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

2 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 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

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 business operates in the media and hospitality sectors, focusing on event management and community engagement. Its competitive advantage lies in its official association with the Leipzig Book Fair and its comprehensive programming for manga and comic fans. Revenue streams likely include exhibitor fees, sponsorships, and event ticketing. The target audience is broad within the manga and cosplay community, supported by active social media channels. The partnership ecosystem includes Leipzig Book Fair and Leipziger Messe GmbH, enhancing credibility and reach. Strategic observations suggest continued growth potential through expanded event programming and digital engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent with granular controls, and no visible vulnerabilities or exposed sensitive data. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Compliance with GDPR is evident through the consent banner and privacy policy. No critical security issues were detected, but adding security headers and a security.txt file would strengthen defenses and trust.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency by providing more detailed data retention and privacy practices in the privacy policy.
  5. Regularly audit third-party scripts and embedded content for security and privacy compliance.

Technical notes

Notes

The website uses a modern JavaScript-based front end with deferred script loading and preloaded fonts for performance. Google Tag Manager is used for analytics and tracking, integrated with a consent management platform to comply with privacy laws. The site is mobile optimized and accessible, with clear navigation and multilingual support. Hosting appears to be managed by Leipziger Messe GmbH, indicated by nameservers. Performance is moderate with room for optimization. No CMS was explicitly detected, suggesting a custom or proprietary solution. Embedded YouTube videos are lazy-loaded with consent gating, enhancing privacy 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.
