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

  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';…

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

The company positions itself as a regional specialist IT service provider focusing on public sector and SME clients. Their business model revolves around IT consulting and managed services with a strong emphasis on virtualization and security solutions. The company leverages partnerships for telecommunications and security implementations. The website content is relevant but basic, indicating a traditional approach to digital presence. The absence of modern marketing and analytics tools suggests limited digital marketing efforts. The company appears stable with a long history since 2002 but lacks visible certifications or advanced trust signals.

Security posture

The security posture is weak due to the absence of HTTPS enforcement, lack of security headers, and use of deprecated Flash content. No incident response or security policy information is provided. Remote support tools are linked but no details on secure usage are available. The site does not demonstrate GDPR compliance beyond having a privacy policy page. Overall, the security maturity is low, exposing the company and its clients to potential risks.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Remove all deprecated Flash content and update the website to modern HTML5 standards.
  3. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and HSTS.
  4. Introduce a cookie consent mechanism to comply with GDPR and improve privacy compliance.
  5. Publish a clear security policy and incident response contact information to enhance trust.

Technical notes

Notes

The website is built on static HTML with embedded JavaScript and CSS, lacking modern CMS or frameworks. It uses outdated Flash for logo animation, which is unsupported by most modern browsers. The hosting is via rzone.de, a German hosting provider, consistent with the regional focus. Performance is moderate but mobile optimization and accessibility are poor, limiting user experience on mobile devices and for users with disabilities. SEO is basic with meta tags present but no structured data or Open Graph tags. No analytics or tracking scripts are detected, indicating minimal data collection.
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.
