Risk levelHigh

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

Christophe Dillinger Studio is a small, UK-based multi-disciplinary artist portfolio showcasing works primarily in sculpture, photography, and screen printing. The website serves as a digital gallery and sales platform for artworks, targeting art enthusiasts and potential buyers. The site is built on WordPress with Elementor and uses standard web technologies such as jQuery and MediaElement.js. The technical infrastructure is moderate in performance with good mobile optimization but basic SEO and accessibility features. Security posture is basic with HTTPS enabled but lacking essential security headers and no visible incident response or security policies. Privacy compliance is minimal with no privacy or cookie policies present. Contact is only available via a contact form, with no direct emails or phone numbers provided. Overall, the website is functional and professional but would benefit from enhanced security and privacy measures to improve trust and compliance.

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

11 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Network security

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

    • Critical

      Critical Service Exposed: Telnet

      Port 23 (Telnet) is publicly accessible - Telnet - Unencrypted remote access

      What to do: Immediately restrict access to Telnet using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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 · found on this site
  • 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 business operates as an individual artist studio with a niche market position focused on art collectors and enthusiasts. The business model is primarily portfolio display and direct sales of artworks. There is no evidence of partnerships, subsidiaries, or parent companies. The website content is consistent and professionally presented, but lacks trust indicators such as certifications or testimonials. The absence of direct contact details and privacy policies may limit customer confidence. Growth opportunities could include adding more comprehensive business information, social media presence, and enhanced privacy and security features.

Security posture

The current security maturity level is basic. HTTPS is implemented, but the absence of security headers such as Content-Security-Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, which may hinder timely handling of security incidents. The use of standard WordPress plugins and themes requires regular updates to mitigate vulnerabilities. Privacy compliance gaps exist due to missing privacy and cookie policies. Overall, the security posture is adequate for a small personal site but insufficient for higher-risk environments.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  2. Add a clear privacy policy and cookie consent mechanism to comply with GDPR and enhance user trust.
  3. Provide direct contact information such as a company email address and phone number to improve business credibility.
  4. Establish an incident response policy and publish contact channels for security issues (e.g., security@ or abuse@ emails).
  5. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and improve performance.

Technical notes

Notes

The website is built on WordPress 6.8.1 with the Twenty Twenty theme and Elementor page builder. It uses jQuery and MediaElement.js for media handling. The site loads CSS and JS resources from its own domain and WordPress CDN domains. Performance is moderate with deferred JS loading and lazy loading for images. Mobile optimization is good with responsive design and viewport meta tags. SEO is basic with canonical links and alternate hreflang tags for English and French. Accessibility is basic with skip links and ARIA labels but lacks advanced features. No advanced hosting or CDN information is available. The site would benefit from enhanced security configurations and improved privacy compliance.
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.
