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. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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

Santander operates in the finance sector with a global footprint, serving 176 million customers across Europe and the Americas. The business model focuses on retail banking and consumer finance, supported by subsidiaries like Openbank and Santander Consumer Finance. The website targets investors, customers, and job seekers, providing comprehensive investor relations, press releases, and career opportunities. The company emphasizes sustainability, financial inclusion, and innovation, positioning itself as a responsible and forward-looking financial services provider. The digital presence is consistent with enterprise standards, supporting brand trust and customer engagement.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, multiple security headers, and a cookie consent mechanism aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit incident response contact information and a vulnerability disclosure policy represents an area for improvement. The use of third-party scripts like Tealium for analytics and tag management is noted, which requires ongoing monitoring for security risks. Overall, the security maturity is high but could benefit from enhanced transparency and incident response readiness.

Recommendations

  1. Publish explicit incident response and security contact information on the website to improve transparency and readiness.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  3. Enhance accessibility features by adding ARIA landmarks and improving keyboard navigation support.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Increase visibility of contact information for customers and stakeholders to strengthen trust and support.

Technical notes

Notes

The website is built on Adobe Experience Manager, leveraging jQuery, Tealium tag management, and other modern JavaScript libraries. The site is mobile responsive with good SEO and accessibility practices. Performance is moderate, with asynchronous loading of analytics scripts and optimized images. The technical infrastructure supports a large enterprise with complex content and navigation needs. Opportunities exist to improve performance further and enhance accessibility compliance. No critical technical debt or risks were identified from the HTML content.
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.
