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

netzwerker Computernetze GmbH is a German IT service provider specializing in network infrastructure, cybersecurity, cloud, and internet services primarily serving the Stuttgart and Hamburg metropolitan regions. The company positions itself as a trusted IT partner with over 20 years of experience, focusing on comprehensive IT solutions and system support. The website reflects a professional and business-oriented approach with clear service offerings and regional targeting. Technically, the website is built on the Contao Open Source CMS platform, utilizing jQuery and jQuery UI libraries. The site is moderately optimized for mobile devices and offers a good user experience with clear navigation. However, there is room for improvement in SEO and accessibility features. No advanced frameworks or platforms beyond the CMS and JavaScript libraries were detected. From a security perspective, the site uses HTTPS (implied by base href https://), but no explicit security headers were detected in the provided data. There is no visible cookie consent mechanism or detailed security policy, which may impact GDPR compliance. No forms or data collection points were found on the homepage, reducing immediate risk exposure. The WHOIS data is minimal but consistent with the domain's purpose, though domain age and registrant details are limited. Overall, the website is safe, professional, and trustworthy but could benefit from enhanced security practices, privacy compliance improvements, and more transparent contact information to strengthen business credibility and user trust.

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

    • 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 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
  • 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

netzwerker Computernetze GmbH operates as a specialized IT system house and service provider in Germany, focusing on network infrastructure and cybersecurity solutions. Their business model revolves around providing comprehensive IT services to regional enterprises, emphasizing personalized and competent service. The company leverages its long-standing market presence and regional focus as competitive advantages. Revenue streams likely include managed IT services, cloud solutions, and cybersecurity consulting. The target customers are businesses in Stuttgart and Hamburg metropolitan areas seeking reliable IT partners. The website content and structure suggest a stable, small-sized company with a clear service portfolio but limited digital marketing or e-commerce capabilities. No evident partnerships or subsidiaries were identified from the data.

Security posture

The current security posture is basic with HTTPS usage but lacks visible security headers and formalized security policies on the website. No incident response or vulnerability disclosure information is provided, indicating limited transparency in security governance. The absence of cookie consent mechanisms and detailed privacy notices may pose compliance risks under GDPR. No known vulnerabilities or exposed sensitive data were detected in the content. The security maturity appears low to moderate, suitable for a small IT service provider but requiring enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  2. Add a visible cookie policy and consent mechanism to ensure GDPR compliance and user transparency.
  3. Publish detailed security and incident response policies, including vulnerability disclosure guidelines, to enhance trust and compliance.
  4. Include clear and accessible contact information such as company emails and phone numbers on the website to improve business credibility and user support.
  5. Conduct regular security audits of third-party libraries and scripts to identify and mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on Contao CMS with jQuery and jQuery UI libraries, indicating a moderately modern but not cutting-edge technology stack. The site loads with moderate performance and is mobile optimized to a good degree. SEO optimization is basic, with meta tags present but minimal description content. Accessibility features are limited but present. Hosting appears to be managed via ns2.nwhosts.com name servers, suggesting a standard hosting environment. There is no evidence of advanced frameworks or cloud platforms. The technical implementation is stable but could benefit from modernization and enhanced security configurations.
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.
