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

3 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 19 days

      What to do: Renew domain registration before expiration

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 targets a broad market segment including individuals, small businesses, and enterprises seeking web hosting and cloud infrastructure solutions. Their business model is subscription-based, offering scalable hosting and cloud services. The company benefits from a strong parent entity, IONOS SE, and maintains sister sites in multiple countries, indicating a well-established international presence. Their competitive advantage lies in comprehensive service offerings, strong brand recognition, and integration of AI tools for domain name generation and reputation management. The presence of marketing tools and SEO services further supports customer acquisition and retention. The company’s growth is supported by continuous technology adoption and regional market expansion.

Security posture

The website demonstrates a good security posture with enforced HTTPS, modern security headers, and no visible exposure of sensitive data. Use of third-party security and monitoring tools like Sentry enhances incident detection capabilities. However, the absence of a publicly available security policy or vulnerability disclosure program limits transparency. No incident response contact information is provided, which could be improved to enhance trust and readiness. The site uses multiple tracking and marketing scripts, which are common but require ongoing review to avoid introducing vulnerabilities. Overall, the security maturity is solid but could benefit from enhanced transparency and formalized security communications.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js, which supports server-side rendering and fast page loads. The use of web fonts, optimized images, and preloading techniques indicates attention to performance. The site is mobile-optimized with responsive design and good navigation clarity. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD data. Hosting appears to be managed by IONOS itself, ensuring control over infrastructure. The site uses multiple asynchronous scripts for analytics, A/B testing, and marketing, which are well integrated but require monitoring for performance impact. Overall, the technical implementation is robust, modern, and aligned 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.
