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. 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 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';…

  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
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 operates in the media sector, providing integrated marketing and digital services. Their competitive advantage lies in their long-standing expertise with TYPO3 CMS, own hosting capabilities, and a broad service offering from creative design to digital transformation including AI and data analytics. Their business model is service-oriented, focusing on B2B clients in need of customized digital and print media solutions. The presence of multiple social media channels and partnerships with recognized organizations enhances their market credibility. The company targets medium-sized businesses and organizations primarily in Germany, with growth potential in digital business and AI-driven services. Their strategic partnerships and certifications support a sustainable and reputable market presence.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a well-defined Content-Security-Policy restricting resource origins. No critical vulnerabilities or exposed sensitive data were detected. However, additional security headers such as HSTS, X-Frame-Options, and Referrer-Policy could further strengthen defenses. The use of third-party scripts is controlled but should be regularly audited. Privacy compliance is robust with explicit cookie consent and detailed policies. Incident response and security policy information are not publicly disclosed, which could be improved to enhance transparency and readiness. Overall, the security measures align well with industry best practices for a media agency website.

Recommendations

  1. Implement additional security headers including HSTS, X-Frame-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit third-party scripts and tracking tools to mitigate potential vulnerabilities.
  4. Maintain and update cookie consent mechanisms to comply with evolving privacy regulations.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and flexible content management system, supported by custom JavaScript and CSS assets. It uses modern web standards and includes responsive design for mobile optimization. Hosting is managed internally in a Regensburg datacenter, which supports data security and performance. Analytics are implemented via Matomo and Google Analytics, with marketing tools like Facebook Pixel and Google Tag Manager integrated. The site loads with moderate speed and has good SEO optimization including meta tags and structured navigation. Accessibility is addressed with a focus on barrier-free web design. Technical debt appears low, but continuous monitoring and updates are recommended to maintain security and performance.
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.
