49/100

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

The website memberzone.cz is a newly registered membership portal focused on fitness and wellness services, including activities such as badminton, massages, personal training, and group classes like Zumba. The site is built using ASP.NET Web Forms technology and hosted likely by Webglobe, as indicated by the registrar and name servers. The content is basic and primarily serves as a login and navigation portal for members. There is no evidence of privacy or cookie policies, nor terms of service, which limits compliance and trustworthiness. The site lacks contact information and modern web features such as mobile optimization and accessibility enhancements. Security posture is weak, with no visible HTTPS confirmation or security headers, and some client-side JavaScript errors are present.

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

5 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

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 · found on this site
  • 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

The business appears to be a small-scale fitness or wellness club targeting local members in the Czech Republic. The business model is membership-based, offering various sports and wellness services. The domain age is consistent with a recently launched service. There are no visible partnerships or certifications, and the site lacks marketing or analytics tools, suggesting a limited digital marketing strategy. The absence of contact details and policies may hinder customer trust and regulatory compliance. Growth potential may depend on improving digital presence and security.

Security posture

The security maturity of the website is low. There is no indication of HTTPS usage or security headers, which are critical for protecting user data, especially on login forms. The presence of JavaScript errors and lack of CSRF or input validation mechanisms increase risk. No incident response or vulnerability disclosure information is provided. The site does not demonstrate GDPR compliance or data protection officer contact information. Overall, the site is vulnerable to common web security issues and lacks transparency in security practices.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all communications.
  2. Add and publicly display privacy and cookie policies to comply with GDPR and build user trust.
  3. Include clear contact information such as support emails and phone numbers for user assistance and incident reporting.
  4. Fix JavaScript errors and enhance client-side and server-side input validation to prevent vulnerabilities.
  5. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) and implement CSRF protection.

Technical notes

Notes

The website uses ASP.NET Web Forms technology, which is somewhat dated compared to modern SPA frameworks. The HTML structure is basic with inline styles and absolute positioning, which may hinder responsive design and accessibility. There is no evidence of a CMS or modern JavaScript frameworks. The site lacks SEO meta tags and structured data, limiting search engine visibility. Performance is likely moderate but could be improved with modern front-end practices. Hosting appears to be with Webglobe, a known provider. Technical debt is present due to outdated practices and missing modern web standards.
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.
