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"

    • 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

1blu GmbH holds a solid position in the German hosting market, focusing on professional and business clients. Their competitive advantages include high-performance hosting with NVMe SSDs, managed hosting services, and a comprehensive product portfolio including VPS, root servers, and dedicated servers. Revenue streams likely derive from monthly hosting fees, domain registrations, and business hosting contracts. The target customer segment is SMEs and professionals requiring reliable hosting solutions. The company maintains a partnership ecosystem with affiliate marketing networks such as Belboon and AWIN. Strategic observations suggest a focus on performance and customer support, with transparent pricing and German data center location as trust factors.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and cookie consent is implemented in compliance with GDPR. Forms include CSRF tokens, indicating secure input handling. However, no explicit security policy or incident response information is published, which is a gap in transparency. No security headers were detected in the HTML content, suggesting potential improvements at the server configuration level. No vulnerabilities or exposed sensitive data were found in the content. The absence of a vulnerability disclosure policy or security.txt file limits external security collaboration. Overall, the security posture is adequate but could be enhanced with formal policies and improved header configurations.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts to improve transparency and trust.
  2. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  3. Add a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to meet recognized standards and improve user experience for all users.
  5. Optimize mobile responsiveness and performance to improve engagement and SEO rankings.

Technical notes

Notes

The website uses a modern frontend stack including HTML5, CSS3, JavaScript, jQuery, and Bootstrap framework. The site is hosted in Germany, likely in 1blu's own data center in Frankfurt/Main, ensuring data residency compliance. Performance is moderate with responsive design but could be improved for mobile devices. SEO is well addressed with meta tags and structured navigation. No CMS was detected, indicating a custom or static site approach. Security best practices such as CSRF tokens in forms and HTTPS usage are present, but HTTP security headers are missing in the analyzed content. The site uses affiliate marketing and tracking tools including Google Analytics and Google Adwords, with a clear cookie consent mechanism. Overall, the technical implementation is solid with room for security and accessibility enhancements.
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.
