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 an essential entity in the finance sector, providing payment processing and consulting services globally. The Mexican site targets both consumers and businesses, offering products like Visa Credit, Debit, and prepaid cards, as well as advanced solutions such as Visa Direct and Visa Secure 3DS. Visa's business model revolves around facilitating secure and innovative payment technologies, supported by a broad partner ecosystem including insurance and assistance providers. The website content and structure indicate a large enterprise with a well-established brand, strong global partnerships, and a focus on digital transformation and customer empowerment.

Security posture

The website exhibits a high security maturity level with enforced HTTPS, comprehensive security headers, and use of Cloudflare for rate limiting and bot management. Privacy compliance is robust with clear cookie consent and privacy policies aligned with GDPR. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a dedicated security policy or vulnerability disclosure page and lack of explicit incident response contact details suggest areas for improvement in transparency and readiness. Overall, Visa.com.mx maintains a secure environment appropriate for a financial services leader.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide explicit incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention policies and user privacy controls.
  5. Continue monitoring and updating third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack including Stencil.js for web components, Adobe Experience Manager as CMS, and Cloudflare for security and performance. It uses advanced analytics and marketing tools such as Tealium and Optimizely for user tracking and optimization. The site is well-optimized for mobile devices and accessibility, with proper semantic HTML and ARIA attributes. Performance is fast, supported by CDN usage and efficient resource loading. Technical risks are minimal, but continuous updates and security audits are recommended to maintain resilience.
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.
