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

HOSTEUR SA is a Swiss-based technology company specializing in web hosting, domain registration, cloud services, and IT management with over 20 years of experience. The company emphasizes European data sovereignty, operating datacenters exclusively in Europe, and holds multiple ISO certifications (27001, 9001, 14001) that attest to its commitment to security, quality, and environmental responsibility. The website is professionally designed, mobile-optimized, and provides comprehensive service information targeting businesses and individuals seeking secure hosting solutions. Technically, the website employs modern web technologies including Bootstrap, jQuery, Owl Carousel, and Google Fonts, with a cookie consent mechanism implemented via Tarteaucitron. The site is served over HTTPS with no visible security vulnerabilities in the HTML content. However, no explicit HTTP security headers were detected, and no CMS or hosting provider details are disclosed. Performance is moderate with good mobile optimization and basic accessibility features. From a security perspective, HOSTEUR demonstrates strong compliance with recognized standards through its ISO certifications and cookie consent implementation. The absence of WHOIS data for the domain is a notable anomaly that slightly reduces trustworthiness, though the website content and certifications support legitimacy. No incident response or vulnerability disclosure information is publicly available, indicating an area for improvement. Overall, HOSTEUR presents as a credible and professional hosting provider with a solid security posture and compliance focus. Strategic recommendations include enhancing transparency around incident response, publishing vulnerability disclosure policies, implementing additional security headers, and clarifying domain registration details to improve trust and compliance further.

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

5 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 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, LinkedIn, YouTube, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

HOSTEUR operates in the competitive European hosting and cloud services market, leveraging its long-standing experience and multiple ISO certifications as key differentiators. The company targets SMEs and larger enterprises requiring secure, compliant, and eco-responsible hosting solutions. Its business model centers on providing a broad portfolio of services including domain registration, VPS/cloud hosting, private cloud, storage solutions, and IT management (infogérance). The eco-responsible positioning and European data sovereignty focus align with growing market demand for data privacy and sustainability. The company maintains an active presence on major social media platforms and publishes relevant technical and industry articles, supporting brand awareness and customer engagement. The lack of visible WHOIS data is unusual and may warrant further investigation to ensure transparency. Overall, HOSTEUR appears well-positioned with a medium-sized operation focused on quality and compliance.

Security posture

HOSTEUR demonstrates a mature security posture evidenced by ISO 27001 certification and a clear commitment to data protection and environmental responsibility. The website is served exclusively over HTTPS and includes a cookie consent mechanism aligned with GDPR requirements. However, the absence of explicit HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options represents a potential area for enhancement. No direct contact information for incident response or vulnerability disclosure is provided, which could delay response to security incidents. No vulnerabilities or exposed sensitive data were detected in the website content. The missing WHOIS data for the domain is a concern from a trust perspective but does not directly impact technical security. Overall, the security posture is strong but could be improved with better transparency and additional technical controls.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish clear incident response and vulnerability disclosure policies, including dedicated contact channels (e.g., security@hosteur.com).
  3. Investigate and clarify domain WHOIS information to improve transparency and trustworthiness.
  4. Enhance website accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Maintain and update privacy and cookie policies regularly to ensure ongoing GDPR compliance and user trust.

Technical notes

Notes

The website uses a modern and widely adopted technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, Owl Carousel for interactive content sliders, and Google Fonts for typography. The inclusion of Tarteaucitron indicates a proactive approach to cookie consent management. The site loads external resources from reputable CDNs, enhancing performance and reliability. No CMS or hosting provider is explicitly identified, suggesting a custom or managed hosting environment. Performance is moderate with good mobile optimization but basic accessibility features. The site structure and meta tags support SEO best practices. There is an opportunity to improve technical security by adding HTTP security headers and enhancing accessibility compliance. Overall, the technical implementation is solid with room for incremental improvements.
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.
