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

IONOS Cloud S.L.U. operates the website www.ionos.es, positioning itself as the largest hosting provider in Europe and a specialist in cloud solutions. The company offers a broad range of services including domain registration, web hosting, cloud infrastructure, email and office solutions, and e-commerce platforms. The website targets businesses and individuals seeking reliable and scalable web services. The business is well-established, founded in 2001, and operates primarily in Spain with enterprise scale. The website content is professionally presented, with clear navigation and consistent branding, supporting its market position as a trusted technology provider. From a technical perspective, the website leverages modern web technologies such as Next.js and React, ensuring a responsive and performant user experience. The site is mobile-optimized and includes SEO best practices, although accessibility features are basic. Security is well-handled with HTTPS and asynchronous script loading, but explicit security headers and policies are not disclosed. Marketing tools like Kameleoon and Adobe Target are used for A/B testing and user engagement, with moderate user tracking observed. Security posture is solid but could be improved by publishing explicit security policies, incident response contacts, and vulnerability disclosure programs. Privacy compliance is currently weak due to the absence of visible privacy and cookie policies or consent mechanisms, which is a critical area for improvement given GDPR requirements. Contact information is clearly provided, enhancing business credibility. Overall, the website is a professional, trustworthy platform with strong business credibility and technical implementation. Strategic improvements in privacy compliance and security transparency would enhance its security posture and regulatory adherence.

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

2 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

IONOS holds a strong market position as Europe's largest hosting provider, focusing on cloud and web services. Its business model is service-oriented, targeting SMEs and enterprises needing domains, hosting, cloud, and email solutions. The company benefits from a broad portfolio, including specialized hosting for WordPress, e-commerce, and dedicated servers. The presence of AI-powered tools and marketing solutions indicates innovation and adaptation to market trends. The company maintains a consistent branding and professional online presence, supporting customer trust and retention. Partnerships and integrations with major platforms like Microsoft 365 and Google Workspace expand its ecosystem. Growth indicators include new product launches (e.g., VPS Linux marked as 'Nuevo') and continuous service diversification.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. However, the lack of explicit security headers (e.g., CSP, HSTS) and absence of published security policies or incident response contacts represent gaps in transparency and readiness. No vulnerability disclosure or security.txt files were found, limiting external reporting channels. Marketing and tracking scripts are present but do not indicate excessive or intrusive tracking. The site does not show signs of malware or phishing. Compliance with GDPR is not clearly demonstrated due to missing privacy and cookie policies. Overall, security practices are good but could be enhanced by formalizing policies and improving user privacy controls.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement and disclose a security policy and incident response contact information.
  3. Add a vulnerability disclosure program and security.txt file to facilitate responsible reporting.
  4. Enhance security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  5. Improve accessibility features to meet WCAG standards and enhance user inclusivity.

Technical notes

Notes

The website is built on a modern JavaScript framework (Next.js) with React, enabling server-side rendering and improved performance. It uses asynchronous and deferred loading for scripts to optimize page load times. The site is mobile-optimized with responsive design and includes SEO-friendly meta tags and structured data (JSON-LD). Hosting appears to be managed internally or via IONOS infrastructure, ensuring control over performance and security. Some technical debt is noted in the absence of explicit security headers and limited accessibility features. Opportunities exist to modernize privacy compliance mechanisms and enhance security transparency to align with best practices.
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.
