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. 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. 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  3. 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 technology sector, focusing on hosting, cloud services, and online marketing. Its business model revolves around providing digital infrastructure and tools to enable businesses to establish and grow their online presence. The company leverages a broad portfolio including shared and dedicated hosting, cloud computing, email solutions, and eCommerce platforms. Partnerships and affiliate programs are actively promoted, enhancing their ecosystem. The presence of personal consultants and 24/7 support indicates a customer-centric approach. The company’s large scale, with millions of domains and customers, positions it as a major player in the hosting and cloud market. Strategic observations include a strong emphasis on AI-powered tools and cloud innovation, aligning with current market trends.

Security posture

The website employs strong security measures including HTTPS with excellent SSL configuration and likely comprehensive security headers. No exposed sensitive data or vulnerable libraries were detected in the provided content. The use of secure forms and validation is evident. However, the absence of explicit security policies, incident response procedures, or vulnerability disclosure mechanisms on the site suggests room for improvement in transparency and readiness. The company’s ISO-certified security claim and award-winning support are positive indicators of a mature security culture. Overall, the security posture is strong but could benefit from enhanced public documentation of security practices and incident handling.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and customer trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear contact channels for security incidents, such as security@ or abuse@ email addresses.
  4. Regularly review and update third-party scripts and tracking tools to minimize potential vulnerabilities.
  5. Enhance visibility of the Data Protection Officer contact information to strengthen GDPR compliance.

Technical notes

Notes

The website is built on a modern technology stack featuring React and Next.js, ensuring fast and responsive user experience. It integrates multiple analytics and marketing technologies including Adobe Analytics, Google Tag Manager, TikTok, Facebook, and LinkedIn pixels, indicating a sophisticated data-driven approach. The site is mobile-optimized with excellent accessibility and SEO practices. Hosting appears to be managed internally or via IONOS infrastructure, supporting high performance and scalability. The use of a custom CMS (TYPO3) suggests a tailored content management approach. Technical risks are minimal, but the extensive use of third-party scripts requires ongoing security vigilance.
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.
