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

Aareon is a leading European SaaS provider specializing in property management systems designed to streamline operations for property owners and managers. Their platform integrates multiple facets of property management including payments, sustainability planning, and customer engagement, targeting a broad audience across residential and commercial real estate sectors. The website reflects a mature digital presence with professional design, clear navigation, and multimedia content that supports their market positioning. Technically, the site is built on the HubSpot CMS platform, leveraging modern JavaScript libraries and responsive design techniques to ensure good performance and accessibility. Security best practices such as HTTPS enforcement and security headers are implemented, though explicit security policies and incident response information are not publicly detailed. The absence of WHOIS data for the domain introduces some uncertainty regarding domain registration transparency, but the professional quality of the website and the presence of privacy and cookie policies indicate a legitimate business operation. No signs of WAF or content blocking were detected, and the site does not contain any adult or questionable content. Overall, Aareon demonstrates a strong business and technical foundation with room for improvement in transparency and security communication.

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, providing SaaS solutions for property management across Europe. Their business model focuses on delivering integrated software solutions that unify property, customer, and supplier data into a single platform. The company targets housing owners, managers, commercial property owners, and real estate users, emphasizing sustainability and customer experience. Their partnership ecosystem and localized sites indicate a broad European footprint. The lack of direct contact emails and phone numbers suggests a preference for controlled communication channels via contact forms. The company leverages HubSpot for marketing and analytics, supporting data-driven growth and customer engagement.

Security posture

The website employs HTTPS with strong SSL configuration and includes key security headers such as Content-Security-Policy and Strict-Transport-Security, indicating a good security baseline. Cookie consent mechanisms are in place, supporting GDPR compliance. However, the absence of a published security policy, incident response plan, or vulnerability disclosure reduces transparency and may impact trust from security-conscious stakeholders. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security posture is solid but could be enhanced by publishing explicit security documentation and providing direct security contact channels.

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. Provide direct security contact information such as a security@ or abuse@ email address.
  4. Enhance business credibility by including verified contact emails and phone numbers on the website.
  5. Regularly review WHOIS data and domain registration details to ensure transparency and reduce suspicion.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing modern front-end technologies including JavaScript libraries like Splide.js for carousels and htmx for dynamic content loading. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with efficient use of CDN-hosted assets and optimized images. SEO is supported by proper meta tags and Open Graph data. The technical infrastructure is robust and supports a professional user experience, though continuous monitoring for performance optimization and security updates is recommended.
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.
