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. 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

      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: Twitter, LinkedIn

      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

J&T BANKA operates in the competitive private banking and investment sector, targeting high-net-worth individuals and corporate clients. Its competitive advantage lies in offering tailored financial products, including proprietary investment funds and unique vehicles not commonly available in the market. The bank's business model combines wealth management, project financing, and family office services, supported by a strong brand and digital presence. Revenue streams likely include fees from asset management, financing services, and advisory. The company maintains partnerships with various asset managers and investment firms, enhancing its product offerings. Growth indicators include active content marketing via podcasts and media, and a consistent brand image. The bank's operations are primarily Czech-focused but with European investment reach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive information. Privacy policies and cookie consent mechanisms align with GDPR requirements. The presence of a whistleblowing channel and a named compliance officer indicates readiness for incident response and regulatory compliance. No security.txt or explicit vulnerability disclosure policy was found, representing an area for improvement. Third-party scripts are limited and primarily for analytics, reducing attack surface. Overall, the security maturity is high with minor gaps in transparency and formal vulnerability disclosure.

Recommendations

  1. Publish a dedicated terms of service page to clarify user agreements and legal terms.
  2. Implement and publicly link a security.txt file to facilitate responsible vulnerability disclosure.
  3. Enhance transparency on data retention policies and user data handling practices.
  4. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.
  5. Maintain and promote the whistleblowing channel and compliance contacts to strengthen security culture.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js, ensuring server-side rendering and good performance. Kentico Kontent CMS is used for content management, enabling modular and dynamic content delivery. The site loads multiple CSS chunks and JavaScript asynchronously, optimizing load times. Mobile optimization and accessibility are well addressed. Analytics are implemented via Piwik PRO, a privacy-focused platform. No major technical debt or outdated technologies were detected. Hosting provider details are not explicit but the infrastructure supports a performant and secure user experience. Opportunities exist to further improve SEO and accessibility with enhanced metadata and ARIA attributes.
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.
