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

J&T INVESTIČNÍ SPOLEČNOST, a.s. operates a professional investment portal focused on providing detailed information about various 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 wide range of fund products including bonds, equities, private equity, and mixed assets. The website features comprehensive fund data, investor guidance tools, and educational content to assist users in making informed investment decisions. Technically, the website employs modern web technologies including JavaScript, SVG graphics, and CSS with frameworks such as Nette and Swiper for interactive components. The site is mobile-optimized, accessible, and SEO-friendly, providing a smooth user experience. Analytics and marketing tools like Google Analytics, Google Tag Manager, and Mautic are integrated for data collection and user engagement. From a security perspective, the site enforces HTTPS and uses secure forms with validation. However, it lacks explicit security headers and a published security policy or incident response contact, which are recommended for enhanced trust and compliance. The absence of WHOIS data for the domain is a notable gap, slightly impacting the overall trust score. Overall, the website demonstrates a strong business presence with professional design and content quality, good privacy compliance, and a solid technical foundation. Strategic improvements in security transparency and domain registration verification would further strengthen its security posture and credibility.

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.

Business context

Business profile

J&T INVESTIČNÍ SPOLEČNOST, a.s. holds a significant market position in the Czech investment sector, managing assets exceeding 150 billion CZK and operating for over 27 years. The company targets both retail and qualified investors, offering unique and well-rated investment products. Revenue streams likely include management fees from various funds and advisory services. The firm maintains partnerships with J&T Bank and related entities, enhancing its ecosystem. The website reflects a mature digital presence with clear branding, comprehensive fund data, and investor education, supporting customer acquisition and retention. Growth indicators include active content updates, newsletter subscriptions, and social media engagement. The company’s strategic focus on trust, security, and transparency is evident but could be improved with better WHOIS data availability and explicit security policies.

Security posture

The website exhibits a moderate to high security maturity level with HTTPS enforced and secure form handling. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Privacy and cookie compliance mechanisms are implemented effectively. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. There is no visible security policy or incident response contact, which limits transparency and readiness for security incidents. The lack of a security.txt file further reduces vulnerability disclosure facilitation. Compliance with GDPR is supported by a comprehensive privacy policy and cookie consent banner. Overall, the security posture is solid but can be enhanced by adopting recommended security headers, publishing incident response information, and improving domain registration transparency.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact information to improve transparency and readiness.
  3. Create and host a security.txt file to facilitate responsible vulnerability disclosure.
  4. Verify and update WHOIS domain registration data to improve trust and legitimacy perception.
  5. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using modern web standards with a clean HTML5 structure, CSS styling, and JavaScript for interactivity. It leverages the Nette PHP framework evidenced by included scripts, and uses Swiper for sliders. The site loads asynchronously many JavaScript components to optimize performance. Images are served responsively with WebP support for better loading times. The site is mobile-optimized and accessible with semantic markup and ARIA roles. SEO is supported by proper meta tags including Open Graph and Twitter cards. Hosting details are not explicitly found, but the presence of siteone.cz domains for image and script hosting suggests a CDN or specialized hosting provider. Performance is moderate with room for improvement in caching and script optimization. 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.
