Risk levelHigh

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

Brain Appeal GmbH is a specialized internet agency based in Mannheim, Germany, focusing on TYPO3 CMS and Symfony-based web development and consulting since 1998. The company offers tailored TYPO3 solutions including consulting, relaunches, extension development, and proprietary digital products such as time tracking and event calendar systems, primarily serving educational institutions and businesses. Their website is professionally designed, multilingual, and showcases recent projects and certifications, reflecting a mature and credible digital presence. Technically, the site uses TYPO3 CMS, Symfony, and Matomo analytics with privacy-conscious configurations. Security posture is good with HTTPS and cookie tracking disabled, though security headers and cookie consent mechanisms could be improved. WHOIS data is missing or unavailable, which raises some concerns about domain registration legitimacy, but the overall business credibility and website professionalism mitigate this risk. Strategic recommendations include enhancing security headers, implementing cookie consent, and clarifying domain registration details.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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

  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 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. GDPR outside view

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

    • 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

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 · found on this site
  • 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

Business profile

Brain Appeal GmbH occupies a niche market as a TYPO3 specialist agency with a strong focus on education sector clients and digital product offerings. Their competitive advantage lies in certified expertise, long-standing experience since 1998, and a comprehensive service portfolio including consulting, development, and proprietary solutions. The business model is service-oriented with additional revenue from digital products. The company maintains active social media channels and demonstrates a consistent brand identity. Growth indicators include recent project showcases and active blogging. Partnerships with TYPO3 and educational institutions reinforce their market position. The absence of WHOIS data is a notable anomaly requiring further investigation but does not currently undermine operational credibility.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and privacy-conscious analytics configuration (Matomo with cookies disabled). However, the absence of key security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the overall security posture. No visible vulnerability disclosures or incident response contacts are published, which limits transparency in security management. The lack of a cookie consent mechanism is a GDPR compliance gap. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is solid but could be enhanced by implementing recommended headers, formalizing incident response information, and adding cookie consent.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and inform users about tracking and cookies.
  3. Publish a security.txt file or vulnerability disclosure policy to improve transparency and incident response readiness.
  4. Clarify domain registration status and WHOIS information to remove legitimacy concerns and improve trust.
  5. Regularly audit and update third-party libraries and extensions to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS with Symfony framework components, leveraging modern web technologies including HTML5, CSS3, and JavaScript. It uses Matomo for privacy-focused analytics with cookies disabled, indicating a strong privacy stance. The site is multilingual with hreflang tags for SEO and accessibility. Performance is moderate with video backgrounds and rich media content, balanced by compressed CSS and JS assets. Mobile optimization and accessibility features are good, with ARIA landmarks and responsive design. No major technical debt or errors were detected in the HTML content. Hosting provider details are not disclosed. Opportunities exist to improve security headers and cookie consent mechanisms to align with best practices.
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.
