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

SK Meteor Praha is a historic tennis club based in Prague, established in 1884, offering tennis training, competitive teams, court rentals, and community events. The website serves as an informational portal for members and visitors, highlighting club history, services, and contact details. The club targets tennis enthusiasts of all ages, including children, youth, adults, and seniors, positioning itself as a well-established local sports institution. Technically, the website uses legacy technologies such as jQuery 1.4.2 and Google Maps API, with Google Analytics for visitor tracking. However, it lacks modern security features such as HTTPS and security headers, and does not provide privacy or cookie policies, indicating compliance gaps. The security posture is weak due to the absence of SSL and outdated libraries, posing risks to user data confidentiality and integrity. Overall, the site is functional but requires modernization and security improvements to enhance trust and compliance.

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

12 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  4. 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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

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

The club operates as a small, community-focused sports organization with a long tradition in Prague. Its business model revolves around membership fees, tennis court rentals, and organizing tennis events and camps. The presence of local government and sports association partners strengthens its market position and community trust. The website content is relevant and targeted, but the digital presence is basic and could benefit from modernization to improve user experience and broaden reach. The club's partnerships with local authorities and tennis equipment suppliers indicate a stable ecosystem supporting its operations.

Security posture

The website currently lacks HTTPS, exposing users to potential interception risks. The use of an outdated jQuery version may introduce vulnerabilities exploitable by attackers. No security headers are detected, reducing protection against common web attacks. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No incident response or security contact information is provided, limiting the club's ability to handle security incidents effectively. Overall, the security maturity is low, requiring urgent improvements to protect user data and comply with legal requirements.

Recommendations

  1. Implement HTTPS across the entire website with a valid SSL/TLS certificate.
  2. Upgrade all JavaScript libraries, especially jQuery, to current secure versions.
  3. Add and publish comprehensive privacy and cookie policies with user consent mechanisms.
  4. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Establish a security incident response contact and consider publishing a vulnerability disclosure policy.

Technical notes

Notes

The website uses legacy jQuery 1.4.2 and Google Maps API v3 for interactive map features. Google Analytics is implemented via the older ga.js script. The site loads Google Fonts for typography. The hosting is via a Czech hosting provider (cesky-hosting.eu). The HTML structure is basic with some inline styles and scripts. Performance is moderate but could be improved with modern front-end frameworks and optimization. Mobile optimization is basic, with no explicit responsive design detected. Accessibility features are minimal. SEO is basic with meta description and keywords but no structured data or Open Graph tags. Overall, the technical infrastructure is functional but dated and requires modernization to improve security, performance, and user experience.
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.
