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

Vonovia SE is a leading real estate company based in Germany, specializing in property management and housing services. The analyzed page 'Hand aufs Werk' is part of their career section, targeting individuals interested in hands-on roles within the company. The website demonstrates a professional and consistent brand presence with a focus on user experience and compliance with cookie consent regulations. Technically, the site uses modern web technologies including JavaScript frameworks and Cookiebot for privacy management. Analytics tools such as Econda and Google services are employed to monitor user interactions. Security posture is moderate with cookie consent implemented but lacks visible security headers and incident response contacts. WHOIS data is missing or inaccessible, which raises some concerns about domain registration transparency but does not detract from the apparent legitimacy of the business. Overall, the website is well-structured, secure, and compliant with privacy norms, serving a large enterprise audience in the real estate sector.

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. 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

  • 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

Vonovia SE operates in the real estate sector with a strong market position in Germany. Their business model focuses on property management and housing services, supported by a comprehensive digital presence including multiple related domains. The company targets job seekers and potential employees, emphasizing career opportunities. The use of advanced analytics and marketing tools indicates a mature digital marketing strategy. Partnerships with entities like Deutsche Wohnen and subsidiaries under the Vonovia brand enhance their market reach. The absence of direct contact information on the analyzed page suggests a focus on digital self-service and centralized contact points elsewhere on the site. The company appears to maintain a strong compliance posture with GDPR and cookie regulations, reflecting a commitment to data privacy and user trust.

Security posture

The website shows a moderate security maturity level with the implementation of a detailed cookie consent mechanism via Cookiebot, categorizing cookies into necessary, preferences, statistics, and marketing. However, the lack of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options is a gap. No incident response or security contact information is provided, which could hinder timely reporting and handling of security issues. The absence of WHOIS data raises questions about domain registration transparency but does not necessarily indicate malicious intent. Overall, the site follows basic security best practices but would benefit from enhanced header configurations and clearer security policies to improve trust and compliance.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish clear and accessible privacy policy and terms of service pages linked from all relevant pages.
  3. Provide explicit security incident response contact information to facilitate vulnerability reporting.
  4. Investigate and resolve the missing WHOIS data to improve domain registration transparency.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and trust.

Technical notes

Notes

The website uses modern JavaScript frameworks, likely Angular or a similar SPA framework, with custom elements and hydrated classes. Cookiebot is integrated for cookie consent management, and analytics tools such as Econda and Google Analytics are used for traffic analysis. The site appears mobile-optimized with good SEO practices including meta tags and Open Graph data. Performance is moderate, with asynchronous loading of scripts and deferred execution. No CMS or hosting provider details are explicitly found. The technical stack supports a professional and scalable web presence but could improve in accessibility and security header implementation.
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.
