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

Open Cosmos Ltd. is a European space infrastructure company specializing in designing, building, and operating satellite missions. The company recently acquired Connected, a Portuguese startup focused on affordable space-based IoT connectivity, to enhance its technological autonomy and expand its footprint in Portugal. Open Cosmos operates production facilities across the UK, Spain, Greece, and now Portugal, serving both commercial and institutional clients with scalable satellite infrastructure and hosted payload technology. The company maintains a strong market position with a 100% mission success rate and profitability over the past four years. Technically, the website is built on the Webflow platform, leveraging modern web technologies such as Google Fonts, jQuery, and Google Tag Manager for analytics and marketing. The site is well-optimized for performance, mobile responsiveness, and accessibility, with comprehensive metadata and SEO practices. Cookie consent mechanisms and privacy policies are implemented, reflecting good privacy compliance. From a security perspective, the site enforces HTTPS and employs cookie consent but lacks explicit security headers and a public security policy or vulnerability disclosure. No exposed sensitive data or vulnerabilities were detected in the content. The WHOIS data for the domain is unavailable, likely due to privacy protection or recent registration, which slightly impacts trust but is common for tech startups. Overall, Open Cosmos presents a credible and professional digital presence aligned with its business objectives. Strategic recommendations include enhancing security transparency, publishing a security policy, and adding vulnerability disclosure mechanisms 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

1 finding rated critical or high. Fix these first.

  1. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Open Cosmos is positioned as a key player in the European space technology sector, focusing on satellite mission services and IoT connectivity. The acquisition of Connected accelerates its capabilities in space-based IoT, enabling new market opportunities in maritime, energy, logistics, and other industries. The company benefits from strong institutional partnerships, including ESA and the Portuguese Space Agency, and has secured significant investment funding. Its business model combines hardware manufacturing, satellite operations, and data services, targeting both commercial and governmental clients. The company’s growth trajectory and strategic investments in Portugal highlight its commitment to European space sovereignty and industrial capability expansion.

Security posture

The website demonstrates a moderate to strong security posture with mandatory HTTPS and cookie consent mechanisms in place. However, it lacks advanced security headers such as Content-Security-Policy and does not publish a dedicated security policy or incident response contacts. No vulnerability disclosure or security.txt file is present, which are best practices for transparency and incident management. The absence of exposed sensitive data and the use of reputable third-party services reduce risk. Overall, the security maturity is adequate for the business type but could be improved with formalized policies and enhanced header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Add and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear incident response contact information, including security or abuse email addresses.
  5. Regularly review and audit third-party scripts and dependencies for vulnerabilities.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern web technologies including Google Fonts, jQuery, and Google Tag Manager for analytics and marketing. The site is hosted on Webflow’s CDN, ensuring fast load times and good performance. Mobile optimization and accessibility are well addressed, with responsive design and semantic HTML structure. SEO practices are implemented with comprehensive meta tags and Open Graph data. No technical debt or deprecated technologies were detected. Opportunities exist to enhance security headers and implement formal security policies to reduce risk and improve compliance.
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.
