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. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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.

Dark web exposure

Add-on

Leaked records that mention schulbau-messe.de, from OffSeq Breach.

No leaked records found

Breach holds no records for schulbau-messe.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates in the education and media sectors, leveraging content publishing and event organization as primary revenue streams. Its target audience includes architects, school authorities, and educational planners, indicating a B2B focus. The company maintains partnerships with event platforms and media outlets, enhancing its market reach. The business model includes subscription services and advertising, supported by a clear brand presence and consistent content quality. Growth indicators include active event scheduling and multilingual content, suggesting expansion ambitions.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent implemented via Complianz GDPR plugin. However, the absence of DNSSEC and explicit security headers like CSP and X-Frame-Options indicates room for enhancement. No incident response or vulnerability disclosure information is publicly available, which could be a gap in transparency. No exposed sensitive data or vulnerable libraries were detected. Overall, the security risk is moderate with recommendations to strengthen DNS and header configurations and publish security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party plugins and scripts to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern WordPress 6.8.2 platform with a well-integrated tech stack including WooCommerce for e-commerce, The Events Calendar for event management, and Rank Math for SEO optimization. The site is hosted with Cronon GmbH, a reputable provider. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. The site uses Google Tag Manager and Analytics for tracking, balanced with GDPR-compliant cookie consent. Technical risks are low but could be further mitigated by improving security headers and DNS configurations.
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.
