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

Constant is a Brussels-based non-profit association focused on art and media projects, publications, and cultural signals. Established in 2007, it serves a niche audience of artists and media professionals primarily in Belgium and the broader European region. The website provides multilingual content in English, French, and Dutch, reflecting its regional engagement. The business model centers on cultural and media project facilitation rather than commercial sales. Technically, the website uses standard web technologies including HTML5, CSS, and JavaScript, with a CMS likely based on SPIP. Hosting is provided by Gandi SAS, a reputable registrar and hosting provider. The site employs iframe navigation and basic mobile optimization, with moderate performance and SEO features. No advanced frameworks or analytics services are detected, indicating a simple but functional technical infrastructure. From a security perspective, the site uses HTTPS (implied by domain and hosting provider), but lacks DNSSEC and security headers such as CSP or HSTS. No privacy or cookie policies are present, which is a compliance gap under GDPR. No incident response or vulnerability disclosure information is published. The WHOIS data is consistent and transparent, supporting legitimacy. Overall, the security posture is moderate but could be improved with standard best practices. The overall risk is low given the non-commercial nature and limited data collection, but compliance and security improvements are recommended to enhance trust and protect user data. Strategic recommendations include implementing privacy and cookie policies, enabling DNSSEC, adding security headers, and improving SSL/TLS configurations.

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

8 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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

Constant operates as a small, specialized cultural association in the media sector, focusing on art and media projects and publications. Its market position is niche, targeting artists and cultural professionals. The organization benefits from a long-established domain and physical presence in Brussels, enhancing credibility. The business model is non-profit and project-driven, with no evident commercial transactions on the website. Partnerships are indicated by related domains such as gitlab.constantvzw.org and calibre.constantvzw.org, suggesting internal project hosting and publication management. Growth indicators are limited but the multilingual approach and consistent branding support stable community engagement.

Security posture

The security maturity level is basic to moderate. HTTPS is presumably enabled but no DNSSEC or security headers are implemented, exposing the site to potential risks such as DNS spoofing and clickjacking. No privacy or cookie policies are present, indicating GDPR compliance gaps. No incident response or vulnerability disclosure mechanisms are published, limiting transparency in security management. The absence of analytics and tracking reduces privacy risks but also limits user behavior insights. Overall, the security culture appears minimal but not negligent, with room for significant improvements to align with best practices and regulatory requirements.

Recommendations

  1. Implement a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Enable DNSSEC on the domain to improve DNS security and prevent spoofing attacks.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Publish an incident response and vulnerability disclosure policy to enhance transparency and trust.
  5. Improve SSL/TLS configuration and verify HTTPS enforcement across all site pages.

Technical notes

Notes

The website uses a simple technology stack with HTML, CSS, and JavaScript, likely managed via the SPIP CMS. Hosting is through Gandi SAS, a reputable provider. The site uses iframe-based navigation which may affect SEO and accessibility negatively. Mobile optimization is basic but present. No modern JavaScript frameworks or analytics tools are detected, indicating low technical complexity. Performance is moderate, with no explicit indicators of slow loading or errors. Technical debt appears low but modernization opportunities exist, especially in improving security headers, SEO, and accessibility features.
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.
