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

C3 marketing agentur GmbH is a German marketing and advertising agency with offices in Tirschenreuth and Regensburg. The company offers a broad range of services including website development, e-commerce solutions, print and graphic design, photography, video, 3D media, and advertising campaigns. Their market position appears well-established with over two decades of presence and a strong regional footprint. The website is professionally designed, mobile-optimized, and provides clear navigation and comprehensive content in German, targeting businesses seeking marketing services in Germany. Technically, the website is built on TYPO3 CMS, leveraging modern web technologies such as SVG graphics and JavaScript modules. Accessibility features and cookie consent mechanisms are implemented, reflecting a mature digital infrastructure. Performance is moderate with good mobile optimization and SEO practices. From a security perspective, the site uses HTTPS and implements cookie consent but lacks visible security headers and published security or incident response policies. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS domain registration data is a notable concern, potentially indicating privacy protection or an unregistered domain, which slightly reduces trustworthiness. Overall, the website presents a professional and trustworthy front for a marketing agency, but domain registration transparency and enhanced security disclosures would improve credibility and compliance posture.

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

5 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 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 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

C3 marketing agentur GmbH operates in the media sector as a full-service marketing agency. Their business model focuses on providing creative and strategic marketing solutions to regional clients in Germany. The company leverages a mix of traditional and digital marketing tools, including e-commerce and immersive media. Their competitive advantage lies in their comprehensive service offering and long-standing market presence. The agency maintains active social media channels and showcases client logos, indicating a healthy partnership ecosystem. Growth indicators include participation in industry events and continuous content updates. The company targets businesses requiring marketing expertise, positioning itself as a trusted regional partner.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism aligned with GDPR requirements. However, the lack of security headers such as Content-Security-Policy and absence of published security or incident response policies indicate gaps in security best practices. No vulnerabilities or sensitive data exposures were found in the analysis. The missing WHOIS data raises questions about domain legitimacy, which could impact trust. Compliance with GDPR is evident through privacy and cookie policies, but incident response readiness and security culture indicators are not publicly visible. Overall, the security posture is adequate but could be strengthened with additional transparency and technical controls.

Recommendations

  1. Implement and publish security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Establish and disclose an incident response policy and contact channels for security issues.
  3. Verify and update WHOIS domain registration information to improve domain legitimacy and trust.
  4. Enhance transparency by publishing a security policy and data protection officer contact details.
  5. Regularly audit and update third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system. It uses modern web standards including HTML5, CSS3, SVG graphics, and JavaScript modules for interactivity and accessibility features. The site includes a cookie consent framework with granular control over cookie categories. Performance is moderate with good mobile responsiveness and SEO optimization. No critical technical debt or deprecated technologies were detected. Opportunities exist to improve security headers and implement a security.txt file for vulnerability disclosure. Hosting provider details were not identified from the content.
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.
