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

3 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 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 business positions itself as a specialized web consulting and social media service provider in the Köln region, focusing on personalized service and client satisfaction. The portfolio showcases multiple client projects across various sectors, indicating a diverse client base and a service-oriented business model. The company leverages partnerships with clients rather than subsidiaries or parent companies. The presence of testimonials and detailed client references enhances credibility. The business model relies on consulting, design, implementation, and ongoing social media support, with additional offerings like workshops. Growth indicators include recent portfolio updates and active client engagement.

Security posture

The website exhibits a mature security posture for a small business, with HTTPS enforced and a comprehensive cookie consent mechanism ensuring GDPR compliance. No exposed sensitive data or vulnerable libraries were identified in the HTML content. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not confirmed and should be implemented to enhance protection against common web attacks. Incident response and security policy documentation are absent, which is typical for small businesses but represents an area for improvement. Overall, the security risk is low, but proactive enhancements are recommended.

Recommendations

  1. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense-in-depth.
  2. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Maintain and update privacy and cookie policies to reflect any changes in data processing or third-party integrations.

Technical notes

Notes

The website is built using a modern frontend stack with Bootstrap for responsive design, jQuery for interactivity, and several UI libraries such as Owl Carousel and Magnific Popup. Cookiebot is integrated for cookie consent management, ensuring GDPR compliance. The site is hosted on DomainControl nameservers, indicating use of a common domain registrar hosting service. Performance is moderate with no evident blocking scripts or heavy resources. SEO is supported by appropriate meta tags and canonical links. Mobile optimization is good, and the site includes favicon and manifest files for better user experience. No CMS was detected, suggesting a custom or static site approach. Technical debt appears low, but security header implementation and accessibility improvements are opportunities for modernization.
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.
