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 in the finance and technology sectors, focusing on payment processing and digital payment innovations. The business model revolves around enabling secure and convenient payment methods globally. The website targets consumers, businesses, and fintech partners, providing resources, support, and innovation programs. Visa's extensive international presence is evident through numerous regional domains and multilingual support. The company maintains a strong partnership ecosystem and invests in social impact and sustainability initiatives. The website content and structure reinforce Visa's market leadership and commitment to innovation and inclusion.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, comprehensive security headers, and use of Cloudflare for DDoS mitigation and rate limiting. Cookie consent mechanisms and privacy policies align with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact information limits transparency. There is also no published vulnerability disclosure or security.txt file, which are best practices for mature security programs. Overall, the security posture is strong but could benefit from enhanced communication and disclosure.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and audit third-party scripts and tracking technologies for security and privacy compliance.
  5. Enhance contact information with direct phone numbers or emails for customer and security support to improve trust.

Technical notes

Notes

The website uses modern web technologies including Stencil.js for component-based UI, Cloudflare for CDN and security, and advanced analytics tools like Tealium, ContentSquare, and Catchpoint for performance and user experience monitoring. The CMS appears to be Adobe Experience Manager, supporting a scalable and flexible content delivery. The site is well optimized for mobile devices and accessibility, with good SEO practices including hreflang tags for internationalization. Performance is fast, and the technical infrastructure supports a robust and professional online presence. Opportunities exist to further modernize by consolidating third-party scripts and enhancing security disclosures.
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.
