global reach and technology-driven insights. Revenue streams likely include advisory fees, leasing commissions, property management fees, and capital markets transactions. The target customer segments include institutional investors, corporate occupiers, and property owners. Growth indicators include extensive regional site presence and continuous content updates such as market insights and client stories. The partnership ecosystem includes regional sites and investor relations platforms, supporting a robust operational footprint.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and use of reputable third-party services for analytics and consent management. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page, vulnerability disclosure program, and incident response contact information indicates room for improvement in transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies with consent mechanisms. Overall, the security maturity is good but could be enhanced by formalizing security governance documentation and communication.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and frameworks.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ emails.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance visibility of data protection officer contact information to improve GDPR compliance.

Technical notes

Notes

The website is built on a modern technology stack featuring Adobe Experience Manager CMS and React for dynamic components, ensuring a scalable and maintainable infrastructure. Performance is moderate with room for optimization, especially in image loading and script management. The site is highly mobile-optimized and accessible, with proper meta tags and SEO best practices implemented. Use of advanced analytics and consent management tools indicates a mature digital marketing and compliance approach. Technical risks are minimal but should be monitored continuously, especially regarding third-party dependencies and evolving security threats.
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.
