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. 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

  2. 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 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';…

  3. GDPR outside view

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

    • 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

The company holds a strong market position as a specialist retailer with a long history, leveraging partnerships with major payment providers such as PayPal and Amazon Pay. Their integration of Trustpilot reviews and active social media presence enhances customer trust and engagement. The business model includes multiple revenue streams including product sales, installation services, and trade-in programs. The website content and marketing tools indicate a mature digital strategy aimed at consumer electronics enthusiasts in the UK.

Security posture

The website employs HTTPS with good SSL configuration and integrates secure payment SDKs, demonstrating a solid baseline security posture. Use of consent management for cookies and tracking aligns with privacy regulations. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the analysis. The absence of a published security policy or incident response contact suggests room to enhance transparency and incident readiness.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve trust and preparedness.
  3. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.
  4. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.
  5. Continue to maintain and update privacy and cookie policies to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on ASP.NET Web Forms with a modern front-end using Bootstrap and jQuery. It integrates multiple third-party services including Google Tag Manager, PayPal SDK, Amazon Pay SDK, Trustpilot widgets, and live chat via Tawk.to. The site is mobile responsive with good SEO practices and moderate performance. There is no detected CMS, and hosting provider details are not evident. The technical stack is mature but could benefit from modernization and improved accessibility compliance.
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.
