Risk levelMedium

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

Galerie Smečky is a Prague-based cultural exhibition space specializing in contemporary art and a significant collection of Czech collage art owned by Pražská plynárenská. The website reflects a medium-sized cultural institution with a clear focus on art exhibitions and events. Technically, the site is built on Drupal 10 with modern front-end libraries such as Bootstrap and Slick Carousel, and integrates third-party services like Google Tag Manager and Cookiebot for analytics and cookie compliance. The security posture is moderate with a cookie consent mechanism in place but lacks visible security headers and explicit privacy or terms of service documentation. The domain is well-established since 2005, consistent with the business history, and no blocking or WAF mechanisms interfere with content access.

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

2 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. 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 website positions Galerie Smečky as a niche cultural institution with a specialized art collection, targeting art enthusiasts and the general public interested in Czech art. The business model is centered on exhibition hosting and cultural engagement, supported by a corporate parent company. The site leverages standard web technologies and third-party services for marketing and analytics, indicating a moderate level of digital maturity. However, the absence of direct contact information and formal policies suggests room for improvement in transparency and user engagement. The partnership ecosystem includes Google and Cookiebot services, but no direct business partner domains were identified.

Security posture

The security maturity level is moderate. The site uses HTTPS (implied by external scripts loaded over HTTPS) and implements a cookie consent banner with granular controls, which is positive for GDPR compliance. However, no explicit security headers were detected in the provided data, and there is no visible incident response or vulnerability disclosure information. The lack of a privacy policy and terms of service pages reduces compliance confidence. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is adequate but could benefit from enhanced documentation and technical controls.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website.
  2. Add terms of service and security policy documentation to improve transparency and compliance.
  3. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  5. Consider adding a security.txt file to facilitate vulnerability disclosure and incident reporting.

Technical notes

Notes

The website is built on Drupal 10 CMS, using Bootstrap 5.2.3 for responsive design and Slick Carousel for content sliders. It integrates Mapbox GL JS for map functionality and Cookiebot for cookie consent management. Google Tag Manager is used for analytics and marketing tags. The site appears mobile-optimized with responsive CSS and meta viewport tags. Performance is moderate given the use of multiple external scripts and media content such as videos and large images. Accessibility features are basic but present, including ARIA roles and labels. SEO optimization is basic with meta tags and canonical links but no structured data or Open Graph tags detected in the provided content. Hosting provider details are not explicitly available.
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.
