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

Domain.com.au is a leading Australian real estate platform offering comprehensive property listings for sale and rent, real estate agent directories, auction results, and market news. The website targets Australian property buyers, renters, and owners, providing a robust online marketplace and valuable property insights. The platform is well-established with a large user base and strong market presence in the Australian real estate sector. Technically, the website employs modern web technologies including React, Google Analytics, and various advertising and tracking tools, ensuring a responsive and user-friendly experience across devices. Security posture is strong with HTTPS enforcement, reCAPTCHA Enterprise integration, and privacy policies in place, although explicit security headers should be verified. Overall, the site demonstrates a high level of professionalism, trustworthiness, and compliance with privacy regulations. The WHOIS data is privacy protected, which is typical for commercial entities, and does not raise immediate concerns. Strategic recommendations include enhancing security header implementation, establishing a public vulnerability disclosure policy, and continuous monitoring of third-party scripts for vulnerabilities.

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

2 findings rated critical or high. Fix these first.

  1. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

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
  • 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

Domain Holdings Australia operates Domain.com.au as a major real estate portal in Australia, competing with other property listing services. The business model centers on providing property listings, market data, and advertising opportunities for real estate agents and developers. Revenue streams likely include advertising, premium listings, and partnerships. The platform serves a broad audience including home buyers, renters, and property owners, supported by a network of related sites such as Allhomes and Commercial Real Estate. The company leverages strong brand recognition and digital marketing tools to maintain market leadership. Growth indicators include extensive property data, new developments promotion, and integration with digital magazines and news outlets. The partnership ecosystem includes major Australian news media and real estate services, enhancing reach and credibility.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, use of reCAPTCHA Enterprise to mitigate automated abuse, and clear privacy and cookie policies indicating GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not explicitly found in the provided data and should be confirmed. The absence of a public vulnerability disclosure or incident response contact is a gap in security transparency. Overall, the platform demonstrates good security hygiene appropriate for a high-traffic commercial website but could improve by formalizing vulnerability reporting and enhancing header configurations.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Establish a public vulnerability disclosure policy and incident response contact to improve security transparency.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance user privacy controls and clearly communicate data retention policies.
  5. Maintain and improve mobile optimization and accessibility to ensure broad user reach and compliance.

Technical notes

Notes

The website is built using modern web technologies including React and employs multiple third-party services such as Google Analytics, Google Tag Manager, Branch.io, Amazon Ads, and Raygun for analytics, marketing, and error tracking. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with use of content delivery networks and asynchronous script loading to improve load times. The presence of structured data and meta tags supports SEO efforts. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not explicitly available but likely involve enterprise-grade infrastructure given the scale and traffic. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring.
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.
