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

Apleona GmbH is a leading European facility management company operating in 32 countries across the EMEA region. The company specializes in managing, decarbonizing, and modernizing real estate and technical installations, offering a broad portfolio of services including facility management, real estate management, building technology, interior construction, and digital green real estate solutions. With over 40,000 employees, Apleona positions itself as a market leader with a strong commitment to sustainability and innovation. Technically, the website is built on TYPO3 CMS and uses modern JavaScript libraries such as Swiper.js for interactive elements. The site is served over HTTPS with gzip compression, indicating a moderate to good performance and mobile optimization. However, some security best practices like DNSSEC and security headers are not implemented, which could be improved to enhance security posture. From a security perspective, the website uses HTTPS and has domain transfer protection enabled, but lacks explicit security policies, incident response contacts, and cookie consent mechanisms, which are important for GDPR compliance and user trust. No critical vulnerabilities or suspicious patterns were detected. The WHOIS data aligns well with the business claims, supporting legitimacy. Overall, the website is professional, content-rich, and trustworthy, but could benefit from enhanced security headers, explicit privacy and security policies, and cookie consent implementation to improve compliance and security posture.

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. 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

  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

Apleona operates as an essential entity in the real estate sector, focusing on integrated facility management services with a strong emphasis on sustainability and digital transformation. The company targets property owners, investors, and users across Europe, leveraging partnerships and acquisitions to expand its technical service offerings. Its business model revolves around providing comprehensive, innovative, and sustainable real estate solutions, positioning itself as a strategic partner for clients aiming for portfolio optimization and decarbonization. The company demonstrates growth through acquisitions and maintains a strong brand presence supported by sustainability certifications and active communication channels.

Security posture

The security maturity of the website is moderate. HTTPS is enforced, and domain transfer protection is enabled, which are positive indicators. However, the absence of DNSSEC, security headers (such as CSP, HSTS, X-Frame-Options), and explicit security or incident response policies limits the overall security posture. There is no visible vulnerability disclosure or security.txt file. The lack of a cookie consent mechanism also presents a compliance gap under GDPR. While no critical vulnerabilities were found, these gaps suggest room for improvement in security governance and transparency.

Recommendations

  1. Implement DNSSEC to enhance DNS security and prevent spoofing.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish explicit security policy and incident response information on the website.
  4. Introduce a cookie consent banner/mechanism to comply with GDPR requirements.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.

Technical notes

Notes

The website uses TYPO3 CMS, a robust enterprise content management system, combined with modern JavaScript libraries like Swiper.js for UI components. The site employs gzip compression and serves content over HTTPS, contributing to moderate performance and security. Mobile optimization is good, and SEO practices such as meta tags and hreflang attributes are properly implemented. However, accessibility features appear basic and could be enhanced. The hosting and domain registration are managed by reputable providers, supporting reliability. Overall, the technical infrastructure is solid but could benefit from additional security hardening and accessibility improvements.
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.
