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

Carbon Footprint Ltd operates a comprehensive online platform dedicated to carbon footprint calculation, reduction, and offsetting services targeting both businesses and individuals. The company offers a range of tools including calculators, consultancy, verification, and carbon offset projects, positioning itself as a reputable player in the sustainability and environmental sector. The website demonstrates a professional and consistent brand presence with clear navigation and relevant content supporting its market position. Technically, the website leverages modern web technologies such as Bootstrap, jQuery, and Microsoft Clarity for analytics, alongside a cookie consent mechanism ensuring privacy compliance. The site is mobile-optimized and SEO-friendly, though some accessibility features could be enhanced. The CMS used is RADsite, and external trusted partner domains are integrated for extended services. From a security perspective, the site uses HTTPS and includes cookie consent but lacks explicit security headers in the HTML content. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data for the domain is a notable concern, impacting domain trustworthiness despite the professional appearance and certifications displayed. Overall, the website presents a solid digital presence with good content quality and business credibility. Strategic improvements in security headers, WHOIS transparency, and accessibility would further strengthen its posture and trust.

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

10 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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

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

Carbon Footprint Ltd is positioned as an essential entity within the energy and non-profit sectors, focusing on environmental sustainability. Its business model revolves around providing carbon footprint calculation tools, consultancy, and offsetting services, supported by partnerships with platforms like Sustrax and CRISP. The company targets organizations and individuals committed to reducing their carbon impact, leveraging certifications such as ISO 14001 and ISO 9001 to build trust. The presence of client testimonials and quality assurance standards further enhances credibility. The company appears medium-sized with a UK base, though founding year and parent company details are not disclosed. The strategic use of partner platforms and a comprehensive service offering indicate a mature market approach with growth potential.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented, reflecting awareness of privacy and security best practices. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No incident response or security policy pages were found, indicating potential gaps in formal security governance and transparency. The absence of WHOIS data reduces domain trust and could be a risk factor. Overall, the security posture is adequate for the business type but would benefit from enhanced header configurations, documented security policies, and improved domain registration transparency to mitigate risks and comply with evolving regulations.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen site security.
  2. Publish a dedicated security policy and incident response information to improve transparency and preparedness.
  3. Investigate and resolve the missing WHOIS data issue to enhance domain trust and legitimacy.
  4. Enhance website accessibility features to meet WCAG standards and improve user experience for all visitors.
  5. Conduct regular security audits of third-party scripts and dependencies to prevent vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for interactivity, and Owl Carousel for content sliders. It integrates analytics tools such as Microsoft Clarity and Google Analytics, and uses CookieConsent2 for GDPR-compliant cookie management. The CMS identified is RADsite, a specialized content management system. Performance is moderate with room for optimization, and mobile responsiveness is good. SEO is well addressed with proper meta tags and structured navigation. However, the absence of explicit security headers and incomplete WHOIS data represent technical risks. Overall, the infrastructure supports the business needs effectively but would benefit from security and performance enhancements.
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.
