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

Astranis is a technology company specializing in the design, manufacture, and operation of advanced high-orbit satellites. Their innovative approach focuses on small, radiation-hardened satellites that serve both commercial and government clients, including partnerships with major entities such as Space Force, NASA, and Chunghwa Telecom. The company positions itself as a leader in the emerging market for affordable, powerful satellites in geostationary and medium earth orbits, offering broadband and mission-critical services. Technically, the website is built on the Webflow platform, leveraging modern web technologies including Google Fonts, Google Analytics, and reCAPTCHA for security. The site is well-optimized for performance and mobile devices, with a professional design and clear navigation. However, some standard security headers are missing, and privacy and cookie policies are not explicitly presented, indicating room for improvement in compliance and security transparency. From a security perspective, the site uses HTTPS and includes anti-bot measures via reCAPTCHA, but lacks visible security policies, incident response contacts, and vulnerability disclosure mechanisms. The absence of WHOIS registration data for the domain is unusual and warrants further verification to confirm domain legitimacy. Despite this, the professional content, strong partner ecosystem, and absence of suspicious elements suggest a generally trustworthy online presence. Overall, Astranis demonstrates a solid business and technical foundation with a good security posture but should enhance privacy compliance and domain registration transparency to strengthen trust and regulatory adherence.

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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

Astranis operates in the high-technology satellite manufacturing and space communications sector, targeting commercial satellite operators and government agencies. Their competitive advantage lies in pioneering small, radiation-hardened satellites for high orbits, a niche traditionally dominated by large, expensive spacecraft. Revenue streams include satellite service contracts exceeding $1 billion and government mission partnerships. The company’s growth is supported by strategic alliances with major government and commercial entities, positioning it well in a growing market for satellite broadband and resilient space infrastructure. Their business model integrates in-house manufacturing and testing, enabling control over quality and innovation. The partnership ecosystem includes Chunghwa Telecom, Thaicom, Space Force, and NASA, reflecting a strong market presence and credibility.

Security posture

Astranis exhibits a moderate to strong security posture with HTTPS enforced and use of Google reCAPTCHA to protect forms from automated abuse. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No explicit privacy or security policies are published, and no incident response or vulnerability disclosure information is available, which may impact compliance with GDPR and other regulations. The missing WHOIS data for the domain is a concern for domain ownership transparency. Overall, the security maturity is adequate for a technology company but could be improved by implementing comprehensive security policies, publishing incident response contacts, and enhancing header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and cookie consent banner to improve GDPR compliance and user trust.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response and security contact information on the website.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Verify and update WHOIS domain registration information to ensure transparency and legitimacy.

Technical notes

Notes

The website is built on the Webflow platform, utilizing modern front-end technologies and Google services for fonts, analytics, and security. The site loads quickly and is mobile optimized with good SEO practices including meta tags and Open Graph data. The use of asynchronous scripts and deferred loading enhances performance. However, accessibility features appear basic and could be improved. The absence of visible security headers and privacy mechanisms indicates technical gaps in security implementation. The domain’s WHOIS data is missing, which is unusual and suggests a need for domain registration verification. Overall, the technical infrastructure is modern and well-implemented but could benefit from enhanced security and compliance 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.
