Open Cosmos Ltd. · Technology · United Kingdom
Low risk. 1 critical or high finding in SSL/TLS.
Open Cosmos Ltd. is a technology company specializing in the design, build, and operation of space missions, providing accessible satellite data and insights globally. The company offers end-to-end satellite mission services including assembly, launch, in-orbit operations, and data delivery. Their innovative OpenConstellation platform enables shared satellite infrastructure to address global challenges such as climate change and natural resource management. With multiple European offices and a strong social media presence, Open Cosmos positions itself as a key player in the satellite data and earth observation market. Technically, the website is built on modern web technologies including Webflow CMS, Google Fonts, and Google Tag Manager for analytics. The site is well-optimized for performance, mobile responsiveness, and accessibility, featuring a professional design and clear navigation. Cookie consent mechanisms and privacy policies indicate good privacy compliance. However, explicit security headers and incident response information are absent, representing areas for improvement. Security posture is solid with HTTPS enforced and no visible vulnerabilities or sensitive data exposure. The lack of WHOIS transparency slightly reduces trust but the overall business credibility remains high due to consistent branding, multiple physical addresses, and professional content. The site uses Google Analytics for moderate user tracking with good privacy compliance. Overall, Open Cosmos demonstrates a mature digital presence with strong business credibility and technical implementation. Strategic recommendations include enhancing security headers, publishing security policies, and improving WHOIS transparency to further strengthen trust and compliance.
Scanned
NIS2 Art. 21(2)
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.
1 finding rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
