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

Aldermore Bank is a UK-based specialist bank offering a range of financial products including mortgages, savings accounts, and business finance solutions. The website presents a professional and well-structured digital presence with clear branding and product segmentation. The technical infrastructure leverages modern web technologies, including Google Tag Manager, Microsoft Application Insights for monitoring, and OneTrust for cookie consent management, indicating a mature digital setup. Security posture is strong with HTTPS enforced and standard security practices observed, though some advanced headers could be added for enhanced protection. Privacy compliance is supported by a cookie consent mechanism, but explicit privacy policy and terms of service pages were not detected in the provided content. WHOIS data could not be retrieved due to querying a subdomain rather than the registered domain, which slightly impacts trust but the website content and branding strongly indicate legitimacy. Overall, Aldermore Bank's website is professional, secure, and user-friendly, serving its target audience effectively.

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

1 finding 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

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

Aldermore Bank operates in the finance sector, targeting both personal and business customers with specialist mortgages, savings, and business finance products. The bank positions itself as an award-winning institution focusing on equality and supporting exceptions to the rule. The business model is centered on providing tailored financial solutions rather than mass-market banking. The website's content and structure suggest a medium-sized enterprise with a focus on digital engagement and customer support. The presence of Trustpilot integration and Google Search Console verification indicates active reputation management and SEO efforts. No direct contact information or detailed corporate data was found in the provided content, which may be available elsewhere on the site. The bank likely benefits from partnerships and uses cloud-based hosting and analytics services to support its operations.

Security posture

The website enforces HTTPS and uses security best practices such as cookie consent and monitoring via Microsoft Application Insights. Security headers are partially present but could be improved by adding Content-Security-Policy and other advanced headers. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy or incident response information limits transparency. The lack of visible contact channels for security incidents is a gap. Overall, the security posture is good but could be enhanced with more explicit policies and communication channels. The use of trusted third-party services and CDN hosting contributes positively to security and performance.

Recommendations

  1. Add explicit security headers such as Content-Security-Policy and Referrer-Policy to enhance protection against common web attacks.
  2. Publish a clear privacy policy and terms of service accessible from the homepage to improve compliance and user trust.
  3. Provide visible contact information including emails and phone numbers for general and security-related inquiries.
  4. Implement and publish an incident response policy and contact channels to demonstrate readiness and transparency.
  5. Enhance accessibility features to improve compliance with standards and user experience for all visitors.

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.
