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

Groupon International Limited operates www.groupon.com.au as a leading e-commerce platform specializing in discounted deals, coupons, and local experiences for Australian consumers. The website offers a broad range of services including shopping deals, travel bookings, and gift options, targeting a general consumer audience seeking savings and convenience. The platform is well-positioned in the market with consistent branding and a large user base. Technically, the website employs a modern technology stack including React (Preact), Google reCAPTCHA, fraud detection services (Signifyd, Riskified), and performance monitoring tools. The site is optimized for desktop and mobile, with good accessibility and SEO practices. Security measures include HTTPS, anti-fraud scripts, and CAPTCHA integration, although explicit security headers are not visible in the HTML source. The security posture is strong with no visible vulnerabilities or exposed sensitive data. Privacy compliance is basic but includes a comprehensive privacy policy and cookie consent mechanisms. Business credibility is high due to the presence of official social media links, legal policies, and consistent professional content. WHOIS data is limited due to registrar privacy policies but aligns with legitimate domain registration practices for .au domains.

Strategic recommendations include enhancing visible security headers, publishing incident response contacts, and maintaining up-to-date third-party libraries to sustain security and compliance standards.

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's Australian site is part of a global e-commerce network offering discounted deals and vouchers. Its business model relies on partnerships with merchants to provide consumers with savings on goods and services. The platform targets price-conscious consumers and leverages affiliate marketing and advertising networks for revenue. The company maintains a strong partnership ecosystem including affiliate platforms and fraud prevention services. Growth indicators include active promotions, app downloads, and extensive deal offerings. The site’s professional design and comprehensive content support strong market positioning in the Australian e-commerce sector.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, integration of Google reCAPTCHA v3 for bot mitigation, and use of fraud detection services such as Signifyd and Riskified. No exposed sensitive information or vulnerable libraries were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not visible in the source, which could be improved. Privacy policies are comprehensive but GDPR compliance indicators are minimal. Incident response and security contact information are not publicly available, representing a compliance gap. Overall, the site is secure but could enhance transparency and header security.

Recommendations

  1. Implement and explicitly publish security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish clear incident response and security contact information to improve transparency and compliance.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance GDPR compliance indicators and provide clearer user privacy controls.
  5. Maintain and improve mobile optimization and accessibility to sustain excellent user experience.

Technical notes

Notes

The site uses a modern JavaScript framework (Preact) optimized for performance and mobile responsiveness. It leverages multiple third-party scripts for analytics, fraud detection, and advertising, indicating a complex but well-managed technical infrastructure. Performance monitoring is implemented via Boomerang. The site uses Google reCAPTCHA v3 for security and integrates with Google Tag Manager and Optimize Suite for analytics and A/B testing. The presence of multiple CDN domains for assets suggests a distributed hosting approach. No CMS was explicitly detected. Overall, the technical stack is modern, performant, and scalable with minor opportunities for security header improvements.
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.
