Low risk. 2 critical or high findings in Security headers and GDPR outside view.

Security score

79/100

Risk levelLow

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

SchlundTech is a medium-sized European technology provider specializing in domain registration, encryption products, and cloud server hosting. The company, founded in 1995 and part of the 1&1 group, offers a comprehensive Control Center platform for managing domains, encryption certificates, and cloud infrastructure. The website is professionally designed, mobile-optimized, and provides clear navigation and relevant business content targeting entrepreneurs and professional users. Technically, the site uses TYPO3 CMS, integrates Google Tag Manager and Usercentrics for consent management, and employs HTTPS with good security practices. However, the WHOIS data for the domain is missing or not publicly available, which raises concerns about domain registration legitimacy despite the strong business presence and branding. Privacy policies and cookie consent mechanisms are well implemented, indicating GDPR compliance. Overall, the website demonstrates a mature digital presence with a strong security posture but requires verification of domain registration details to fully confirm legitimacy.

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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

SchlundTech holds a solid market position as a domain and hosting provider with over 15,000 customers and 350,000 managed domains. Its business model focuses on providing scalable cloud servers, a wide range of domain TLDs, and encryption solutions, appealing to business customers needing reliable online infrastructure. The company benefits from its affiliation with the 1&1 group, enhancing trust and operational scale. Partnerships with major certificate authorities and registries like Verisign and DENIC further strengthen its ecosystem. The website content and offerings reflect a focus on professional users and enterprises requiring secure and flexible domain and hosting services. Growth indicators include continuous product expansion and a modernized Control Center interface launched recently.

Security posture

The website enforces HTTPS and integrates security best practices such as consent management and asynchronous loading of tracking scripts. Security headers are implied but not explicitly confirmed in the HTML. No vulnerabilities or exposed sensitive data were detected in the content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms limits transparency. The missing WHOIS data for the domain is a notable risk factor, potentially indicating privacy protection or registration issues. Overall, the security posture is strong from a web application perspective but could be improved with clearer security governance disclosures and domain registration transparency.

Recommendations

  1. Verify and publish accurate WHOIS domain registration data to improve trust and legitimacy.
  2. Add a dedicated security policy page and provide incident response contact information.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Explicitly confirm and enforce security headers such as Content-Security-Policy and X-Frame-Options.
  5. Enhance transparency on data retention and privacy practices beyond cookie consent.

Key observations

  1. Website is fully accessible with rich content and professional design.
  2. No WAF or blocking mechanisms detected.
  3. Strong focus on domain registration, encryption products, and cloud server services.
  4. Clear GDPR compliance with privacy and cookie policies and consent management.
  5. No direct contact emails or phone numbers found in the HTML; contact likely via contact form or legal pages.
  6. Use of modern CMS TYPO3 and integration of Google Tag Manager and Usercentrics.
  7. WHOIS data missing or domain not found, which is unusual and requires further investigation.
Technical notes

Notes

The website is built on TYPO3 CMS, a mature and secure content management system. It uses modern JavaScript libraries and integrates Google Tag Manager and Usercentrics for analytics and consent management. The site is mobile-optimized with responsive design and good accessibility features. Performance appears fast with optimized assets and asynchronous script loading. The hosting environment is likely provided by 1&1 IONOS, consistent with the parent company branding. Technical risks are minimal, but the lack of explicit security headers and domain registration transparency are areas for improvement. The site architecture supports scalability and ease of management for complex domain and hosting portfolios.
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.
