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

Skinflint.co.uk is a UK-based price comparison website established in 2008, offering consumers a platform to compare prices across various merchants. The site aggregates product offers and provides ratings to assist users in making informed purchasing decisions. The business operates primarily in the e-commerce sector, targeting UK consumers seeking value and price transparency. Technically, the website employs modern JavaScript modules, uses a custom or proprietary CMS, and integrates cookie consent management and analytics tools such as Matomo. The site is mobile-optimized and demonstrates good SEO and accessibility practices. Security-wise, the site enforces HTTPS and uses cookie consent but lacks explicit security headers and published security policies, which could be improved. Overall, the website is trustworthy with a consistent domain registration history and no signs of blocking or WAF interference.

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.

    • 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

  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 SSL Key Length

      SSL certificate uses 384-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 company operates a niche price comparison service in the UK market, leveraging affiliate marketing models to generate revenue. Its long domain age and consistent registration data support its legitimacy. The business model focuses on aggregating merchant offers and providing consumers with price transparency. The lack of explicit contact information and privacy policies may limit user trust and regulatory compliance. The website's integration with Google DoubleClick and Matomo indicates active monetization and user behavior tracking. Growth opportunities include expanding transparency, adding comprehensive privacy and security policies, and enhancing user engagement through clearer contact channels.

Security posture

The website demonstrates a basic to moderate security posture with HTTPS enabled and cookie consent implemented. However, it lacks visible security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy, which are recommended best practices. No vulnerability disclosure or incident response contacts are published, which could hinder timely reporting and resolution of security issues. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site would benefit from publishing a security policy, implementing additional HTTP security headers, and establishing clear incident response channels to improve its security maturity and compliance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  3. Add explicit contact information including support emails and phone numbers to enhance business credibility.
  4. Establish and publish a security policy and incident response contact information to facilitate vulnerability reporting.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern JavaScript module system with scripts loaded from a dedicated CDN (gzhls.at). It integrates cookie consent management via OneTrust and analytics via Matomo, indicating a mature approach to user privacy and tracking. The site is mobile-optimized and uses semantic HTML with accessibility considerations. Performance appears moderate with asynchronous script loading. The CMS is custom or proprietary, with no common CMS signatures detected. Hosting provider details are not explicit but likely involve CDN and custom hosting. Technical risks include the absence of some security headers and lack of visible vulnerability disclosure mechanisms.
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.
