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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The PC Optimum program holds a leading position in the Canadian retail loyalty market, leveraging partnerships with subsidiaries such as Shoppers Drug Mart and Pharmaprix, and financial services through PC Financial. Its business model focuses on personalized rewards to drive customer loyalty and increased spending. The program benefits from strong brand recognition, extensive retail footprint, and integration with financial products. The website's content and external links reflect a well-established ecosystem with strategic partnerships and a focus on customer engagement through personalized offers and mobile app accessibility.

Security posture

The website exhibits a high level of security maturity, including HTTPS enforcement, comprehensive security headers, and privacy compliance via OneTrust cookie consent. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of publicly visible incident response or security contact information could be improved to enhance transparency and readiness. The use of multiple third-party scripts necessitates ongoing monitoring to mitigate supply chain risks. Overall, the security posture supports the trustworthiness of the platform and protects user data effectively.

Recommendations

  1. Enhance visibility of incident response and security contact information to improve transparency.
  2. Implement Subresource Integrity (SRI) for all third-party scripts to prevent supply chain attacks.
  3. Regularly audit and update third-party libraries and dependencies to mitigate vulnerabilities.
  4. Deploy Content Security Policy (CSP) reporting to monitor and respond to policy violations.
  5. Continue to strengthen privacy compliance and user consent mechanisms in line with evolving regulations.

Technical notes

Notes

The website is built on a modern React framework with integration of Contentful CMS, Google Maps API, and various marketing and analytics tools such as Google Tag Manager and Facebook Pixel. The presence of Zuora Payments and Ada Chatbot indicates advanced e-commerce and customer support capabilities. Performance is moderate with good mobile optimization and accessibility features. The site uses standard web fonts and preloads resources for improved loading times. Technical debt appears minimal, but continuous monitoring of third-party scripts and dependencies is recommended to maintain security and performance.
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.
