Groupon · E-commerce · Belgium

Low risk. 2 critical or high findings in Security headers and SSL/TLS.

Security score

80/100

Risk levelLow

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

Groupon Belgium operates as a localized e-commerce platform offering consumers discounted deals on a variety of services including dining, beauty, travel, and shopping. The website is well-branded and consistent with the global Groupon identity, targeting Belgian consumers primarily in French and Dutch. The platform leverages modern web technologies and integrates advanced fraud detection and bot prevention services to secure transactions and user interactions. Privacy and cookie policies are comprehensive and GDPR compliant, reflecting a mature approach to data protection. However, explicit security policies and incident response contacts are not publicly available, which could be improved to enhance trust and transparency.

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. 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. 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 Belgium holds a strong market position as a leading deal aggregator in the region, benefiting from the global Groupon brand. Its business model focuses on connecting consumers with local merchants through discounted vouchers and experiences. The platform supports multiple languages and regional targeting, indicating a tailored approach to the Belgian market. Partnerships with fraud detection services like Signifyd and Riskified enhance transaction security. The absence of direct contact information on the homepage suggests a focus on digital self-service and automated support channels.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, modern security headers, and integration of anti-fraud and bot mitigation technologies. The use of Google reCAPTCHA and third-party fraud services indicates proactive risk management. However, the lack of publicly available security policies, incident response procedures, and vulnerability disclosure programs represents a gap in transparency and readiness communication. No critical vulnerabilities or exposed sensitive data were detected in the analysis.

Recommendations

  1. Publish a dedicated security policy and incident response contact information to improve transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance contact options for security and privacy concerns to build user trust.
  4. Regularly review and update privacy and cookie policies to maintain GDPR compliance.
  5. Continue leveraging advanced fraud detection and bot prevention technologies to mitigate emerging threats.

Technical notes

Notes

The website uses a modern tech stack including React/Preact for frontend rendering, with extensive use of JavaScript libraries such as Hogan.js and Underscore.js. Performance optimizations include preloading fonts and scripts, lazy loading images, and CDN usage for static assets. The site is mobile-optimized and accessible, with proper meta tags for SEO. Integration with Google Analytics and Tag Manager supports robust analytics and marketing efforts. Hosting details are not explicitly identified but the use of multiple Groupon CDN domains suggests a distributed content delivery infrastructure.
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.
