From a security perspective, the site enforces HTTPS and has implemented cookie consent, but lacks explicit security headers and a public security policy or incident response contact. No vulnerabilities or exposed sensitive data were detected in the content. The absence of WHOIS registration data is a concern and reduces overall trustworthiness. Overall, CS GROUP's website is professional, secure, and compliant with privacy regulations, serving a specialized and critical market segment.

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

8 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 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

      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

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

CS GROUP positions itself as a specialized integrator and operator of critical ICT systems for demanding markets such as defense, space, and energy. Their competitive advantage lies in their differentiated approach and engagement in innovative projects. The company operates subsidiaries in North America, Romania, and Germany, indicating international reach. Revenue streams likely include system design, integration services, cybersecurity solutions, and data intelligence offerings. The target customers are organizations with critical operational needs requiring secure and intelligent systems. Growth indicators include active R&D projects and participation in industry events. The partnership ecosystem includes subsidiaries and technology collaborators. The website content and structure support a strong market presence and professional operations.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and cookie consent compliance. No exposed credentials or sensitive data were found. However, the absence of security headers such as Content-Security-Policy and lack of a public security policy or incident response contact indicate areas for improvement. Compliance with GDPR is evident through privacy and cookie policies. The use of third-party analytics and marketing scripts requires ongoing monitoring to mitigate privacy risks. Overall, the security posture is solid but could be enhanced by adding explicit security policies and improving header configurations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Verify and update WHOIS domain registration information to ensure consistency and trustworthiness.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and plugins for vulnerabilities and privacy compliance.

Technical notes

Notes

The website is built on a WordPress CMS platform using a modern tech stack including Yoast SEO for optimization, Revolution Slider for visual content, and WPML for multilingual support. The site loads with moderate performance and is mobile responsive. The use of Google Fonts and jQuery is standard. Cookie consent and analytics scripts are properly integrated. There is no indication of outdated or vulnerable libraries in the visible content. The technical infrastructure supports a professional and functional web presence with opportunities for performance tuning and enhanced security configurations.
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.
