Security score

78/100

Risk levelLow

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

LuxQuanta Technologies S.L. is a specialized technology company focused on Quantum Key Distribution (QKD) systems that provide ultra-secure communication solutions resilient to quantum computer attacks. The company targets sectors with stringent security requirements such as telecommunications, government, finance, healthcare, and utilities. Their business model centers on integrating innovative quantum cryptography technology into existing telecommunication infrastructures, positioning themselves as a European pioneer with recognized awards and partnerships. The website demonstrates a moderate to good level of digital maturity, employing modern web technologies including HTML5, CSS3, JavaScript, Google Analytics, and reCAPTCHA for bot protection. The site is mobile optimized with good SEO practices and clear navigation, although some backend PHP warnings indicate minor technical debt. Privacy and cookie policies are implemented with consent mechanisms, reflecting compliance with GDPR. From a security perspective, the site enforces HTTPS and uses reCAPTCHA, but lacks explicit security headers and published security policies or incident response information. No vulnerability disclosure or security.txt files were found. The WHOIS data aligns well with the business claims, supporting legitimacy. Overall, the security posture is solid but could be improved by adding security headers and formal policies. The overall risk assessment is moderate with no critical issues detected. Strategic recommendations include enhancing security headers, resolving backend warnings, publishing security and incident response policies, and establishing a vulnerability disclosure program to strengthen trust and compliance.

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

2 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 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

LuxQuanta operates in the niche but growing market of quantum cryptography, targeting high-security sectors that require future-proof encryption solutions. Their competitive advantage lies in pioneering QKD technology in Europe and securing prestigious awards and partnerships with research institutes and industry leaders. The business model is B2B, focusing on telecom operators and critical infrastructure providers. Revenue streams likely include product sales, integration services, and R&D collaborations. The company demonstrates growth potential through participation in EU-funded projects and active marketing via webinars and news updates. The partnership ecosystem includes ICFO, GTD, and Corning, enhancing credibility and market reach. Strategic observations suggest a focus on innovation, compliance, and expanding adoption of quantum-secure communications.

Security posture

The website exhibits a mature security posture with mandatory HTTPS and bot protection via Google reCAPTCHA. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. Minor PHP warnings in the footer could leak information and should be fixed. No explicit security policy or incident response contact information is published, which is a gap for transparency and readiness. Lack of vulnerability disclosure or security.txt files limits external security collaboration. Overall, the security maturity is good but can be enhanced by adopting best practices and formal policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Fix PHP warnings in the footer to prevent potential information leakage.
  3. Publish a comprehensive security policy and incident response plan accessible on the website.
  4. Establish a vulnerability disclosure program and publish a security.txt file to encourage responsible reporting.
  5. Continue enhancing privacy compliance and transparency to build user trust.

Technical notes

Notes

The website uses a modern front-end stack with HTML5, CSS3, and JavaScript, including third-party services such as Google Analytics, Google Tag Manager, and reCAPTCHA. The site is mobile optimized and uses multimedia content effectively. Minor backend issues are indicated by PHP warnings in the footer, suggesting some technical debt or misconfiguration. No CMS or hosting provider is explicitly detected. Performance is moderate with preloading of fonts and scripts. SEO is good with proper meta tags and Open Graph data. Accessibility is basic but could be improved. Overall, the technical infrastructure supports a professional online presence but would benefit from backend code cleanup and enhanced 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.
