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

4 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. 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  4. 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 theater operates as a public cultural venue with a focus on community engagement and education. Its business model revolves around ticket sales for performances and educational theater programs. The website reflects a stable local presence with consistent branding and official contact information. Partnerships with ticketing platforms like Eventim are evident. The absence of social media links suggests a focus on direct community interaction rather than broad digital marketing. Growth potential lies in expanding digital engagement and enhancing online ticket sales capabilities.

Security posture

The current security maturity is moderate. The website uses HTTPS (assumed from URL), but lacks visible security headers such as CSP or HSTS. The use of an outdated jQuery version poses potential vulnerabilities. No incident response or vulnerability disclosure information is provided, which limits transparency. Cookie consent is implemented, supporting privacy compliance. Recommendations include updating libraries, adding security headers, and publishing security policies to improve trust and resilience.

Recommendations

  1. Update jQuery and other JavaScript libraries to latest secure versions.
  2. Implement HTTP security headers including Content Security Policy and HSTS.
  3. Publish a clear security policy and incident response contact information.
  4. Enhance privacy compliance details, including GDPR-specific disclosures.
  5. Consider adding social media links and analytics for better user engagement and insights.

Technical notes

Notes

The website is built on the ikiss CMS platform with jQuery 1.12.4 and Flexslider for UI components. It uses Slicknav for mobile navigation and includes a cookie consent mechanism. The site is moderately performant with good mobile and accessibility features. SEO is supported by meta tags and Open Graph data, though no JSON-LD structured data is present. The hosting provider is not explicitly identified, but DNS uses Advantic GmbH name servers, which also designed the site. Technical debt includes outdated JavaScript libraries and lack of modern security headers, which should be addressed to reduce 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.
