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

The Ravestijn Gallery is a leading photography gallery based in the Netherlands, specializing in exhibitions, artist representation, exclusive artwork editions, and a bookshop. The website reflects a professional art gallery business model targeting photography collectors and art enthusiasts. The company positions itself as a prominent player in the Dutch photography art market with a focus on quality and exclusivity. Technically, the website is built on the Artlogic CMS platform, utilizing jQuery and integrates Google Analytics and Google Tag Manager for visitor tracking. The site is hosted with secure HTTPS and uses Cloudinary for image hosting. Performance is moderate with good mobile optimization and accessibility features, indicating a mature digital presence. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms aligned with GDPR. However, explicit security headers are not detected, and no dedicated security or incident response policies are publicly available. No vulnerabilities or exposed sensitive data were found. The WHOIS data is consistent with the business claims, supporting domain legitimacy. Overall, the website is professional, secure, and compliant with privacy regulations, though improvements could be made in security header implementation and transparency of security policies. The risk level is low, with recommendations focusing on enhancing security posture and compliance 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

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

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 Ravestijn Gallery operates in the media sector, specifically in photography art. Its business model includes direct sales through exhibitions, participation in art fairs, and an online bookshop. The gallery targets collectors and cultural institutions, leveraging exclusivity and curated artist representation as competitive advantages. The use of Artlogic CMS and integration with ticketing and analytics platforms indicates a well-integrated digital ecosystem. Growth indicators include active event promotion and mailing list engagement. Partnerships with Artlogic for CMS and ticketing services suggest a stable operational infrastructure.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and cookie consent mechanisms supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. There is no public incident response or security policy page, which limits transparency. The use of an older jQuery version could pose risks if not regularly patched. Overall, the site is secure for its business context but would benefit from enhanced security controls and documentation.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Upgrade jQuery to a more recent, secure version to reduce potential vulnerabilities.
  4. Regularly audit third-party scripts and dependencies for security updates and vulnerabilities.
  5. Enhance privacy compliance by detailing data retention policies and providing clearer cookie usage explanations.

Technical notes

Notes

The website is built on Artlogic CMS with jQuery 1.12.4 and integrates Google Analytics and Tag Manager for analytics. Images are served via Cloudinary, optimizing media delivery. The site uses asynchronous script loading and deferred JavaScript to improve performance. Mobile responsiveness and accessibility features are well implemented. However, the use of an older jQuery version and lack of modern JavaScript frameworks indicate some technical debt. Performance is moderate, with opportunities to optimize loading times further. The technical stack is stable but could be modernized to enhance security and user experience.
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.
