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

3 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.

    • 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

  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

CSE operates as an essential entity in the finance sector, providing trading platforms and market data services. Its business model revolves around transaction fees, listing fees, and value-added services for market participants. The website reflects a professional and consistent brand image, leveraging modern web technologies to engage its audience. The presence of Google Analytics and Facebook Pixel indicates active marketing and user engagement tracking. However, the absence of explicit privacy and terms of service pages suggests room for improvement in compliance and transparency. The CSE's partnerships and external links primarily include trusted service providers and content delivery networks, reinforcing its operational reliability.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, valid SSL certificates, and implementation of key security headers such as HSTS, X-Content-Type-Options, and X-Frame-Options. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a public security policy, vulnerability disclosure program, or incident response contact information limits transparency and may hinder rapid response to security incidents. The use of multiple third-party scripts necessitates ongoing monitoring to mitigate supply chain risks. Overall, the security maturity is good but could be enhanced by formalizing security governance disclosures.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Develop and make publicly available a security policy and vulnerability disclosure program to enhance transparency and incident response readiness.
  3. Conduct regular security audits of third-party scripts and dependencies to prevent supply chain vulnerabilities.
  4. Enhance website accessibility features to meet international standards and improve user experience for all visitors.
  5. Implement clear data retention and user data management policies aligned with GDPR and other relevant regulations.

Technical notes

Notes

The website employs a modern technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, Font Awesome and Remixicon for icons, and Google Fonts for typography. It integrates Google Tag Manager, Google Analytics, and Facebook Pixel for analytics and marketing. The use of Dialogflow Messenger indicates an investment in interactive user support. Performance is moderate with room for optimization, especially in script loading and asset management. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed but the presence of Google Maps API and CDN usage indicates a robust infrastructure.
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.
