Cardio Tennis is a fitness and tennis program targeting people of all ages and abilities, operating under the auspices of Tennis Australia. The website serves as a promotional and informational platform to encourage participation in Cardio Tennis activities, provide access to court hire, and promote free trial opportunities. The site is well-branded and consistent with the parent organization's identity, leveraging social media and official Tennis Australia resources to build trust and engagement. Technically, the site is built on WordPress with modern SEO and analytics tools, providing a good user experience with mobile optimization and clear navigation.

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

4 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.

    • 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. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: domain.not.configured

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

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 website positions Cardio Tennis as a niche fitness offering within the broader tennis community in Australia, leveraging the strong brand and infrastructure of Tennis Australia. The business model focuses on community engagement and program promotion rather than direct sales. The site facilitates user interaction through search forms for local programs and court hire, indicating a service-oriented approach. The presence of official social media channels and Tennis Australia links enhances credibility and market reach. The site likely benefits from Tennis Australia's reputation and resources, positioning it well within the sports and fitness sector in Australia.

Security posture

The website demonstrates a moderate security maturity level with enforced HTTPS and use of secure external scripts. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could be exploited in certain attack scenarios. No vulnerability disclosure or incident response contacts are provided, limiting transparency and readiness for security incidents. The site does not implement a cookie consent mechanism, which may pose compliance risks in some jurisdictions. Overall, while no critical vulnerabilities are evident, there is room for improvement in security best practices and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a security.txt file and publicly accessible vulnerability disclosure policy to improve transparency and incident response readiness.
  3. Introduce a cookie consent banner/mechanism to comply with privacy regulations and inform users about tracking.
  4. Provide explicit contact information for security incidents or data protection officer to strengthen trust and compliance.
  5. Enhance accessibility features to improve inclusivity and meet WCAG standards.

Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO plugin, leveraging modern JavaScript libraries such as jQuery and MediaElement.js for video playback. It integrates Google Tag Manager, Google Analytics, and Facebook Pixel for analytics and marketing. The site uses responsive design techniques and serves optimized images for different screen sizes, indicating good mobile optimization. Performance is moderate, with minified CSS and JavaScript assets served via caching. The site lacks advanced security headers and explicit hosting provider information. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and performance tuning.
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.
