68/100

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

BUWOG Immobilien Treuhand GmbH operates in the real estate sector, providing property management and related services to tenants, property owners, and investors. The company positions itself as an important player within the German real estate market, with a professional online presence that targets a broad audience including tenants and investors. The website content is well-structured and professionally designed, reflecting a medium-sized enterprise with consistent branding and clear business focus. Technically, the website is hosted on Microsoft Azure infrastructure, utilizing Azure DNS and Cookiebot for cookie consent management. The site employs modern web technologies including JavaScript and CSS, and demonstrates good mobile optimization and SEO practices. However, some advanced security headers and explicit privacy policy documentation are missing, which could be improved to enhance compliance and security posture. From a security perspective, the website benefits from HTTPS encryption and a robust cookie consent mechanism, indicating awareness of GDPR and privacy requirements. No critical vulnerabilities or suspicious patterns were detected in the WHOIS data or website content. Nonetheless, the absence of explicit privacy policies, terms of service, and incident response contacts suggests room for improvement in transparency and user trust. Overall, the website presents a trustworthy and professional image with moderate technical maturity and compliance. Strategic enhancements in privacy documentation, security headers, and contact transparency would further strengthen its security posture and regulatory compliance.

NIS2 and GDPR posture

Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

BUWOG Immobilien Treuhand GmbH is positioned within the real estate sector, focusing on property management and services for tenants and investors. The company leverages partnerships with major real estate entities such as Vonovia and Deutsche Wohnen, as evidenced by multiple linked domains and cookie providers. The business model centers on trust and fiduciary services in real estate, targeting a German-speaking audience primarily in Germany. The website's digital presence supports this model with detailed service descriptions and a cookie consent framework aligned with GDPR. Growth indicators include integration with large real estate networks and use of modern hosting infrastructure. The partnership ecosystem is robust, involving multiple related domains and service providers, enhancing the company's market reach and operational capabilities.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a comprehensive cookie consent mechanism via Cookiebot. The use of Azure DNS and hosting suggests reliable infrastructure. However, the absence of visible security headers such as Content-Security-Policy, X-Frame-Options, and explicit security policies limits the overall security posture. No exposed sensitive data or vulnerable libraries were detected in the provided content. The lack of published incident response contacts and vulnerability disclosure policies indicates potential gaps in security governance and incident management readiness. Compliance with GDPR is partially evidenced by cookie consent but lacks full transparency due to missing privacy policy documentation. Overall, the security culture appears cautious but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data processing and user rights to improve GDPR compliance.
  2. Add a terms of service page to clarify user agreements and legal protections.
  3. Implement and publish a security policy including incident response contacts to enhance transparency and readiness.
  4. Deploy additional security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen technical defenses.
  5. Provide clear company contact information including emails and phone numbers to improve user trust and business credibility.

Technical notes

Notes

The website is built on a modern technology stack including JavaScript and CSS, hosted on Microsoft Azure infrastructure with Azure DNS. Cookiebot is integrated for cookie consent management, indicating attention to privacy compliance. The site is mobile optimized and includes appropriate meta tags for SEO. Performance is moderate with no evident broken elements. However, no CMS or specific web frameworks were detected from the provided content. The hosting environment is professional and reliable. Opportunities exist to improve accessibility features and implement advanced security headers. Technical risks are minimal but include potential compliance gaps due to missing privacy and security documentation.
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.
