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

carbon-connect AG is a Swiss-based company specializing in ESG and sustainability consulting, focusing on CO2 footprint calculation, emissions reduction strategies, and climate protection projects. Established in 2013, it serves primarily SMEs, non-profits, and public sector clients in the DACH region. The company offers a comprehensive suite of services including corporate and product carbon footprinting, sustainability reporting, and verified climate compensation projects. Their market position is strengthened by ISO 9001 certification and a broad partner network. Technically, the website is built on Webflow CMS with integrations to HubSpot for forms and analytics, and Google Tag Manager for marketing and tracking. The site is well-optimized for performance, mobile responsiveness, and SEO, employing modern web technologies and consent management mechanisms to comply with GDPR. From a security perspective, the site enforces HTTPS and integrates cookie consent with Google Consent Mode and HubSpot. While no critical vulnerabilities or exposed sensitive data were found, the absence of explicit security headers and a published security policy or incident response contact are areas for improvement. No vulnerability disclosure or security.txt file is present. Overall, the website demonstrates a high level of professionalism, trustworthiness, and compliance with privacy regulations. The business is legitimate, transparent, and well-positioned in its niche. Strategic recommendations include enhancing security headers, publishing a security policy, and adding vulnerability disclosure information to further strengthen trust and security posture.

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

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  2. 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

carbon-connect AG operates in the climate protection and sustainability consulting sector, targeting SMEs and organizations in Switzerland, Austria, and Germany. Their competitive advantage lies in their pragmatic, certified approach to CO2 accounting and climate strategy development, backed by recognized standards like GHG Protocol and ISO 14064. Revenue streams likely include consulting fees, carbon offset project sales, and flexible consulting packages. The company maintains a strong partnership ecosystem with regional and industry-specific organizations, enhancing credibility and market reach. Growth indicators include a comprehensive service portfolio, active blog and resource section, and visible client logos. The company emphasizes transparency and trust through certifications and clear contact information.

Security posture

The website exhibits a mature security posture with enforced HTTPS, cookie consent management, and integration of Google Consent Mode with HubSpot analytics. No critical security issues or vulnerabilities were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a minor gap. There is no publicly available security policy or incident response contact, which could be improved to enhance incident handling readiness. No vulnerability disclosure or security.txt file was found, limiting transparency for security researchers. Overall, the security posture is good but could benefit from additional hardening and transparency measures.

Recommendations

  1. Implement explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly review and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  5. Continue to monitor and optimize privacy compliance mechanisms, ensuring ongoing adherence to GDPR and related regulations.

Notes

The website is built using Webflow CMS, leveraging modern front-end technologies including Google Fonts, jQuery 3.5.1, and Hyphenopoly for text hyphenation. It integrates HubSpot for forms, messaging, and analytics, and Google Tag Manager for marketing and tracking. The site is hosted on Webflow's CDN, ensuring fast load times and global availability. The design is responsive and optimized for mobile devices, with good accessibility features. SEO is supported by comprehensive meta tags, Open Graph, and structured JSON-LD data describing the organization. The technical implementation is robust, with minor opportunities for improvement in security header implementation and explicit performance metrics.
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.
