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

Cambridge Cleantech is a UK-based leading cleantech innovation network that connects a diverse ecosystem of innovators, investors, corporates, academics, and public sector stakeholders to foster sustainable technologies and solutions. The organization offers a range of services including technology scouting, acceleration programs, access to finance, consultancy, and membership benefits, positioning itself as a pivotal enabler in the clean technology sector. The website reflects a professional and modern digital presence built on HubSpot CMS, featuring comprehensive content, clear navigation, and mobile optimization. Security posture is strong with HTTPS, reCAPTCHA integration, and cookie consent mechanisms, although explicit security headers could be enhanced. Privacy compliance is well addressed with a clear privacy and cookie policy. The WHOIS lookup failed due to querying the subdomain rather than the domain, but this technical anomaly does not detract from the legitimacy of the business. Overall, Cambridge Cleantech demonstrates a mature digital and business presence with strong trust indicators and a clear focus on sustainability and innovation.

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.

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 · found on this site
  • 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

The company operates in the cleantech sector, targeting a broad audience including startups, investors, corporates, and public sector entities interested in climate impact and sustainability. Its business model revolves around ecosystem facilitation, networking, and providing specialized services such as technology scouting and investment matching. The presence of partner organizations and events like Cleantech Venture Day indicates active engagement and a strong market position. The company is medium-sized with clear UK registration and VAT details, enhancing credibility. The website's content and structure support its role as a knowledge and connection hub within the cleantech community.

Security posture

The website employs HTTPS with a valid SSL certificate, uses Google reCAPTCHA Enterprise to protect forms, and implements a cookie consent banner aligned with GDPR requirements. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not visibly set in the HTML source, which could be improved to enhance security against common web attacks. No vulnerabilities or exposed sensitive data were detected. The absence of a published security policy or incident response contact is a minor gap in transparency. Overall, the security posture is good but could benefit from additional header hardening and published security documentation.

Recommendations

  1. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit third-party scripts and HubSpot integrations for vulnerabilities and updates.
  4. Maintain and monitor reCAPTCHA effectiveness to prevent form abuse and spam.
  5. Enhance data retention and privacy disclosures to align with evolving GDPR and data protection standards.

Technical notes

Notes

The website is built on the HubSpot CMS platform, leveraging modern web technologies such as jQuery, Slick Carousel, Font Awesome, and Google Fonts. It integrates Google Analytics 4 for tracking and uses HubSpot's forms and cookie consent tools for marketing and compliance. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, typical for CMS-driven sites with rich media content. The technical stack is modern and well-maintained, though opportunities exist to optimize loading speed and implement additional security headers. Hosting is managed by HubSpot's EU data center, ensuring compliance with regional data protection laws.
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.
