Medium risk. 3 critical or high findings in Security headers and SSL/TLS.

Security score

74/100

Risk levelMedium

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

Jyväskylän kaupunginteatteri is the official city theatre of Jyväskylä, Finland, providing theatrical and cultural services to the local community. The website is hosted on a modern Drupal 10 CMS platform and integrates trusted third-party services for analytics and marketing, including Google Tag Manager and Trustmary. The site is well-branded and professionally designed, targeting a general audience interested in cultural events. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks advanced security headers and a public security policy. Privacy compliance is partial due to the absence of a visible privacy policy and terms of service. Overall, the website reflects a credible municipal cultural institution with room for improvement in transparency and security documentation.

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

3 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 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 theatre operates as a public cultural institution under the City of Jyväskylä, serving local residents and visitors interested in performing arts. Its business model is supported by municipal funding, focusing on cultural enrichment rather than commercial revenue. The website's integration with city analytics and cookie consent tools indicates compliance with Finnish and EU regulations. The absence of direct contact details on the main pages suggests reliance on centralized city contact points. The theatre maintains a consistent brand presence and leverages digital tools to engage its audience, positioning itself as a key cultural player in the region.

Security posture

The website enforces HTTPS and uses cookie consent mechanisms, which are positive security practices. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. No incident response or security policy information is publicly available, limiting transparency. Third-party scripts are from reputable sources, but continuous monitoring is recommended. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security posture is moderate but could be strengthened with additional controls and documentation.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add clear contact information including security incident response contacts to enhance trust and readiness.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

Technical notes

Notes

The website is built on Drupal 10, a modern and secure CMS platform, indicating a mature technical infrastructure. It uses external services for analytics and marketing, including Google Tag Manager and Trustmary, integrated via asynchronous scripts to minimize performance impact. The site is mobile optimized and uses responsive design techniques. Performance is moderate, with room for improvement in loading speed and accessibility compliance. The presence of Google Translate integration suggests support for multilingual audiences. Overall, the technical implementation is solid but could benefit from enhanced security configurations and SEO improvements.
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.
