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

Circle K Stores operates a large convenience store and gas station chain primarily in the United States, offering fuel, retail products, and business services such as fleet cards and loyalty programs. The company is a subsidiary of Alimentation Couche-Tard, a major player in the retail and energy sectors. Their website demonstrates a mature digital presence with comprehensive content, clear navigation, and strong branding consistency. The site targets both consumer and business audiences with tailored offerings and regional customer service contacts. Technically, the website is built on Drupal 9 and integrates modern analytics and marketing tools including Google Tag Manager, Hotjar, Cookiebot for consent management, and Qualtrics for feedback. The site is mobile-optimized and accessible, with good SEO practices and performance. Security measures include HTTPS enforcement, multiple security headers, and no visible sensitive data exposure. While the site lacks a dedicated security policy or incident response page, it maintains GDPR compliance with a detailed privacy and cookie policy and a robust consent mechanism. The WHOIS data aligns well with the business claims, reinforcing legitimacy. Overall, the security posture is strong, with recommendations to enhance transparency through a security policy and vulnerability disclosure. The strategic risk is low given the enterprise scale and compliance posture, but continuous monitoring of third-party scripts and enhanced security documentation would further strengthen trust and resilience.

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. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Circle K is positioned as a leading convenience store and fuel retailer with a broad footprint in the US market. Its competitive advantage lies in its extensive network, loyalty programs (Inner Circle), and business fleet card services (Circle K PRO). The business model combines retail sales with value-added services for commercial customers. Revenue streams include fuel sales, convenience retail, and business services. The company leverages partnerships with major ad networks and analytics providers to optimize marketing and customer engagement. Growth indicators include digital payment solutions (Easy Pay) and EV charging services. The partnership ecosystem includes parent company Alimentation Couche-Tard and related domains for franchise and fleet services. Strategic observations highlight a focus on customer experience, data-driven marketing, and regulatory compliance.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a comprehensive set of security headers implemented. Cookie consent is managed via Cookiebot, ensuring GDPR compliance and user control over tracking. No exposed credentials or sensitive data were detected in the HTML content. The use of reputable third-party analytics and marketing tools is balanced with user consent mechanisms. However, the absence of a public security policy or incident response contact limits transparency. No vulnerability disclosure or security.txt file was found, which could be improved to foster responsible reporting. Overall, the site demonstrates good security hygiene appropriate for an enterprise retail website.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement a security.txt file to facilitate vulnerability disclosures.
  4. Regularly audit and update third-party scripts to mitigate supply chain risks.
  5. Enhance Content Security Policy to restrict inline scripts and reduce XSS risks.

Technical notes

Notes

The website is built on Drupal 9, a modern and widely supported CMS, indicating a solid technical foundation. Integration with Google Tag Manager, Hotjar, Cookiebot, and Qualtrics shows advanced digital marketing and user experience capabilities. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with potential for optimization in loading times. The use of multiple analytics and marketing pixels is extensive but managed with user consent. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring. The infrastructure appears stable with no signs of WAF blocking or content restrictions.
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.
