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

4 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 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

  3. 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

Halifax operates in the UK finance sector as a major retail bank under Lloyds Banking Group. Its business model focuses on providing a broad spectrum of financial products to individuals, including everyday banking, borrowing, mortgages, and investment services. The company benefits from strong brand recognition and a large employee base (~60,000). The website supports customer engagement through detailed product information, calculators, and support resources. The presence of sister domains and partner sites under Lloyds Banking Group indicates a robust partnership ecosystem. The company targets a wide demographic of UK residents seeking banking and financial services, with growth potential in digital banking channels. Strategic observations include leveraging digital marketing and analytics extensively, maintaining strong compliance and security standards, and providing accessible customer support.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive Content Security Policy, and likely other standard security headers such as X-Frame-Options and X-Content-Type-Options. There is no evidence of exposed sensitive information or vulnerable libraries. The use of third-party security and monitoring tools like LivePerson and Boomerang indicates active performance and security monitoring. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, the absence of a publicly visible vulnerability disclosure program or incident response contact details suggests room for improvement in transparency and incident readiness. Overall, the security measures are robust and appropriate for a financial institution, minimizing risk exposure.

Recommendations

  1. Implement and publicize a formal vulnerability disclosure program to encourage responsible reporting of security issues.
  2. Enhance visibility and accessibility of incident response contacts for security-related communications.
  3. Regularly audit and update third-party scripts to mitigate supply chain risks.
  4. Continue to improve accessibility features to maintain compliance and user inclusivity.
  5. Maintain and update security headers and policies in line with evolving best practices.

Technical notes

Notes

The website is built on a modern technical stack including JavaScript, jQuery, and advanced analytics platforms such as Google Analytics, Adobe Analytics, and Tealium. The CMS is likely Adobe Experience Manager, indicated by client library paths and CQ references. Hosting appears to be via Akamai CDN, supporting performance and security. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA labels. Performance monitoring is implemented using Boomerang. The technical implementation is solid with good SEO and metadata practices. Opportunities exist to further modernize by reducing reliance on legacy libraries like jQuery and enhancing real-time security monitoring.
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.
