Low risk. 2 critical or high findings in Security headers and SSL/TLS.

Security score

83/100

Risk levelLow

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

JLL is a global leader in real estate services, offering a comprehensive portfolio of services including investment sales advisory, project management, asset management, and sustainability consulting. The company targets investors, property owners, and tenants across local, national, and international markets. Their website is professionally designed, localized for the German market, and demonstrates a strong commitment to privacy and compliance with GDPR. Technically, the site leverages Adobe Experience Manager as its CMS, integrates advanced analytics and consent management tools, and employs modern web technologies to ensure a responsive and accessible user experience. Security posture is robust with HTTPS enforcement, security headers, and cookie consent mechanisms, although explicit security policy and incident response information are not publicly detailed. The domain WHOIS data is unavailable, which reduces transparency but does not detract from the overall legitimacy given the brand's global presence. Strategic recommendations include publishing a dedicated security policy, incident response contacts, and a vulnerability disclosure program to enhance trust and compliance.

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

2 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. 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 operates in the real estate sector as an essential entity with an enterprise scale. Their business model focuses on providing integrated real estate solutions to a diverse clientele including investors and property owners. The company maintains a strong market position as a global leader with a wide range of services that address investment, management, and sustainability needs. Their digital presence is supported by a sophisticated technology stack and regional partner sites, such as the China-specific domain. The company demonstrates strong branding consistency and trust indicators including ISO 27001 certification and comprehensive privacy compliance. Growth indicators are supported by extensive content, localized language support, and a broad geographic footprint.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and integration of consent management tools like OneTrust. No obvious vulnerabilities or exposed sensitive data were detected in the content. However, the absence of a publicly accessible security policy and incident response contact information limits transparency. The domain's WHOIS data is not publicly available, which is a minor concern but may be due to privacy protection or registry policies. Overall, the security practices align well with industry standards, but improvements in transparency and vulnerability disclosure would strengthen the security culture and trustworthiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate reporting and response.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance WHOIS transparency if possible to improve domain trustworthiness.
  5. Continue to monitor and update third-party libraries and consent mechanisms to maintain compliance.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS platform, and integrates Datadog RUM for real user monitoring and Adobe Launch for tag management. Consent and cookie management are handled by OneTrust, ensuring GDPR compliance. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data. Performance is moderate, likely influenced by the complexity of the CMS and third-party integrations. No critical technical debt or vulnerabilities were identified, but ongoing maintenance of third-party scripts and security headers is recommended to sustain performance and security.
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.
