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

Hopae.cz is a website dedicated to the Korean martial art Hopae Sool, providing detailed information about its history, training schedules, events, membership fees, and contact details primarily for the Czech Republic audience. The site targets martial arts enthusiasts and practitioners of all ages, offering training sessions, seminars, and membership management. The business operates as a small martial arts association founded in 2016, with a clear focus on community and education rather than commercial scale operations. Technically, the website employs standard web technologies including JavaScript, Google Analytics, and likely Bootstrap for UI components. The site is mobile responsive with good navigation and content structure, although some accessibility and SEO optimizations could be improved. Performance is moderate, and no CMS or hosting provider details are evident from the content. From a security perspective, the site uses HTTPS but lacks visible security headers and privacy/cookie policies, indicating gaps in compliance and security best practices. No WHOIS data was found, which reduces domain trustworthiness and raises questions about domain registration legitimacy. Contact information is clearly provided, enhancing business credibility. Overall, the site is safe with no adult or malicious content detected. Strategically, the site would benefit from implementing privacy and cookie policies with consent mechanisms, improving security headers, and verifying domain registration details to enhance trust and compliance. These improvements would strengthen the security posture and user trust while maintaining the site's educational and community focus.

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.

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

    • 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

  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.

Business context

Business profile

Hopae.cz occupies a niche market as a martial arts association focused on Hopae Sool in the Czech Republic. Its competitive advantage lies in its authentic connection to Korean grandmasters and a structured training program. Revenue streams include tuition fees, membership dues, seminars, and equipment sales. The target customers are martial arts practitioners of all ages, with a strong local presence. Growth indicators include regular events and expanding training locations. The site maintains partnerships with related martial arts organizations, enhancing its ecosystem. Operationally, the association is small but professional, with transparent communication and clear organizational structure.

Security posture

The website demonstrates a basic security maturity level with HTTPS enabled but lacks critical security headers such as Content Security Policy, HSTS, and X-Frame-Options. No privacy or cookie policies are present, which is a compliance gap under GDPR. The absence of WHOIS data reduces domain trust and may indicate privacy protection or registration issues. No incident response or vulnerability disclosure information is provided. Data protection officer contact is not found. Overall, the security posture is moderate but requires enhancements in policy transparency, header implementation, and domain legitimacy verification to reduce risk and improve compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to comply with GDPR.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Verify and update WHOIS domain registration information to improve domain trustworthiness and transparency.
  4. Establish and publish incident response and vulnerability disclosure policies with clear contact channels.
  5. Improve accessibility features and SEO optimizations to enhance user experience and search visibility.

Technical notes

Notes

The website uses a standard modern tech stack with JavaScript and Google Analytics for tracking. The presence of dropdown menus and classes suggests Bootstrap or similar CSS framework usage. The site is mobile responsive and has a clear navigation structure. Performance is moderate with no major issues detected. However, no CMS or hosting provider information is evident, and no advanced frameworks are detected. The site could benefit from enhanced accessibility features and SEO improvements. Security-related technical debt includes missing security headers and lack of privacy/cookie compliance mechanisms.
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.
