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. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: relay1.bt.net

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

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

B&Q's market positioning as a large, established home improvement retailer is supported by its extensive product range and services. The business model combines direct retail with a marketplace for verified sellers, enhancing product variety. Revenue streams include product sales, services like installation and planning appointments, and finance offerings. The target audience includes UK homeowners and DIY enthusiasts. The company benefits from a strong partnership ecosystem and maintains consistent branding and trust signals such as verified sellers and comprehensive customer support.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, secure cookie practices, and integration of third-party security monitoring tools like Dynatrace and TrustArc. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident, representing an area for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The presence of consent mechanisms aligns with GDPR compliance, and forms appear to be standard without visible security flaws. Incident response and security policy pages are not explicitly found, suggesting potential areas to enhance transparency.

Recommendations

  1. Implement explicit Content-Security-Policy and X-Frame-Options headers to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response information to improve transparency and trust.
  3. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  4. Enhance contact information with verified company emails for direct support and security reporting.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and practices.

Technical notes

Notes

The website is built on a modern React framework with extensive use of third-party analytics, marketing, and personalization tools. It uses Bloomreach CMS for content management and integrates multiple APIs for product data, search, and customer services. Performance is moderate with good mobile optimization and accessibility features. The site employs advanced tracking and personalization technologies, indicating a high level of digital maturity. Opportunities exist to improve security headers and streamline third-party script management to reduce technical risk.
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.
