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"

    • 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. 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

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 primarily in the UK market targeting consumers looking to save money on essential services. Its business model relies on affiliate partnerships and lead generation across multiple sectors including energy, telecommunications, insurance, and finance. Uswitch maintains a competitive advantage through exclusive deals, extensive provider listings, and consumer trust signals such as high Trustpilot ratings. The ecosystem includes partnerships with major UK providers and review platforms, supporting its market leadership and growth potential.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a robust cookie consent mechanism supporting GDPR compliance. Third-party scripts are managed efficiently using Partytown to reduce risk. However, the absence of a publicly available security policy, incident response contacts, and vulnerability disclosure information indicates room for improvement in transparency and incident readiness. No critical vulnerabilities or exposed sensitive data were detected in the analysis.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency and user trust.
  2. Implement and publicize a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  3. Enhance accessibility features to meet higher standards and improve inclusivity.
  4. Regularly audit and update third-party scripts to mitigate potential security risks.
  5. Provide clear contact information for security and privacy inquiries to improve compliance and user confidence.

Technical notes

Notes

Uswitch employs a modern technology stack including the Qwik framework and React components, leveraging Partytown for third-party script isolation and asynchronous loading. The site uses Google Tag Manager, Facebook and TikTok pixels, and proprietary analytics (Nerdalytics) for marketing and user behavior tracking. Performance is optimized with service workers and preloading strategies, resulting in fast load times and excellent mobile responsiveness. SEO and accessibility are well addressed, though some enhancements could further improve compliance and user experience.
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.
