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

4 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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Goldbach holds a strong market position as a key advertising sales entity in the DACH region, targeting advertisers and agencies seeking multi-channel advertising solutions. Their business model centers on media sales and campaign services, supported by partnerships such as Splicky for programmatic advertising. The company demonstrates growth through diverse media offerings and seasonal promotional deals. The website content and structure indicate a focus on customer education and service transparency, with case studies and success stories enhancing credibility. The absence of explicit company registration or VAT details on the site is a minor gap in business transparency.

Security posture

The website employs HTTPS with valid SSL and domain status protections to prevent unauthorized changes. However, DNSSEC is not enabled, which is a recommended security enhancement. No explicit security headers were detected in the provided data, suggesting potential improvements in HTTP security configurations. The site uses reputable third-party scripts for analytics and advertising, which are standard in the industry but require ongoing monitoring for vulnerabilities. There is no public security policy or incident response information, which could be added to improve transparency and readiness. No vulnerabilities or exposed sensitive data were identified in the analysis.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement and configure security headers such as Content Security Policy (CSP), HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  4. Add a security.txt file and vulnerability disclosure policy to facilitate responsible reporting.
  5. Provide explicit contact information including company emails and phone numbers to improve trust and compliance.

Technical notes

Notes

The website is built using Nuxt.js, a modern Vue.js framework supporting server-side rendering, which improves SEO and performance. It integrates multiple third-party services including Google Tag Manager, Adform for advertising and tracking, and Dialogify for chat functionality. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile-optimized and uses lazy loading for images and scripts to enhance performance. Some scripts are loaded asynchronously to reduce blocking. Overall, the technical infrastructure is modern and robust, though performance is moderate and could benefit from further optimization and accessibility improvements.
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.
