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

5 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. 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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention sinfonima.de, from OffSeq Breach.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Mannheimer Versicherung AG targets a specialized market segment within the insurance industry, focusing on classical music professionals and organizations. This niche positioning provides competitive advantage by addressing unique insurance needs not commonly covered by general insurers. The business model likely includes direct insurance sales and partnerships with music industry stakeholders. The website supports this with content aimed at educating and engaging musicians and related entities. The presence of online calculators and contact forms indicates a customer-centric approach. The company maintains a moderate size and operates primarily in Germany. The partnership ecosystem includes related domains under the mannheimer.de umbrella, reinforcing brand consistency and service integration.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, Content-Security-Policy headers, and cookie consent mechanisms. No critical vulnerabilities or security misconfigurations were detected in the HTML content. However, the absence of a published security policy, vulnerability disclosure program, or incident response contact information represents a gap in transparency and readiness. The site uses reputable third-party services for analytics and consent management, which are integrated securely. Overall, the security measures are appropriate for the business type but could be enhanced by publishing formal security and incident response documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Enhance website accessibility to meet higher standards for users with disabilities.
  5. Add a terms of service page to clarify user agreements and legal conditions.

Technical notes

Notes

The website is built on a robust and modern technology stack centered around Liferay DXP, React, and Clay UI, ensuring modularity and maintainability. The use of jQuery and various UI libraries like Photoswipe and Slick Carousel enhances user experience with interactive elements. Cookie consent and analytics are managed via Usercentrics and Piwik PRO respectively, reflecting compliance and data-driven insights. Hosting via Ecotel with dedicated nameservers indicates a professional hosting environment. Performance is moderate with combined and minified resources, though further optimization could improve load times. SEO and mobile responsiveness are well addressed, but accessibility features are basic and could be improved to broaden audience reach and compliance.
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.
