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

Hostsharing eG is a German cooperative hosting provider established in 2000, specializing in community-owned cloud infrastructure and managed hosting services. The company emphasizes sustainability, digital sovereignty, and the use of free software, targeting organizations, businesses, freelancers, and associations seeking ethical and cooperative IT solutions. Their offerings include cloud servers, private clouds, managed webspace, container servers, and comprehensive IT consulting and operations services. The website is professionally designed, mobile-optimized, and rich in content, reflecting a mature digital presence. Technically, the site is built using the Hugo static site generator with Bootstrap for responsive design and includes modern SEO and accessibility features. The infrastructure is supported by a Tier 3 data center with ISO certifications (9001, 27001, 50001), indicating a strong commitment to quality and security standards. The website uses HTTPS exclusively, but lacks some advanced security headers and a cookie consent mechanism, which are recommended for enhanced security and compliance. Security posture is solid with no visible vulnerabilities or exposed sensitive data, but the absence of WHOIS registration data for the domain raises concerns about domain legitimacy and registration transparency. Despite this, the business information and contact details are clear and trustworthy, supported by certifications and detailed legal documentation. Overall, the site demonstrates a high level of professionalism and trustworthiness, though domain registration verification is advised. Strategic recommendations include implementing explicit security headers, adding a cookie consent banner to improve GDPR compliance, publishing a security policy and incident response information, and establishing a vulnerability disclosure program to enhance security transparency and user 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

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.

    • 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048
  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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

Hostsharing eG operates in the niche cooperative hosting market, leveraging a unique business model focused on community ownership and sustainability. Their competitive advantage lies in their long-standing presence since 2000, ISO certifications, and commitment to free software and digital sovereignty. Revenue streams likely include hosting subscriptions, managed services, consulting, and cooperative memberships. The target customer segments are diverse, including enterprises, freelancers, associations, and cooperatives valuing ethical IT solutions. The company maintains a strong partnership ecosystem visible through social media and related domains. Growth indicators include recent sustainability reports and continuous service expansion. The cooperative model fosters customer loyalty and community engagement, positioning Hostsharing as a trusted alternative to commercial hosting providers.

Security posture

Hostsharing eG exhibits a mature security posture with HTTPS enforced site-wide and no visible security vulnerabilities or exposed sensitive data. The presence of ISO 27001 certification indicates adherence to recognized information security management standards. However, the website lacks explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which could further harden security. There is no publicly available security policy or incident response information, nor a vulnerability disclosure program, which are best practices for transparency and preparedness. GDPR compliance is supported by a comprehensive privacy policy, but the absence of a cookie consent mechanism is a compliance gap. Incident response readiness and security culture indicators are not explicitly documented. Overall, the security posture is strong but could be improved with enhanced transparency and technical controls.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen site security.
  2. Add a cookie consent mechanism to ensure full GDPR compliance and user privacy transparency.
  3. Publish a detailed security policy and incident response plan accessible to users and stakeholders.
  4. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  5. Verify and update domain WHOIS registration information to improve domain legitimacy and trust.

Technical notes

Notes

The website is built using the Hugo static site generator, leveraging Bootstrap for responsive design and Pagefind for search functionality. The use of JSON-LD structured data enhances SEO and semantic understanding by search engines. The site is hosted presumably on a secure infrastructure with HTTPS enabled and optimized for fast loading and mobile devices. The technical stack is modern and well-maintained, with no deprecated or vulnerable libraries detected. The site architecture supports clear navigation and accessibility. Opportunities for modernization include adding advanced security headers and cookie consent tools. Technical risks are minimal but domain WHOIS data absence could pose trust issues for users and partners.
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.
