Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

NIS2 outside view
Not assessed
GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

No critical or high findings. These medium findings are worth fixing next.

  1. 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.

    • Medium

      No DKIM record found

      DKIM adds cryptographic signatures to emails

      What to do: Configure DKIM with your email provider

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  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.

    • Medium

      SSL Certificate Expires Within 90 Days

      SSL certificate expires in 53 days

      What to do: Plan SSL certificate renewal

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

      • CAPEC-142
      • RFC 4033
      • RFC 4035

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Medium

      Service Exposed: SSH

      Port 22 (SSH) is publicly accessible - SSH - Secure but can be brute-forced

      What to do: Review if public access to SSH is necessary

      • 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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 institution holds a strong market position as a key cultural player in the Swiss performing arts sector. Its business model revolves around ticket sales, subscriptions, cultural events, and educational outreach. The website's integration with external ticketing services and active social media presence indicates a mature digital strategy aimed at audience engagement and revenue generation. The organization maintains partnerships and sponsors, enhancing its operational and financial stability. Growth opportunities include expanding digital content and enhancing online engagement.

Security posture

The website employs HTTPS with a strong SSL configuration and includes anti-clickjacking measures. It uses reputable third-party analytics and marketing tools such as Google Analytics, Google Tag Manager, and Yoast SEO Premium. No critical vulnerabilities or exposed sensitive data were detected. However, some security headers like Content-Security-Policy and Referrer-Policy are not explicitly present and could be improved. The absence of a published security policy or incident response contact is noted. Overall, the security posture is good but can be enhanced with additional headers and formal policies.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy.
  2. Publish a formal security policy and provide incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  4. Ensure all forms have secure submission and server-side validation to prevent injection attacks.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on WordPress CMS with multilingual support via WPML and SEO optimization through Yoast SEO Premium. It uses modern web technologies including jQuery and asynchronous loading of analytics scripts. Performance is moderate with good mobile optimization and accessibility features. The site integrates external services for ticketing and video content. Technical debt appears low, but opportunities exist to enhance security headers and streamline third-party dependencies for improved performance and security.
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.
