75/100

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

J&T INVESTIČNÍ SPOLEČNOST, a.s. operates a professional investment portal focused on providing information about investment funds available to retail and qualified investors in the Czech Republic. The company positions itself as one of the largest and most respected investment firms in the domestic market, offering a range of investment products including bonds, equities, private equity, and mixed asset funds. The website features comprehensive fund data, investment guides, calculators, and expert contacts, targeting investors seeking reliable and diverse investment opportunities. Technically, the website employs modern web technologies including JavaScript frameworks, SVG graphics, and CSS for a responsive and accessible user experience. The backend likely uses the Nette PHP framework, supported by AJAX and form validation libraries. Performance is moderate with good mobile optimization and SEO practices. The site integrates Google Analytics and Tag Manager for user tracking and marketing insights, alongside a cookie consent mechanism ensuring compliance with privacy regulations. From a security perspective, the site enforces HTTPS and employs nonce attributes in scripts to mitigate injection risks. Cookie consent and privacy policies are clearly presented, indicating GDPR compliance. However, explicit security headers like X-Frame-Options and incident response policies are not evident. The absence of WHOIS data for the domain reduces trust from a domain registration standpoint, though the website content and business presence suggest legitimacy. Overall, the site demonstrates a mature digital presence with strong content quality and user experience, suitable for its financial services audience. The main risk lies in the lack of publicly available domain registration data, which should be addressed to enhance trustworthiness. Strategic recommendations include enhancing security header implementation, publishing incident response and security policies, and verifying domain registration details.

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.

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

  • Security headers: did not complete in this scan.
  • 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

Business profile

J&T INVESTIČNÍ SPOLEČNOST, a.s. holds a strong market position in the Czech investment sector, managing assets exceeding 150 billion CZK and operating for over 27 years. Their business model focuses on offering a broad portfolio of investment funds tailored to both retail and qualified investors, supported by expert advisory and educational resources. Revenue streams likely derive from fund management fees and advisory services. The company maintains partnerships within the J&T financial group, including J&T Banka and related foundations, enhancing its ecosystem and client reach. Growth indicators include active content updates, investment calculators, and a newsletter subscription base. The firm leverages digital marketing and analytics tools to optimize customer engagement and retention.

Security posture

The website exhibits a solid security posture with mandatory HTTPS encryption and use of nonce attributes in inline scripts to prevent cross-site scripting attacks. Cookie consent is implemented via a recognized third-party script, supporting privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as X-Frame-Options and Content-Security-Policy reduces defense-in-depth. There is no visible incident response or security policy documentation, which could impact preparedness and transparency. The lack of WHOIS data for the domain is a notable concern, potentially indicating privacy protection or registration issues. Overall, the security maturity is good but could be improved by publishing security policies and enhancing HTTP headers.

Recommendations

  1. Publish explicit security headers including X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy to strengthen browser security.
  2. Provide publicly accessible incident response and security policy documents to improve transparency and preparedness.
  3. Verify and publish domain registration details to enhance trust and legitimacy perception.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance data retention and privacy policy disclosures to align with best GDPR practices.

Notes

The website is built using modern front-end technologies including JavaScript, CSS, and SVG graphics, ensuring a responsive and visually appealing user interface. The backend likely uses the Nette PHP framework, supported by AJAX and form validation libraries, enabling dynamic content and interactive features such as investment calculators and search functionality. Performance is moderate with asynchronous script loading and optimized images. Mobile optimization is good, with adaptive images and responsive layouts. SEO is well addressed through meta tags, Open Graph, and Twitter card metadata. Accessibility features appear adequate, though further testing is recommended. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional and user-friendly investment portal.
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.
