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

TYPO3.org represents the TYPO3 Association and its flagship open source enterprise CMS product, TYPO3 CMS. The website serves a global community of developers, enterprises, and content professionals, providing extensive documentation, community engagement, and security advisories. The business model is community-driven and supported by membership fees, donations, and events. Technically, the site uses TYPO3 CMS with PHP and JavaScript, integrating analytics and SEO tools. However, the lack of a valid SSL certificate and modern TLS protocols is a significant security concern. The site demonstrates good GDPR compliance and cookie consent mechanisms, with active security advisory publication and community transparency. Overall, TYPO3.org is a professional and trustworthy platform with room for critical security improvements.

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. 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';…

  2. 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
  • 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

TYPO3 Association holds a strong position in the open source CMS market, targeting enterprise users and developers. Its competitive advantage lies in its scalability, professional ecosystem, and active community. Revenue streams include membership fees, donations, and certification services. The partnership with typo3.com enhances its certification and professional service offerings. The association's global reach and community events indicate growth and engagement. Strategic observations include the need to modernize security infrastructure and enhance incident response visibility to maintain trust and compliance.

Security posture

The current security posture shows moderate maturity with strong policy frameworks like SPF and DMARC in place. However, the absence of a valid SSL certificate and disabled TLS protocols expose the site to risks such as data interception and reduced user trust. The site lacks HSTS, OCSP stapling, and session resumption, which are best practices for HTTPS security. Incident response contact details are not explicitly provided, and no security.txt file is found. GDPR compliance is well addressed through privacy and cookie policies. The security culture is community-oriented but needs technical hardening to mitigate vulnerabilities.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate supporting TLS 1.2 or 1.3 to secure all web traffic.
  2. Enable HSTS with includeSubDomains and preload to enforce HTTPS and prevent downgrade attacks.
  3. Correct and define valid CAA DNS records to restrict certificate issuance.
  4. Implement OCSP stapling and session resumption to improve TLS performance and security.
  5. Publish a security.txt file and provide clear incident response contact information to enhance vulnerability disclosure and response.
  6. Regularly audit and update security headers and configurations to align with best practices and compliance requirements.
Technical notes

Notes

The TYPO3.org website is built on TYPO3 CMS, leveraging PHP and JavaScript, with integrations for Google Analytics, Google Tag Manager, and Piwik/Matomo for analytics. SEO is enhanced using Yoast SEO for TYPO3. The site performance is moderate with a page load time of approximately 6 seconds and a page size of 350 KB. Mobile optimization and accessibility are good, with responsive images and ARIA roles. Hosting is via IP 185.17.71.137 with opsdns nameservers. Technical debt is indicated by the lack of valid SSL and outdated TLS support. Modernization opportunities include upgrading TLS, improving DNS CAA records, and enhancing security headers. These improvements will reduce technical risks and improve user trust and compliance.
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.
