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

IG Bauen-Agrar-Umwelt (IG BAU) is a well-established German trade union representing workers in construction, agriculture, environment, and cleaning sectors. The website serves as an information and membership portal, providing news, advocacy information, and digital services such as a member app. The organization maintains a strong social media presence and regularly updates content relevant to its members. Technically, the site uses a modern CMS (Additor), standard JavaScript libraries, and enforces HTTPS with cookie consent mechanisms, reflecting a moderate to good digital maturity. Security posture is adequate with SSL and consent-based analytics, but lacks explicit security policies and headers. Overall, the site is professional, trustworthy, and compliant with GDPR privacy requirements.

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. 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

  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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

IG BAU operates as a large essential entity within the trade union sector in Germany, focusing on labor rights and member services in specific industries. Its business model centers on membership and advocacy rather than commercial sales. The union's market position is strong nationally, supported by active communication channels and sector-specific news. The organization leverages partnerships via social media but does not publicly disclose subsidiaries or parent companies. The website content and structure support clear navigation and engagement with its target audience of workers and union members.

Security posture

The website demonstrates a baseline security posture with enforced HTTPS, cookie consent, and use of privacy-respecting analytics (Matomo). However, it lacks visible security headers such as Content-Security-Policy and does not publish a security policy or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a vulnerability disclosure program or security.txt file indicates room for improvement in transparency and incident readiness. Overall, the security maturity is moderate but could be enhanced with formal policies and technical headers.

Recommendations

  1. Publish a clear security policy and incident response information on the website.
  2. Implement and serve security headers like Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  3. Add a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Provide direct contact information such as security or abuse email addresses for incident reporting.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and trust.

Technical notes

Notes

The website is built on the Additor CMS platform, utilizing jQuery, Bootstrap components, and Klaro for cookie consent management. Hosting is provided by Colt, a reputable provider, as indicated by the nameservers. Performance is moderate with lazy loading images and deferred scripts improving load times. SEO is supported by canonical tags, meta descriptions, and Open Graph metadata. Mobile optimization is good with responsive design elements. However, accessibility is basic and could be improved. No major technical debts or outdated libraries were detected, but security headers are missing which is a technical risk.
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.
