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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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

Chronuu operates in the technology sector focusing on digital estate planning and legacy management. Its business model is subscription-based, targeting individuals who want to securely manage their estate and personal legacy digitally. The company leverages a multi-channel approach including a website, mobile apps on iOS and Android, and active social media engagement. The market position is that of a specialized provider in Germany, with competitive advantages including strong data protection, encrypted storage, and user-centric design. Revenue streams likely include subscription fees for different service tiers. The company is relatively new, founded in 2022, and operates under the legal entity 4toStay GmbH. Partnerships or subsidiaries were not identified. The platform's growth potential is supported by increasing digitalization of personal data and estate management needs.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and data hosted in Germany under strict data protection laws. The provider does not access user data, enhancing privacy. Cookie consent mechanisms are implemented, and Matomo analytics is used for privacy-respecting tracking. However, no explicit security headers (e.g., CSP, HSTS) were detected, and no published security policy or incident response contacts were found. There is no vulnerability disclosure or security.txt file, which could improve transparency and trust. No exposed sensitive data or vulnerable libraries were identified. Overall, the security maturity is good but could be enhanced by adding security headers and formalizing incident response procedures.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and provide dedicated incident response contact channels (e.g., security@ or abuse@ email).
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility compliance to improve usability for all users.
  5. Regularly audit and update third-party plugins and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using popular plugins such as WPBakery Page Builder and Slider Revolution for content management and presentation. The tech stack includes Bootstrap for responsive design and FontAwesome for icons. Matomo analytics is used for privacy-conscious user tracking. Hosting is supported by Cloudflare DNS and nameservers, providing performance and security benefits. The site is mobile-optimized with good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with some potential for optimization. The technical implementation is solid with opportunities to improve security headers and accessibility features.
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.
