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 computing, and managed IT services. Founded in 1996 and headquartered in Logroño, Spain, Arsys positions itself as a trusted provider with 25 years of experience, offering a broad portfolio of services including email hosting, SSL certificates, and ecommerce solutions. The company targets businesses and individuals seeking reliable internet presence solutions, emphasizing European data sovereignty and comprehensive cloud infrastructure. Technically, the website employs modern web technologies including JavaScript, CSS3, and HTML5, with integrations of error tracking (Sentry) and marketing analytics (Tune.js). Hosting appears to be managed by IONOS, indicating a robust infrastructure. The site is well-optimized for mobile devices and SEO, with structured data enhancing search engine understanding. Performance is moderate, with room for improvement in accessibility features. From a security perspective, the site enforces HTTPS and uses SSL certificates, but lacks explicit security headers and published security policies or incident response information. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Privacy compliance is strong, with clear privacy and cookie policies and consent mechanisms in place. Overall, the domain WHOIS data is unavailable or protected, which slightly reduces transparency and trustworthiness. However, the professional presentation, consistent branding, and comprehensive service offerings support a positive risk assessment. Strategic recommendations include enhancing security headers, publishing detailed security policies, and improving accessibility to further strengthen the security posture 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 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

      • 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

Arsys operates in the competitive European hosting and domain registration market, leveraging its long-standing presence and broad service portfolio to maintain a strong market position. Its business model focuses on recurring revenue streams from domain registrations, hosting plans, cloud services, and managed IT solutions. The company targets SMEs, enterprises, and individual professionals requiring reliable and sovereign European hosting solutions. Partnerships and localized domains in Spain, Portugal, and France indicate a regional expansion strategy. The presence of managed services and cloud offerings suggests adaptation to evolving market demands and digital transformation trends. The company’s marketing emphasizes data sovereignty and comprehensive cloud infrastructure, appealing to privacy-conscious customers.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and SSL certificates ensuring encrypted communications. The absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No direct evidence of vulnerabilities or exposed sensitive information was found. Privacy policies and cookie consent mechanisms align with GDPR requirements, indicating compliance awareness. However, the lack of published incident response or vulnerability disclosure policies limits transparency and preparedness perception. The use of third-party scripts like Sentry and Tune requires ongoing monitoring to mitigate supply chain risks. Overall, the security posture is solid but could benefit from enhanced policy publication and technical header implementation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a comprehensive security policy and incident response plan accessible to users and partners.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and dependencies to minimize supply chain vulnerabilities.

Technical notes

Notes

The website is built using standard modern web technologies with a focus on performance and user experience. Integration with IONOS frontend services and third-party analytics tools like Sentry and Tune indicates a mature technical infrastructure. The site is mobile-optimized and SEO-friendly, with structured data enhancing search engine visibility. However, the absence of a detected CMS suggests a custom or proprietary platform. Performance is moderate, with potential for optimization in loading times and accessibility compliance. The technical stack supports scalability and multi-language content delivery, aligning with the company’s regional market focus.
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.
