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

OTTO MAURER Assekuranzmakler GmbH is a specialized insurance brokerage firm focusing on inland navigation, construction, recycling, and related industries primarily in Germany and the BeNeLux region. With over 30 years of experience and affiliation to the HÜLSKENS-Firmenverband group, the company offers tailored insurance solutions including Flusskasko, P&I, machinery breakdown, and freight loss insurance. The website reflects a professional and consistent brand presence with clear service descriptions and multiple contact points. Technically, the website is built on the Contao Open Source CMS platform, utilizing common JavaScript libraries such as jQuery and Swipe.js for UI components. The site is moderately performant, mobile-optimized, and SEO-friendly, though accessibility features are basic. Hosting appears to be managed via Agenturserver, with no direct evidence of advanced security headers or analytics tools. From a security perspective, the site uses HTTPS and implements a cookie consent mechanism compliant with GDPR. However, no explicit security policy or incident response contacts are published, and security headers are not evident. No vulnerabilities or suspicious content were detected. The WHOIS data aligns well with the business claims, showing consistent registration and no privacy protection, supporting legitimacy. Overall, the website is trustworthy, professional, and compliant with privacy regulations, though improvements in security policy transparency and technical security headers are recommended to enhance the security posture and trust further.

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

8 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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"

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 · found on this site
  • 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

The company holds a strong market position as a niche insurance broker specializing in sectors with complex risk profiles such as inland shipping and construction. Their business model leverages deep industry knowledge to provide customized insurance products. The affiliation with the HÜLSKENS-Firmenverband group and subsidiaries ECONOMIC and JUWE Assekuranzmakler GmbH suggests a collaborative ecosystem enhancing service offerings. The target customers are primarily medium-sized enterprises in transportation, manufacturing, and recycling sectors. The website content and structure indicate a mature business with stable operations and a focus on client trust and service quality.

Security posture

The current security maturity level is moderate. The site benefits from HTTPS and GDPR-compliant cookie consent but lacks visible advanced security headers and a published security policy or incident response contacts. No exposed sensitive data or vulnerable libraries were detected. The absence of security.txt or vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Overall, the security posture is adequate for the business type but could be enhanced by adopting best practices in security headers, incident response communication, and regular security audits.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and incident response procedures.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a security.txt file to facilitate vulnerability reporting and improve transparency.
  4. Regularly update and audit third-party libraries and CMS components to mitigate vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on the Contao CMS platform, leveraging jQuery, jQuery UI, Colorbox, and Swipe.js for interactive elements. The site uses responsive design techniques and includes a cookie consent mechanism. Hosting is managed via Agenturserver, indicated by the nameservers. Performance is moderate with no critical technical debt observed. SEO is supported by proper meta tags and structured data in JSON-LD format. Accessibility is basic but could be improved. No advanced analytics or tracking scripts were detected, indicating a privacy-conscious approach. Overall, the technical infrastructure is stable and suitable for the business needs.
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.
