ARCHA+ is a multifunctional cultural space operating since 2024 in the premises of the original Divadlo Archa in Prague. The organization offers a diverse program of contemporary arts including music, theater, and dance, targeting a broad audience interested in cultural events. Supported by municipal and governmental bodies, ARCHA+ positions itself as a key cultural institution in Prague with a focus on education and community engagement. Technically, the website employs modern front-end technologies such as Bootstrap, jQuery, Vue.js, and integrates Google Tag Manager and Facebook Pixel for analytics and marketing, all implemented with GDPR-compliant consent mechanisms. Security posture is solid with HTTPS and cookie consent, though some security headers and explicit policies could be improved. Overall, the site is professional, trustworthy, and well-optimized for users.

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 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. 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

  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.

    • 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

ARCHA+ operates in the media and non-profit cultural sector, leveraging partnerships with local government and foundations. Its business model centers on event hosting, ticket sales, educational projects, and venue services. The organization targets cultural consumers and educational institutions, with a clear focus on contemporary arts. The website reflects a consistent brand and professional content, supporting growth and audience engagement. The presence of official logos and funding acknowledgments enhances credibility. The use of external ticketing partners like GoOut.net indicates strategic partnerships for sales and marketing.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and cookie consent mechanisms. Tracking scripts are managed with user consent, aligning with GDPR requirements. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure statements suggests room for improvement in transparency and readiness. Security headers such as Content-Security-Policy and X-Frame-Options are not explicitly detected, which could be added to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were found in the HTML content.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website uses a modern and diverse technology stack including Bootstrap for responsive design, jQuery and Vue.js for interactivity, and Swiper.js for sliders. Analytics and marketing are handled via Google Tag Manager and Facebook Pixel with proper consent. The site is mobile-optimized and SEO-friendly with appropriate meta tags and Open Graph data. Performance is moderate, with potential improvements in loading speed by optimizing scripts and assets. No CMS was explicitly detected, suggesting a custom or proprietary solution. Hosting provider details are not disclosed. Overall, the technical implementation supports a professional and user-friendly cultural website.
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.
