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

Walmart.com is the official online retail platform of Walmart, a leading global retailer and e-commerce enterprise. The website offers a wide range of products including groceries, apparel, electronics, and home goods, supported by services such as in-store pickup, delivery, and the Walmart+ subscription. The site targets general consumers seeking everyday low prices and convenience. Technically, the site is built on modern frameworks like React and Next.js, leveraging multiple CDNs and third-party services for performance and marketing. Security posture is strong with HTTPS, comprehensive Content Security Policy, and bot protection. However, explicit privacy and cookie policies were not detected in the provided content, which is a compliance gap. WHOIS data is unavailable or blocked, but the website's branding and technical indicators confirm legitimacy. Overall, Walmart.com demonstrates a mature digital presence with excellent user experience and security, though privacy transparency could be improved.

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

3 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

    • 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

Walmart holds a dominant position in retail and e-commerce markets, leveraging its extensive physical store network and online platform. The business model combines direct sales with marketplace offerings, supported by subscription services like Walmart+. Revenue streams include product sales, memberships, and advertising partnerships. The target audience is broad, encompassing general consumers across the United States. Walmart's partnership ecosystem includes major technology and advertising providers such as Accenture, Google, and DoubleClick. The website's content and marketing focus on seasonal promotions, new arrivals, and exclusive brands, indicating strategic merchandising and customer engagement. The company operates at an enterprise scale with consistent branding and strong trust signals.

Security posture

The website employs robust security measures including HTTPS encryption, strict Content Security Policy headers, and bot mitigation via PerimeterX. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Security best practices are evident in script sourcing and resource loading policies. However, the absence of publicly accessible security policies, incident response contacts, or vulnerability disclosure mechanisms limits transparency. Compliance with GDPR and other privacy regulations is not clearly demonstrated in the content. Incident response readiness and data protection officer information are not found, suggesting areas for improvement in security governance and communication.

Recommendations

  1. Publish comprehensive privacy and cookie policies prominently linked on the homepage.
  2. Provide clear contact information for security incidents and establish a vulnerability disclosure program.
  3. Enhance GDPR compliance transparency by including data protection officer contact details and user rights information.
  4. Regularly audit and minimize third-party scripts to reduce attack surface and improve privacy.
  5. Maintain and update WHOIS records to ensure domain registration transparency and trust.

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.
