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

Talleux & Zöllner GbR is a small German web agency specializing in TYPO3 CMS based website and web application development. They serve medium-sized companies, organizations, and agencies, offering services including conception, programming, maintenance, and support. The website reflects a professional and consistent brand with clear presentation of team members and certifications, indicating a trusted niche player in the TYPO3 ecosystem. Technically, the site is built on TYPO3 CMS with PHP, Python, and JavaScript technologies, showing moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and explicit security policies. Privacy compliance is partially met with a privacy policy present but no cookie consent mechanism. Overall, the site is trustworthy and professionally maintained, though improvements in security and privacy transparency are recommended.

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

7 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 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';…

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 targets medium-sized enterprises, organizations, and agencies needing web development services, particularly TYPO3 CMS solutions. Their business model focuses on project-based development with ongoing maintenance and support, leveraging certified TYPO3 developers as a competitive advantage. Partnerships with design and communication agencies enhance their service offering. The absence of social media and analytics suggests a focus on direct client relationships rather than broad marketing. The company operates in the German market with a small team and a clear niche in TYPO3 CMS development.

Security posture

The website employs HTTPS and avoids exposing sensitive data in its HTML content. However, it lacks common security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. No incident response or security policy pages are published, indicating limited transparency in security governance. No vulnerability disclosures or security.txt files are present. The absence of cookie consent mechanisms may pose GDPR compliance risks. Overall, the security posture is moderate but could be enhanced with better headers, explicit policies, and privacy controls.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to improve web security.
  2. Add a cookie consent banner to comply fully with GDPR requirements.
  3. Publish a dedicated security policy and incident response contact information to increase transparency and trust.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Consider integrating analytics with privacy-respecting configurations to gain user insights while maintaining compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system, using PHP, Python, and JavaScript for web applications. The front-end includes jQuery and Slick Slider for responsive UI components. The site is mobile-optimized with responsive design and uses compressed CSS and JS assets for performance. SEO is supported by meta tags and structured navigation. No major technical debt or outdated technologies are evident. Hosting details are not explicit, but the domain uses standard nameservers. Performance is moderate, with potential for improvement by optimizing assets and caching strategies.
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.
