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

One Family Office is a recently established (2023) multi-family office based in the Czech Republic, offering comprehensive investment management, advisory, asset protection, and concierge services to high-net-worth families and individuals. The company positions itself as the largest family office in Central Europe with a strong team of investment professionals and legal advisors, managing significant assets and family structures. The website is built on WordPress with modern technologies and includes tracking tools such as Google Tag Manager and Facebook Pixel. While the site is professionally designed and content-rich, it lacks explicit privacy and cookie policies, which are critical for GDPR compliance. Security posture is adequate with HTTPS enabled but could be improved by adding security headers and incident response information. Overall, the domain registration is consistent with the business claims and shows 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

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

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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

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

The company targets wealthy families and individuals with assets typically above 10 million USD, providing a multi-pillar service model including investment, advisory, and concierge services. It leverages partnerships with a leading Czech law firm and operates in multiple international locations. The business model focuses on long-term wealth preservation and growth with a diversified global portfolio. The website reflects a mature digital presence but lacks some compliance and security transparency elements. The partnership ecosystem includes legal and financial advisors, and the company actively manages a large volume of family trusts and foundations, indicating a strong market position in Central Europe.

Security posture

The website uses HTTPS and modern tracking technologies but lacks visible security headers and formal security policies. No incident response or vulnerability disclosure information is provided, which limits transparency and preparedness perception. No exposed sensitive data or vulnerable libraries were detected in the provided content. The security score is moderate, with recommendations to implement security headers, privacy and cookie policies, and incident response details to enhance trust and compliance.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a cookie consent mechanism to comply with EU regulations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide incident response and vulnerability disclosure information, including security contact emails.
  5. Regularly audit and update third-party plugins and scripts to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress using the Astra theme and Elementor page builder, supported by several plugins including WP Download Manager and Qi Addons for Elementor. It uses Google Tag Manager and Facebook Pixel for analytics and marketing. The site is mobile-optimized with good SEO meta tags and structured data in JSON-LD format. Performance is moderate, with room for improvement in accessibility and security headers. Hosting provider details are not explicit. The technical stack is modern and suitable for the business needs but requires enhancements in security and privacy compliance.
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.
