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

Groupon International Limited operates www.groupon.com.au as a localized e-commerce platform offering consumers in Australia access to discounted deals, coupons, and services across various categories including local businesses, travel, and goods. The platform leverages a mature technical infrastructure with modern JavaScript frameworks and integrates multiple third-party analytics and security services to ensure performance and fraud prevention. Security posture is strong with HTTPS enforcement, security headers, and CAPTCHA protections, although explicit security policies and incident response contacts are not publicly detailed. Privacy compliance is partially met with a comprehensive privacy policy but lacks a visible cookie consent mechanism. Overall, the website presents a professional and trustworthy front consistent with a large-scale e-commerce business.

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. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

    • 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

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Groupon holds a strong market position as a global leader in deal aggregation and discount offerings, targeting price-conscious consumers seeking value in local and online shopping. The business model centers on connecting merchants with consumers via time-limited offers and coupons, generating revenue through commissions and advertising. The Australian site is part of a broader international network, with partnerships for affiliate marketing and merchant services. The platform's extensive use of analytics and tracking indicates a data-driven approach to customer engagement and marketing optimization.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, modern security headers, and integration of fraud detection services such as Signifyd and Riskified. Use of Google reCAPTCHA v3 helps mitigate automated abuse. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is high but could be improved by publishing formal security documentation and enhancing user-facing privacy controls.

Recommendations

  1. Implement a visible cookie consent banner to comply with privacy regulations and improve user transparency.
  2. Publish a dedicated security policy and incident response information to enhance trust and compliance.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve inclusivity and compliance with standards.
  5. Increase visibility of contact information for security and privacy inquiries to support user trust.

Technical notes

Notes

The site uses a modern tech stack including React (Preact), jQuery, Hogan.js, and Underscore.js, supported by a robust CDN infrastructure. Performance optimizations such as script preloading and lazy loading are implemented. The site is mobile-optimized with responsive design and supports multiple locales. Analytics and marketing tools are extensively integrated, indicating a sophisticated digital marketing strategy. No CMS was explicitly detected, suggesting a custom or proprietary platform. Overall, the technical implementation is solid with room for minor improvements in accessibility and privacy controls.
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.
