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

Comino Holding Ltd. is a UK-based technology company specializing in the design and manufacture of high-performance liquid-cooled computing devices, including GPU and FPGA-based supercomputers, render stations, and AI workstations. The company targets professional and enterprise customers requiring advanced computing power for AI inference, training, rendering, scientific research, and cryptocurrency mining. Comino positions itself as a niche leader in liquid cooling technology, offering patented copper water cooling systems and comprehensive warranty and support services. The website reflects a mature digital presence with excellent content quality, clear navigation, and strong branding consistency. Technically, the site leverages modern web technologies such as Webflow CMS, Google Analytics, and CookieHub for compliance, ensuring good performance and mobile optimization. Security posture is strong with HTTPS, security headers, and anti-bot measures, though the absence of a public security policy and incident response contact is noted. Overall, the domain registration data aligns well with the business claims, enhancing trustworthiness. Strategic recommendations include publishing detailed security and incident response policies and establishing a vulnerability disclosure program to further strengthen security maturity.

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

4 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 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

  3. 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

Comino operates in the high-performance computing hardware sector with a focus on liquid cooling solutions for GPUs and FPGAs. Their business model includes direct sales of workstations, servers, and cooling components, as well as OEM/ODM services. The company serves industries such as AI, rendering, forensic password recovery, and virtual production. Their partnership with AMD and presence of customer testimonials indicate a solid market position. The product range is broad, covering from compact workstations to mobile data centers, targeting medium to large enterprises and specialist professionals. The company demonstrates growth potential through continuous product innovation and strategic partnerships. The website's integration with grando.ai suggests a collaborative ecosystem enhancing their AI hardware offerings.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and use of Google reCAPTCHA to protect forms. Cookie consent is managed via CookieHub, ensuring GDPR compliance. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a dedicated security policy page and incident response contact channels limits transparency and preparedness perception. There is no published vulnerability disclosure policy or security.txt file, which are recommended best practices. Overall, the security maturity is good but can be improved by formalizing and publishing security governance documents and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and data protection measures.
  2. Establish and publicize incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update cookie and privacy policies to maintain compliance with evolving regulations.
  5. Enhance transparency by providing more detailed information on data retention and processing practices.

Technical notes

Notes

The website is built on the Webflow platform, utilizing modern JavaScript libraries including jQuery and various analytics and tracking tools such as Google Analytics, Google Tag Manager, Smartlook, and Koala. The site is well-optimized for performance and mobile responsiveness, with valid HTML and CSS. SEO best practices are followed with appropriate meta tags and structured data (JSON-LD) describing products and offers. The use of CookieHub ensures robust cookie consent management. Hosting is via Webflow's CDN, contributing to fast load times. Technical risks are minimal, with no outdated or vulnerable libraries detected. Opportunities exist to enhance security posture by adding formal security documentation and incident response mechanisms.
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.
