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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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.

    • 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

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

GTD holds a strong position in the technology sector, focusing on mission-critical software for aerospace, defense, energy, and logistics industries. Their business model centers on B2B services with a diversified portfolio including microelectronics and quantum cybersecurity through partner companies. Revenue streams are driven by long-term contracts and projects with governmental and industrial clients. The company demonstrates growth through international expansion with six offices worldwide and a broad client base. Strategic partnerships with OpenChip, LuxQuanta, and Portel enhance their technological capabilities and market reach. GTD's certifications and client logos reinforce their competitive advantage and trustworthiness in highly regulated sectors.

Security posture

GTD exhibits a mature security posture with HTTPS enabled and no exposed sensitive data. The presence of ISO 27001 and AQAP certifications indicates adherence to recognized security standards. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The website does not implement cookie consent banners, which may be a compliance gap under GDPR. Security headers are not detected, which could be enhanced to mitigate common web threats. Overall, the security maturity is good but could benefit from formalized policies and improved user-facing security information.

Recommendations

  1. Implement HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to enhance web security.
  2. Publish a dedicated security policy and incident response page including contact channels for reporting security issues.
  3. Add a cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  4. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.

Technical notes

Notes

The website is built on the Webflow CMS platform, leveraging modern web technologies including Google Tag Manager, Google Analytics, and Weglot for multilingual support. The site is well-optimized for performance and mobile responsiveness, with clean HTML and CSS. The use of external CDNs and asynchronous script loading contributes to fast page loads. There is no evidence of outdated or vulnerable libraries. The technical infrastructure supports a professional and scalable digital presence, though adding security headers and formalizing privacy consent mechanisms would further strengthen the technical posture.
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.
