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

5 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  2. 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 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';…

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

DEEP operates in the competitive IT services market with a focus on cloud, AI, data, and cybersecurity solutions. Their business model centers on consulting and managed services tailored to the needs of businesses and public sector clients in Luxembourg and France. The multilingual website and professional branding indicate a medium-sized company with regional influence. The lack of publicly available WHOIS data is offset by the professional presentation and compliance with privacy regulations. DEEP's key competitive advantages include a broad service portfolio, expertise in emerging technologies like AI, and a strong emphasis on cybersecurity. The company appears to maintain a moderate growth trajectory with a focus on digital transformation partnerships. No direct partnerships or subsidiaries were identified from the website content.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms, indicating attention to security and privacy compliance. However, no explicit security policies, incident response contacts, or vulnerability disclosure programs were found, which are recommended best practices for IT service providers. The absence of security headers in the source code suggests potential improvements in hardening the web server configuration. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is good but could be enhanced by publishing formal security policies and incident response information to increase transparency and trust.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve web security.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to improve compliance with standards and user experience for all visitors.
  5. Maintain and regularly update cookie consent and privacy compliance mechanisms to align with evolving regulations.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging a modern tech stack including jQuery, Bootstrap, React, and Clay UI components. The site is multilingual and mobile-optimized, providing a good user experience across devices. Performance is moderate, with multiple combined scripts and stylesheets loaded via combo URLs. The presence of OneTrust for cookie consent indicates compliance with privacy regulations. No major technical debt or obsolete technologies were detected, though improvements in accessibility and security headers could be made. Hosting provider details are not explicitly disclosed. Overall, the technical infrastructure supports the business needs effectively with room for incremental improvements.
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.
