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

Arsys Internet S.L.U. is a well-established Spanish technology company founded in 1996, specializing in domain registration, web hosting, cloud computing, email services, and managed IT solutions. The company positions itself as a leading European provider with a strong focus on data sovereignty and comprehensive cloud infrastructure. Their website reflects a mature digital presence with professional design, clear navigation, and extensive service offerings targeting businesses and individuals seeking reliable internet presence solutions. Technically, the site employs modern web technologies, asynchronous loading of analytics and error tracking scripts, and is hosted likely by IONOS, indicating robust infrastructure. Security posture is strong with HTTPS enforced and secure cookie settings, though explicit security headers and incident response contacts are not publicly evident. The WHOIS data for the domain www.arsys.net is incomplete or missing, which raises some concerns about domain registration transparency but does not detract significantly from the overall legitimacy given the company's established brand and presence. Overall, Arsys demonstrates a solid business and technical foundation with room for improvement in security transparency and WHOIS data clarity.

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 with a diversified portfolio including cloud services, dedicated servers, and managed IT solutions. Their business model leverages direct sales, reseller partnerships, and value-added services such as SEO tools and ecommerce hosting. The company targets SMEs, enterprises, and individual professionals requiring scalable and sovereign hosting solutions. Their partnership ecosystem includes regional domains and IONOS infrastructure services, enhancing their market reach. Growth indicators include 25 years of operation and a broad service catalog. Strategic observations suggest focusing on enhancing security transparency and expanding incident response capabilities to strengthen trust further.

Security posture

The website enforces HTTPS and uses secure cookie attributes, indicating good baseline security. The presence of Sentry and IAS scripts shows active monitoring and analytics. However, the absence of explicit security headers like CSP, X-Frame-Options, and a public vulnerability disclosure or security.txt file indicates gaps in security maturity. No exposed sensitive data or vulnerable libraries were detected. Incident response contact information is not publicly available, which could hinder timely reporting and mitigation of security issues. Compliance with GDPR is inferred from privacy and cookie policies, but explicit security policy frameworks are not mentioned. Overall, the security posture is solid but could be improved by publishing detailed security policies and incident response contacts.

Recommendations

  1. Publish explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance browser security.
  2. Create and publish a security.txt file or a dedicated vulnerability disclosure page to facilitate responsible reporting of security issues.
  3. Provide clear incident response contact information, including dedicated security or abuse email addresses.
  4. Clarify domain registration details and ensure WHOIS data is accurate and publicly accessible to improve transparency and trust.
  5. Continue to monitor and update privacy and cookie policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website uses a modern tech stack including HTML5, CSS3, and JavaScript with asynchronous loading of analytics and error tracking scripts such as Sentry and IAS. The hosting is likely provided by IONOS, a reputable European provider, supporting good performance and data sovereignty. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed with meta tags, Open Graph data, and structured JSON-LD data for organization and website. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is fast with preconnect and DNS prefetch optimizations. Technical risks are minimal but include the need for enhanced security headers and incident response transparency.
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.
