Security score

Risk levelMedium

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

The C4C group website presents a professional business offering strategic consulting, creative communication solutions, and custom web development services primarily targeting large companies, public institutions, and medium-sized enterprises in Germany. The site is built on TYPO3 CMS and integrates Cookiebot for GDPR-compliant cookie consent management. The technical infrastructure is modern and mobile-optimized, with good SEO and accessibility features. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks explicit security headers and publicly available security policies or incident response contacts. The WHOIS data is missing or unavailable, which raises some concerns about domain registration legitimacy despite the professional website presence. Overall, the site is trustworthy and well-designed but would benefit from enhanced transparency and security disclosures.

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 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';…
  2. 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
  3. 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
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality

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

C4C group operates as a multi-disciplinary consulting and service provider uniting three subsidiaries focused on consulting, creative branding, and technological solutions. Their business model emphasizes integrated communication competence combining strategy, creativity, and technology to support digital transformation and process optimization. The company targets enterprise and institutional clients, positioning itself as a comprehensive partner with tailored solutions. The linked subsidiary domains reinforce a structured corporate ecosystem. No direct revenue or financial data is available, but the professional presentation and detailed service descriptions indicate a mature business with a clear market niche in Germany.

Security posture

The website enforces HTTPS and uses a reputable cookie consent management system (Cookiebot), indicating compliance with privacy regulations. However, the absence of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security posture. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are publicly available, which limits transparency and preparedness for security incidents. The missing WHOIS data is a notable anomaly that could affect trust. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security maturity is moderate but could be improved with better header implementation and public security documentation.

Recommendations

  1. Implement and publish comprehensive security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  2. Provide explicit security and incident response policies on the website, including contact channels for reporting security issues.
  3. Publish a terms of service page to clarify legal usage and liability, improving business credibility.
  4. Add clear company contact information including emails and phone numbers to improve transparency and user trust.
  5. Investigate and resolve the missing WHOIS data issue to ensure domain registration legitimacy and improve trustworthiness.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, and uses modern web technologies including SVG graphics and JavaScript. Cookiebot is integrated for cookie consent management, supporting GDPR compliance. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with no major issues detected in the HTML structure or meta tags. The absence of explicit hosting provider information limits full infrastructure assessment. Overall, the technical implementation is solid with opportunities to enhance security headers and improve contact data visibility.
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.
