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

Greenhost is a well-established Dutch company specializing in sustainable and privacy-focused web hosting, VPS, and managed cloud services. Founded in 2006, it positions itself as a leader in green hosting with a strong commitment to renewable energy, digital rights, and open internet principles. The company operates its own hardware hosted in a sustainable datacenter in Amsterdam, emphasizing independence and environmental responsibility. Technically, Greenhost employs modern virtualization (Xen) and distributed storage (Ceph) technologies, combined with a custom-built platform and service panel. The website is well-designed, mobile-optimized, and accessible, with good SEO practices and privacy-conscious analytics (Matomo). Security measures include HTTPS, DNSSEC, and a strict Content Security Policy, though some standard security headers are missing. From a security perspective, Greenhost demonstrates a mature posture with no evident vulnerabilities or exposed sensitive data. However, the absence of a cookie consent mechanism and some security headers suggests room for improvement in GDPR compliance and security hardening. The company provides a responsible disclosure policy but lacks a published security.txt file and explicit security contact emails. Overall, Greenhost presents a trustworthy, professional, and technically sound online presence with a strong focus on sustainability and privacy. Strategic enhancements in privacy compliance and security headers would further strengthen its security posture and regulatory adherence.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

    • 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

  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 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';…

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

Greenhost occupies a niche market segment focused on sustainable and privacy-respecting hosting services in the Netherlands. Its competitive advantage lies in its long-standing commitment to green energy, ownership of hardware, and open-source software use. The business model revolves around providing VPS, domain registration, web hosting, and managed services to environmentally and privacy-conscious customers, including individuals, NGOs, and social organizations. Revenue streams likely include subscription fees for hosting and managed services. The company maintains partnerships with sustainable datacenters and network providers, enhancing its green credentials and network independence. Testimonials and sustainability reports reinforce its market credibility and customer trust.

Security posture

Greenhost exhibits a solid security posture with HTTPS enforced, DNSSEC enabled, and a strict Content Security Policy restricting scripts, images, and connections to trusted sources. The use of Xen virtualization with PVH mode and Ceph storage enhances platform security and reliability. No vulnerabilities or exposed sensitive data were detected. However, the lack of some common security headers (e.g., HSTS, X-Frame-Options) and absence of a cookie consent mechanism indicate partial compliance with best practices and GDPR. The presence of a responsible disclosure page shows incident response awareness, though no direct security contact emails were found. Overall, the security maturity is good but can be improved with additional controls and transparency.

Recommendations

  1. Implement a comprehensive cookie consent mechanism to ensure full GDPR compliance.
  2. Add standard security headers such as Strict-Transport-Security, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  3. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  4. Provide explicit security and abuse contact emails on the website for incident response.
  5. Regularly review and update privacy and security policies to maintain compliance with evolving regulations.

Technical notes

Notes

The website is built on a custom platform using modern web standards (HTML5, CSS3, JavaScript) and leverages advanced virtualization (Xen) and distributed storage (Ceph) technologies. Hosting is done in a sustainable datacenter with renewable energy, reflecting the company’s green ethos. The site loads quickly, is mobile-optimized, and accessible, with good SEO metadata and Open Graph tags. Analytics are handled via Matomo, supporting privacy-conscious data collection. The technical stack is modern and well-maintained, with no signs of outdated or vulnerable libraries. Opportunities exist to enhance security headers and implement cookie consent for improved compliance and security posture.
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.
