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

Sirius Facilities GmbH is a prominent German commercial real estate company specializing in flexible leasing of office spaces, storage, production halls, conference centers, and virtual office services. With over 70 locations and a large portfolio, they cater primarily to small and medium-sized enterprises as well as larger firms. Their website demonstrates a mature digital presence with a professional design, comprehensive service offerings, and multiple contact channels. Technically, the site is built on Drupal CMS with modern JavaScript libraries and includes privacy compliance tools such as Usercentrics CMP and analytics via Google Analytics and Matomo. Security posture is strong with HTTPS and secure forms, though some HTTP security headers could be improved. The WHOIS data is unavailable, which slightly impacts trust but the overall business credibility remains high due to consistent branding and transparent contact information.

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. 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';…

  2. 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

    • 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

The company holds a strong market position in the German real estate sector, focusing on revitalizing industrial spaces into modern business parks. Their business model revolves around leasing diverse commercial spaces with added services like conference rooms and virtual offices. The presence of partner portals and job sites indicates a well-structured ecosystem. Customer testimonials and detailed location data reinforce their credibility. The target market includes SMEs and larger enterprises seeking flexible and scalable workspace solutions. Their sustainability efforts are highlighted via Tree-Nation integration and linked compliance policies.

Security posture

The website employs HTTPS and uses a consent management platform to comply with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the use of older jQuery versions suggests a need for library updates to mitigate potential risks. The absence of explicit security headers like CSP or HSTS is a minor gap. No incident response or security policy pages were found, which could be improved to enhance transparency. Overall, the security posture is solid but could benefit from incremental enhancements.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy and Strict-Transport-Security.
  2. Upgrade JavaScript libraries such as jQuery to the latest secure versions.
  3. Publish a security.txt file to facilitate vulnerability reporting.
  4. Enhance accessibility features to meet WCAG standards.
  5. Regularly audit third-party scripts and tracking tools for privacy compliance.

Technical notes

Notes

The website is powered by Drupal 7.60 with Bootstrap for responsive design and jQuery 1.8 for interactivity. It integrates several third-party scripts including Usercentrics for consent management, Matomo and Google Analytics for tracking, and Tree-Nation for sustainability impact. The site loads multiple CSS and JS assets, indicating moderate complexity. Performance is moderate with room for optimization. Mobile optimization is good, and SEO practices are evident through meta tags and structured data. The site lacks some modern security headers and uses somewhat outdated JavaScript libraries, which could pose risks if not updated.
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.
