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

PriceRunner UK operates as a leading online price comparison platform, enabling UK consumers to search and compare prices across millions of products from thousands of British stores. The website is professionally designed, mobile-optimized, and integrates modern web technologies such as React and Google Tag Manager, reflecting a mature digital infrastructure. Security posture is strong with HTTPS enforced and no visible vulnerabilities, complemented by comprehensive privacy and cookie policies that align with GDPR requirements. However, the absence of publicly available WHOIS data limits domain registration transparency, though the association with Klarna, a reputable financial technology company, enhances trustworthiness. Overall, PriceRunner UK presents a secure, user-friendly, and credible e-commerce service with room for minor improvements in explicit security header disclosures and contact information visibility.

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

7 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"

    • 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

PriceRunner UK holds a significant market position in the UK e-commerce sector as a price comparison service, targeting consumers seeking savings and product deals. Its business model revolves around aggregating product pricing data and facilitating informed purchasing decisions. The platform benefits from Klarna's backing, leveraging its CDN and brand recognition. The website's content and structure indicate a focus on user engagement through popular product showcases and category navigation. Advertising and analytics integrations suggest a balanced approach to monetization and user experience. The lack of direct contact details on the homepage may reflect a digital-first customer support strategy.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, absence of exposed sensitive data, and use of secure forms. While explicit security headers like Content-Security-Policy and X-Frame-Options are not directly observable in the HTML, the overall configuration suggests adherence to best practices. The presence of third-party scripts such as Google Analytics and FullStory is managed with standard consent mechanisms. No critical vulnerabilities or compliance gaps were detected, indicating readiness for GDPR and general data protection standards. Incident response and security policy documentation are not publicly evident, which could be areas for enhancement.

Recommendations

  1. Implement and explicitly declare security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish clear incident response and security policy documentation accessible to users and partners.
  3. Enhance visibility of contact information, including dedicated security and support emails, to improve trust and compliance.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities and privacy risks.
  5. Develop a vulnerability disclosure program or security.txt file to encourage responsible reporting and transparency.

Technical notes

Notes

The website is built on a modern React framework with efficient use of CSS-in-JS (Emotion) for styling, ensuring responsive and accessible design. Integration with Google Tag Manager and FullStory indicates advanced analytics and user behavior tracking capabilities. The use of Klarna's CDN and asset hosting optimizes performance and reliability. The site loads quickly with preconnect and preload hints for critical resources, enhancing user experience. No CMS is explicitly detected, suggesting a custom or proprietary platform. Technical debt appears minimal, with opportunities to improve explicit security header implementation and expand accessibility features.
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.
