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

Gumtree.com.au is a major Australian classified ads platform facilitating local buying and selling of goods and services. The business operates in the e-commerce sector with a large market presence in Australia. The provided content is a block page indicating temporary suspension of access due to suspicious activity, preventing full content analysis. The technical infrastructure includes use of Google Cloud DNS and JavaScript for dynamic content, but no further technical details are accessible. Security posture cannot be fully assessed due to content blocking; however, WHOIS data indicates a legitimate domain registration with standard domain status protections but lacks DNSSEC. No privacy, cookie, or terms policies are visible, and no contact or security incident response information is provided on the block page. Overall, the site is currently inaccessible for detailed security and compliance evaluation.

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

7 findings rated critical or high. Fix these first.

  1. 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Gumtree.com.au operates as a classified ads marketplace targeting general consumers in Australia. The platform's business model centers on user-generated listings for local transactions. The company likely generates revenue through advertising and premium listing services. The domain registration and DNS setup suggest a professional and stable infrastructure. However, the lack of accessible content limits insights into partnerships, certifications, or detailed business operations. The platform is well-known in its market segment, indicating strong competitive positioning.

Security posture

The security posture assessment is limited due to the block page preventing access to the main site content. No security headers or SSL details were available. The WHOIS data shows domain status codes that prevent unauthorized domain modifications, which is positive. DNSSEC is not enabled, representing a minor security gap. No incident response or vulnerability disclosure information is found. The block page itself is a security measure to prevent abuse, indicating active monitoring of suspicious activity. Overall, the security maturity cannot be fully determined but basic domain protections are in place.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish clear privacy, cookie, and terms of service policies accessible even on block or error pages.
  3. Provide visible contact information including security incident response contacts.
  4. Implement and verify security headers such as Content-Security-Policy and X-Frame-Options.
  5. Ensure SSL/TLS configuration is strong and enforce HTTPS site-wide.
Site observations

Generic detected. The page content indicates access has been temporarily suspended due to suspicious activity, showing a block message with no actual site content accessible. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Key observations

  1. Website content is blocked due to detected suspicious activity from the user network.
  2. No privacy, cookie, or terms of service policies found in the provided HTML content.
  3. No contact information or security policies are visible on the blocked page.
  4. WHOIS data shows domain is registered with a reputable registrar and uses Google DNS services.
  5. No analytics, advertising, or tracking scripts detected in the blocked content.
  6. No forms or data collection mechanisms are present in the blocked page.
  7. No social media or email contact links found in the provided content.
  8. The site uses JavaScript to fetch visitor IP and request ID dynamically on the block page.
  9. No security headers or SSL configuration details available from provided data.
Technical notes

Notes

The website uses JavaScript and Google Cloud DNS services. The block page uses inline styles and scripts to dynamically display IP and request ID information. No CMS or frameworks are detectable from the block page. The site likely uses a modern tech stack but this cannot be confirmed due to content blocking. Performance, SEO, and accessibility cannot be assessed. The domain is registered with GoDaddy.com LLC, a reputable registrar. The lack of DNSSEC and security headers is noted as a technical risk.
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.
