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

6 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

    • 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

  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

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 as a small-sized service provider in the marketing and communication sector, targeting clients primarily in Germany across various industries including science, education, public sector, and culture. Their business model focuses on delivering tailored communication solutions combining creative design and technical implementation. The firm benefits from long-term client relationships and certifications such as RKW Thüringen accreditation, enhancing credibility. Their partnership ecosystem includes memberships in marketing associations, and they maintain active social media channels for outreach. Growth indicators include a diversified service portfolio and a strong digital footprint. Strategic observations suggest continued investment in digital innovation and compliance will support sustained market relevance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no exposed sensitive data. However, the absence of explicit security policies, incident response contacts, and security headers indicates room for improvement. No vulnerabilities or malicious scripts were detected in the provided content. GDPR compliance is evident through the privacy policy, but cookie consent mechanisms are not clearly implemented. The lack of a vulnerability disclosure or security.txt file suggests limited transparency in security incident handling. Overall, the security posture is adequate for a marketing agency but could be enhanced to meet higher standards and build greater trust.

Recommendations

  1. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) to strengthen defense against common web attacks.
  2. Add a dedicated security policy and incident response page including contact channels such as security@ or abuse@ emails.
  3. Introduce a cookie consent banner/mechanism to ensure full GDPR compliance and user transparency.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to improve security transparency.
  5. Regularly audit third-party libraries and scripts for vulnerabilities and update them promptly.

Technical notes

Notes

The website uses a modern technology stack including Contao CMS, jQuery, GSAP for animations, Lenis for smooth scrolling, and Three.js for advanced 3D graphics rendering. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by rich media content such as videos and 3D animations. SEO is well supported by meta tags, canonical URLs, and structured JSON-LD data enhancing search engine visibility. Hosting is managed via DomainControl nameservers, a reputable provider. Technical risks are minimal but could be mitigated further by enhancing security headers and monitoring third-party dependencies.
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.
