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

CLS (Collecte Localisation Satellites) is a large multinational company founded in 1986, specializing in satellite data collection and Earth observation services. The company operates globally with 35 sites and focuses on environmental monitoring, maritime security, sustainable fisheries, mobility, and energy infrastructure. CLS leverages advanced technologies such as data science, AI, and machine learning to provide actionable insights to governments, environmental agencies, and industry sectors. The website reflects a mature digital presence with professional design, comprehensive content, and multilingual support. Technically, the website is built on WordPress using the Divi theme and incorporates modern JavaScript libraries like Swiper.js and GSAP. It employs HTTPS with good SSL configuration and uses hCaptcha for form security. The site includes detailed privacy and cookie policies with consent mechanisms, indicating good privacy compliance. Analytics are implemented via Google Tag Manager with moderate user tracking. From a security perspective, the site shows good practices such as HTTPS enforcement and CAPTCHA usage but lacks explicit security headers like Content-Security-Policy and X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data limits domain legitimacy verification, but the professional web presence and certifications support trustworthiness. Overall, CLS presents a strong business and technical profile with good security posture and privacy compliance. The main risk is the lack of publicly available WHOIS data, which should be further investigated to confirm domain registration legitimacy.

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

6 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

      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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn, YouTube, Google APIs

      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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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

CLS holds a strong market position as a pioneer in satellite-based Earth observation and environmental monitoring. Its business model is B2B, serving governmental and industrial clients with satellite data and digital platforms. The company benefits from its parentage by CNES and CNP, enhancing credibility and access to space technologies. CLS's growth is supported by acquisitions (e.g., Ground Control) and a broad portfolio of solutions addressing climate, maritime security, and energy sectors. The company’s global footprint and certifications indicate operational maturity and compliance. Partnerships with specialized platforms further extend its service ecosystem.

Security posture

The website demonstrates a mature security posture with HTTPS, CAPTCHA protection on forms, and no visible sensitive data leaks. However, it lacks some recommended HTTP security headers, which could improve defense against clickjacking and MIME sniffing attacks. No public incident response or security policy pages were found, which could be enhanced to improve transparency and readiness. The use of third-party plugins and scripts appears controlled, but ongoing vulnerability management is advised. Privacy policies and cookie consent mechanisms align well with GDPR requirements, indicating good compliance culture.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to strengthen security.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Regularly audit and update third-party plugins and scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Investigate and verify domain WHOIS information to confirm registration legitimacy and reduce trust concerns.

Technical notes

Notes

The website is built on WordPress with the Divi theme, leveraging modern JavaScript libraries such as Swiper.js for sliders, GSAP for animations, and Tippy.js for tooltips. It uses hCaptcha for bot protection and Google Tag Manager for analytics and marketing tags. The site is mobile-optimized with responsive design and good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with potential improvements in caching and resource optimization. Accessibility is basic but could be enhanced. The technical stack is standard for corporate websites, providing a balance of functionality and maintainability.
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.
