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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Aareon operates in the real estate and technology sectors, focusing on B2B software solutions for social housing landlords, property managers, and related stakeholders. Its business model revolves around providing integrated digital platforms that streamline property management and tenant engagement. The company benefits from a broad European footprint and a partner ecosystem that enhances its market reach. The presence of multiple product lines and subsidiaries indicates diversified revenue streams and a strategic approach to market segmentation. The website's content and branding reinforce its market leadership and commitment to innovation in housing management.

Security posture

The website exhibits a mature security posture with enforced HTTPS, presence of key security headers, and no visible exposure of sensitive data. However, the absence of a published security policy, vulnerability disclosure program, or incident response contacts suggests areas for improvement in transparency and readiness. Cookie consent mechanisms and privacy policies align with GDPR requirements, indicating good data protection practices. No vulnerabilities or outdated libraries were detected in the analysis. Enhancing accessibility and publishing explicit security documentation would further strengthen the security culture and compliance.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance website accessibility features to meet higher standards and improve user experience for all users.
  4. Provide direct contact information for security incidents or data protection officer to comply with best practices.
  5. Regularly audit third-party scripts and tracking pixels to ensure privacy compliance and minimize user tracking.

Notes

The website is hosted on HubSpot CMS, utilizing modern JavaScript libraries such as Splide.js for carousels and HTMX for dynamic content loading. Google Tag Manager and Google Analytics 4 are integrated for analytics and marketing purposes. The site demonstrates good mobile responsiveness and SEO optimization with proper meta tags and Open Graph data. Performance is moderate, with video and image assets optimized for various screen sizes. The technical stack is modern and well-maintained, though opportunities exist to improve accessibility and reduce tracking footprint for enhanced privacy.
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.
