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

Arsys Internet S.L.U. is a well-established European technology company specializing in domain registration, web hosting, cloud services, and managed IT solutions. With over 25 years of experience, Arsys targets businesses and individuals primarily in France, Spain, Portugal, and English-speaking markets. Their offerings include domain sales, professional email, WordPress and ecommerce hosting, VPS and dedicated servers, and comprehensive cloud solutions with a focus on European data sovereignty. Technically, the website demonstrates a mature digital infrastructure with modern web technologies, responsive design, and integration of advanced analytics and error monitoring tools such as Sentry and Tune. The presence of structured data enhances SEO and business transparency. The hosting environment appears robust, likely leveraging their own or Ionos infrastructure, ensuring fast performance and good accessibility. From a security perspective, the site enforces HTTPS and uses secure cookie settings, with no visible vulnerabilities or exposed sensitive data. However, explicit security headers and a published security policy or incident response contacts are absent, representing areas for improvement. Privacy compliance is well addressed with clear privacy and cookie policies, including consent mechanisms aligned with GDPR. Overall, Arsys presents a trustworthy and professional online presence with strong business credibility and technical maturity. The lack of WHOIS data due to privacy protection slightly reduces domain trust but is justified for this business type. Strategic recommendations include enhancing security header implementation, publishing a security policy, and adding vulnerability disclosure mechanisms to further strengthen security posture and customer 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

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.

    • 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 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 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

      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

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

Business profile

Arsys operates in the competitive European hosting and domain market with a diversified portfolio of services including domain registration, hosting for various platforms (WordPress, WooCommerce, PrestaShop), cloud computing, and managed IT services. Their business model leverages recurring revenue streams from domain renewals, hosting subscriptions, and cloud usage. The company targets SMEs, enterprises, and individual professionals seeking reliable and sovereign European hosting solutions. Their multilingual websites and partner ecosystem indicate a broad geographic reach and strategic market positioning. The company emphasizes data sovereignty and compliance, appealing to customers concerned with European data protection laws. Growth indicators include a large infrastructure footprint with 100,000 servers and 30 data centers, and a strong focus on managed services and cloud innovation.

Security posture

The security posture of Arsys is solid with mandatory HTTPS encryption and secure cookie attributes. The use of Sentry for error tracking indicates proactive monitoring of application health. No sensitive data leakage or vulnerable libraries were detected in the website content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to certain web-based attacks. There is no publicly available security policy or incident response contact, which limits transparency and readiness communication. GDPR compliance is evident through privacy and cookie policies with consent mechanisms. Overall, the security maturity is good but could be improved by formalizing security governance and vulnerability disclosure processes.

Recommendations

  1. Implement and enforce comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a detailed security policy and incident response contact information on the website.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance transparency by providing data retention policies and detailed privacy compliance documentation.

Technical notes

Notes

The website is built with modern HTML5, CSS3, and JavaScript, incorporating advanced font loading and preconnect optimizations for performance. It uses third-party services such as Sentry for error monitoring and Tune for marketing analytics. The site is mobile-optimized with responsive design and accessibility considerations. Structured data in JSON-LD format is used effectively for organization and website schema, improving SEO and search engine understanding. Hosting appears to be managed by Arsys or its parent group, with a strong European data center presence. The site demonstrates good technical hygiene with no broken elements or errors detected in the provided content. Opportunities exist to further modernize security headers and enhance compliance documentation.
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.
