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 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. 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

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 Literaturhaus Zürich occupies a significant position in the cultural sector of Zürich, leveraging its long history and reputation to attract a broad audience interested in literary arts. Its business model is non-profit, focusing on cultural enrichment rather than commercial gain. Revenue streams likely include memberships, donations, event ticket sales, and possibly grants. The organization targets literature enthusiasts, academics, and the general public. The website's integration with library catalog search and event programming indicates a comprehensive service offering. Partnerships with social media platforms and use of Google Analytics suggest a data-driven approach to audience engagement. The absence of commercial advertising and affiliate programs aligns with its non-profit status. Strategic observations include the opportunity to enhance security transparency and incident response readiness to further build trust.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and multiple security headers configured, reducing common web vulnerabilities. The use of Borlabs Cookie for consent management indicates attention to privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy or incident response contact limits transparency and preparedness perception. There is no evidence of a vulnerability disclosure program or security.txt file, which could be improved to encourage responsible reporting. Overall, the security maturity is good but could benefit from formalized policies and communication channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize an incident response contact email or form to handle security issues.
  3. Implement a vulnerability disclosure policy and consider adding a security.txt file.
  4. Enhance website accessibility features to improve inclusivity and compliance.
  5. Regularly review and update third-party plugins and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building and WooCommerce for e-commerce capabilities, although the primary business is non-profit. The tech stack includes advanced plugins like JetEngine, JetTabs, and JetElements, providing rich interactive features. Google Fonts and Swiper.js are used for typography and slideshow effects respectively. The site employs lazy loading for images and has a cookie consent mechanism via Borlabs Cookie. Performance is moderate, with room for optimization in loading speed. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Hosting provider details are not explicitly identified. The site is mobile optimized with good navigation clarity. Technical risks are minimal but depend on timely plugin updates and security monitoring.
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.
