Risk levelLow

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

IONOS SARL is a well-established French subsidiary of IONOS SE, providing a comprehensive range of web hosting, domain registration, email, cloud, and e-commerce solutions targeted at both individuals and professional customers. The website demonstrates a strong market position in the European technology sector with a focus on reliable and scalable hosting services. Technically, the site is built using modern frameworks such as Next.js and employs best practices in web performance and mobile optimization. Security posture is solid with HTTPS enforced and use of monitoring tools like Sentry, though explicit security headers and published security policies could be improved. Overall, the site is professional, trustworthy, and well-branded, with clear contact information and social media presence. The lack of WHOIS data suggests privacy protection, which is typical for hosting providers. Strategic recommendations include enhancing privacy compliance disclosures and security header implementation to further strengthen trust and compliance.

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 operates in the competitive web hosting and cloud services market, leveraging its parent company IONOS SE's global infrastructure and brand recognition. The business model focuses on subscription-based services including domain registration, shared and dedicated hosting, managed WordPress hosting, and cloud solutions. The company targets a broad customer base from small businesses to enterprises, emphasizing ease of use, scalability, and security. Partnerships and regional sister sites across Europe support localized offerings. The website content and navigation reflect a mature digital presence with integrated marketing tools and analytics, supporting customer acquisition and retention. Growth indicators include continuous product expansion and new server offerings. The company maintains a professional ecosystem with strong branding consistency and trust signals.

Security posture

The website employs HTTPS with a valid SSL certificate, uses security monitoring tools such as Sentry, and integrates client-side security scripts. However, the absence of explicit security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks publicly disclosed security policies or incident response contacts, which are important for transparency and compliance. Privacy and cookie policies are not clearly found in the provided content, indicating a potential compliance gap with GDPR requirements. Overall, the security maturity is good but could be enhanced by publishing security documentation and implementing comprehensive HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add and enforce HTTP security headers such as CSP, HSTS, and X-Frame-Options to strengthen security posture.
  3. Establish and disclose a vulnerability disclosure program and incident response contact information.
  4. Regularly audit and update third-party scripts and tracking tools to minimize security risks.
  5. Enhance transparency by providing detailed business and security certifications on the website.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering and optimized asset loading. It uses web fonts, lazy loading for videos, and preconnect hints to improve performance. The site is mobile-optimized with responsive design and accessibility considerations. JavaScript bundles are modularized and deferred to enhance loading speed. Tracking and marketing scripts such as Sentry, Adobe Target, and Kameleoon are integrated for analytics and A/B testing. The technical infrastructure reflects a mature digital platform with good performance and user experience. Opportunities exist to improve technical SEO and security header implementation to reduce technical debt and enhance resilience.
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.
