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

RSJ is a financial group operating primarily in the Czech Republic with a strong presence in global derivative markets including London, Chicago, New York, Frankfurt, and Tokyo. The company manages a diversified portfolio of investments spanning financial derivatives trading, real estate development, private equity, and emerging sectors such as biotechnology and healthy food production. The website clearly communicates its business scope and warns investors about fraudulent schemes misusing its brand. Technically, the site employs modern web technologies including Google Analytics and Tag Manager, with a cookie consent mechanism supporting GDPR compliance. Security posture is solid with HTTPS enforced, but lacks published security policies or incident response contacts. WHOIS data is missing, which raises concerns about domain registration legitimacy despite the professional website presence. Overall, RSJ presents as a credible financial entity with room for improvement in transparency and security disclosures.

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

6 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 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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

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

RSJ holds a strong market position as a financial group with diversified investments in derivatives trading and real estate. Its business model integrates active market making on major exchanges with portfolio management in private equity and real estate sectors. The company targets investors and institutional clients interested in innovative and future-oriented sectors. The presence of multiple subsidiaries and a foundation indicates a broad operational scope and social responsibility. The website's detailed navigation and content reflect a mature digital presence, supporting investor relations and recruitment. However, the lack of direct contact details and missing WHOIS data suggest areas for enhanced transparency and trust-building.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms in place. The prominent warning about fraudulent use of the RSJ brand indicates awareness of security risks. However, the absence of security headers, published security policies, incident response contacts, or vulnerability disclosure mechanisms limits the security maturity. No vulnerabilities or exposed sensitive data were detected in the content. The missing WHOIS data is a notable risk factor for domain legitimacy. Overall, the security posture is adequate but could be strengthened by formalizing security governance and transparency.

Recommendations

  1. Publish a comprehensive security policy and incident response contact information on the website.
  2. Implement and configure security HTTP headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Clarify domain registration details and ensure WHOIS data is available or justified by privacy protection.
  5. Enhance contact information availability by providing verified company emails and phone numbers for investor and security inquiries.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics, Google Tag Manager, jQuery UI, and Ionicons. The presence of Nette framework scripts suggests a robust backend. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and structured navigation. Hosting provider details are not disclosed. The site uses cookie consent scripts compliant with GDPR. There is no CMS explicitly detected, indicating a custom or framework-based solution. Technical risks include missing security headers and incomplete WHOIS data which may affect trust and domain management.
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.
