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

GMG GmbH is a medium-sized IT and media service provider operating primarily in Switzerland and Liechtenstein. Founded in 1991, the company offers a broad range of services including IT systems engineering, web development, media project management, and hardware sales and repair. They maintain data centers in Balzers and Zurich, supporting a regional customer base with SaaS contracts and 24/7 support. The website reflects a professional and established business with detailed team and contact information, targeting business clients in the region. Technically, the website is built on ASP.NET Web Forms, uses jQuery and fullPage.js for UI, and integrates Matomo for analytics, indicating a moderate level of digital maturity. The site is served over HTTPS with a custom CMS and hosted likely on Windows IIS servers. Mobile optimization and accessibility are basic but functional. No major performance issues were detected. From a security perspective, the site enforces HTTPS and uses secure form validation but lacks important security headers such as Content-Security-Policy and X-Frame-Options. No exposed sensitive data or vulnerable libraries were found. Privacy compliance is partial; a privacy policy is present but no cookie consent mechanism is implemented. WHOIS data is unavailable, which slightly reduces trust but the website content and contact details support legitimacy. Overall, GMG GmbH presents a trustworthy and professional online presence with room for improvement in security headers and privacy compliance. Strategic enhancements in these areas would strengthen their security posture and regulatory adherence.

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. 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 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';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

GMG GmbH holds a strong regional position as a comprehensive IT and media service provider with over 30 years of operational history. Their business model focuses on integrated service delivery combining consulting, software development, hardware sales, and support services. Revenue streams likely include SaaS contracts, project-based web and media development, and hardware sales/repair. The company targets SMEs and enterprises in Switzerland and Liechtenstein, leveraging local data centers for hosting and support. The detailed team presentation and multiple office locations indicate stable operations and a mature organizational structure. Absence of social media presence suggests a focus on direct client relationships and regional reputation. The use of Matomo analytics aligns with privacy-conscious business practices. No evident partnerships or subsidiaries were identified from the website content.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and ASP.NET form validation is used to protect input handling. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose the site to clickjacking, MIME sniffing, and other attacks. No signs of exposed credentials or vulnerable third-party libraries were found. Privacy compliance is partial; while a privacy policy exists and Matomo analytics is used (which is privacy-friendly), the lack of a cookie consent mechanism is a compliance risk under GDPR. Incident response and security policy information are not published, limiting transparency. WHOIS data is missing, which may indicate privacy protection but reduces domain trust. Overall, the security posture is adequate for a regional business but could be improved with enhanced headers, cookie consent, and published security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie consent banner/mechanism to comply with GDPR and enhance user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and readiness.
  4. Regularly audit and update all third-party libraries and frameworks to avoid vulnerabilities.
  5. Consider enhancing mobile responsiveness and accessibility to improve user experience across devices.

Technical notes

Notes

The website is built on a mature ASP.NET Web Forms platform with client-side enhancements using jQuery and fullPage.js for smooth navigation and UI effects. It uses a custom CMS allowing clients to manage content. Hosting appears to be on IIS servers with HTTPS enabled. The site loads external fonts from fast.fonts.net and uses Matomo for analytics, indicating a preference for privacy-friendly tools. Performance is moderate with no evident blocking scripts or heavy resources. Mobile optimization is basic but functional. Accessibility features are minimal but present. The site uses standard ASP.NET hidden fields for state management and event validation, indicating a traditional but stable technical stack. Opportunities exist to modernize the tech stack and improve SEO and accessibility 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.
