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

6 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

Cronos Leuven operates as an essential entity in the technology sector, specifically targeting entrepreneurship and digital services in the Leuven region. Its competitive advantage lies in its extensive ecosystem supporting over 600 companies and 7000 employees since 1991. The business model integrates consulting, software development, and talent acquisition, positioning it as a regional hub for startups and established companies alike. The presence of detailed case studies and client logos indicates a mature partnership ecosystem. Growth indicators include active job postings and internship offers, suggesting ongoing expansion and talent acquisition efforts.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent mechanisms in place. No explicit security policies or incident response contacts are published, indicating potential gaps in formal security governance. The absence of security headers and vulnerability disclosures suggests room for improvement. Data protection practices appear aligned with GDPR, but the lack of a named Data Protection Officer or detailed privacy governance documents may be a compliance risk. Overall, the security posture is adequate for the business type but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options to strengthen site security.
  2. Publish explicit security policy and incident response information to improve transparency and preparedness.
  3. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  4. Designate and disclose a Data Protection Officer or privacy contact to enhance GDPR compliance.
  5. Enhance accessibility features and conduct performance optimizations to improve user experience and SEO.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform utilizing popular front-end libraries like jQuery and Bootstrap 4, ensuring responsive design and interactive UI elements. The inclusion of animation libraries (AOS) and carousel components (Splide.js) adds to user engagement. External resources are loaded from reputable CDNs, though some dependencies on third-party domains could impact performance or privacy. The site lacks explicit CMS identification and hosting provider details, which could be clarified for operational transparency. Performance is moderate with opportunities for optimization, especially in loading times and accessibility 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.
