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

4 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. 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 company operates in the real estate and hospitality sectors, focusing on creative industry clients. Its business model revolves around providing flexible office and coworking spaces, event venues, and community support for creative entrepreneurs. The presence of a newsletter and active social media channels indicates engagement with its target audience. Partnerships with Antwerp Powered by Creatives and communication agencies like Volta enhance its ecosystem. The business appears small-sized but well-rooted with a history dating back to 2002. Revenue streams likely include rental fees for offices, coworking spots, event space bookings, and catering services. The company benefits from a strong local market position as a creative hub in Antwerp.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and use of Google reCAPTCHA to protect forms from abuse. Cookie consent is managed via CookiePro, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. The use of an outdated jQuery version (1.8.3) could pose vulnerabilities if not regularly patched. No visible signs of exposed sensitive data or vulnerabilities were detected. Incident response and security policy information are not publicly available, which is common for small businesses but could be enhanced to improve trust. Overall, the security posture is adequate but could be strengthened with modern best practices.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Upgrade jQuery and other JavaScript libraries to the latest secure versions to reduce vulnerability exposure.
  3. Publish a basic security policy and incident response contact information to enhance transparency and trust.
  4. Regularly audit third-party scripts and dependencies for security and privacy compliance.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a combination of legacy and modern web technologies, including jQuery 1.8.3 and Bootstrap 3, which are functional but somewhat dated. Google Maps API integration and Google Analytics provide location and traffic insights. CookiePro manages cookie consent with a detailed preference center, indicating good privacy awareness. The site is mobile responsive and includes SEO-friendly meta tags and Open Graph data. Performance is moderate, with room for optimization. Hosting provider details are not explicit. The site structure is clear with well-organized navigation and multiple content sections. Technical risks include potential vulnerabilities from outdated libraries and missing security headers. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security controls.
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.
