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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Visa operates as a payment processing and financial services provider with a strong market position as a global leader. Its business model focuses on enabling digital payments across multiple sectors and customer segments. The website reflects Visa's strategic emphasis on innovation, fintech partnerships, and support for small businesses and governments. Revenue streams likely include transaction fees, consulting services, and technology solutions. The extensive network of related domains and partners indicates a broad ecosystem. Visa's brand consistency and trust signals such as comprehensive policies and social media presence reinforce its credibility and market leadership.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, use of secure scripts, and privacy consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit presence of security headers like X-Frame-Options and Content-Security-Policy should be verified to enhance protection against clickjacking and content injection attacks. Incident response and vulnerability disclosure information are not prominently available, suggesting an area for improvement. Overall, Visa demonstrates strong security practices aligned with industry standards, supporting its role as a trusted payment provider.

Recommendations

  1. Verify and explicitly implement security headers such as X-Frame-Options and X-Content-Type-Options.
  2. Publish clear incident response and vulnerability disclosure policies to enhance transparency and trust.
  3. Regularly audit third-party scripts and analytics tools for vulnerabilities and privacy compliance.
  4. Enhance visibility of direct contact information for security and privacy inquiries.
  5. Continue investment in privacy compliance and user consent mechanisms to maintain regulatory alignment.

Technical notes

Notes

The website is built using modern web technologies including Stencil.js for component-based UI, integrates with YouTube API, Google Tag Manager, Optimizely for A/B testing, and Tealium for tag management. The CMS appears to be Adobe Experience Manager, indicating a robust enterprise-grade content platform. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and structured data. Opportunities exist to optimize loading times further and confirm all security headers are in place. The technical infrastructure supports a scalable and secure digital presence suitable for a global financial services leader.
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.
