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

Mesonic Datenverarbeitung Gesellschaft m.b.H. is a well-established software company specializing in business software solutions such as ERP, CRM, and PPS targeted at small and medium-sized enterprises primarily in Austria and Germany. Their flagship product, WinLine, is widely used and supported by a network of certified partners providing installation, training, and support services. The website demonstrates a professional digital presence with comprehensive content, clear navigation, and multilingual support (German and English). The company emphasizes customer support, partner collaboration, and continuous education through its mesonic Academy. Technically, the website uses modern frameworks like Bootstrap and FontAwesome, ensuring a responsive and visually appealing user experience. Security-wise, the site enforces HTTPS and includes cookie consent mechanisms, though it lacks explicit security headers and incident response information. The absence of WHOIS data for the domain suggests it may be a subdomain or protected by privacy services, but the overall business credibility remains high based on website content and contact transparency.

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

6 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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"

    • 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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.

Business context

Business profile

Mesonic operates in the manufacturing and retail sectors, providing essential business software solutions that streamline operations for SMEs. Their business model leverages a partner network for distribution and support, enhancing market reach and customer service quality. The company maintains a strong brand presence with certifications like euBP, reinforcing trustworthiness. Their target customers are SMEs seeking integrated ERP and CRM solutions with scalability. The website content and partner listings indicate a mature ecosystem with strategic collaborations. Growth opportunities lie in expanding digital services and enhancing security and compliance transparency. Mesonic's market position is solid, supported by thousands of users and a comprehensive product suite.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and a cookie consent banner indicating GDPR awareness. However, the lack of visible security headers (e.g., CSP, HSTS) and absence of a dedicated security policy or incident response contact reduces the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The company should consider implementing additional security headers, publishing a security policy, and providing clear incident response channels to improve trust and compliance. Regular audits of third-party libraries and enhanced accessibility features would further strengthen security and usability.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Provide explicit contact information for security incidents (e.g., security@ or abuse@ email addresses).
  4. Conduct regular vulnerability assessments and update third-party libraries to mitigate risks.
  5. Enhance website accessibility to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is built using modern web technologies including Bootstrap 5 for responsive design, FontAwesome 6 for icons, and custom JavaScript for interactive elements such as dropdown menus and cookie consent management. The site is mobile-optimized with good navigation clarity and professional design quality. Performance is moderate, with no major issues detected in the HTML structure or resource loading. SEO practices are evident through proper meta tags and structured navigation. However, no CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Opportunities exist to improve accessibility and implement advanced security headers to reduce technical debt and enhance resilience.
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.
