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

7 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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

meravis holds a strong regional market position in the German real estate sector, targeting tenants, buyers, investors, and job seekers. The business model revolves around property rental, sales, and development, supported by digital services like the meine.meravis portal. The company leverages social media and digital marketing tools to engage customers and maintain brand visibility. The website content and structure support clear navigation and service discovery, indicating a customer-centric approach. No parent or subsidiary companies were identified, suggesting an independent medium-sized enterprise with a focused market niche.

Security posture

The website demonstrates a good security baseline with HTTPS and consent management via Usercentrics. No exposed sensitive data or vulnerable libraries were found. However, the absence of explicit security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and preparedness. The use of third-party analytics and marketing scripts is managed with user consent, aligning with GDPR. Security headers are not explicitly detected, which could be enhanced to mitigate common web threats. Overall, the security posture is adequate but could benefit from formalized policies and technical hardening.

Recommendations

  1. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and trust.
  3. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly review and update third-party scripts and consent management configurations to maintain privacy compliance and reduce risk.

Technical notes

Notes

The website is built on TYPO3 CMS, utilizing Bootstrap for responsive design and jQuery-based plugins for UI components like sliders, menus, and date pickers. It integrates Usercentrics for consent management and etracker and HubSpot for analytics and marketing automation. The site loads scripts asynchronously to optimize performance, though some improvements in caching and security headers could be made. Mobile optimization is good, with responsive menus and layouts. SEO is supported by meta tags and structured navigation. The technical stack is modern and well-maintained, suitable for a medium-sized real estate business.
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.
