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 maintains a dominant position in the Brazilian payments market, targeting both individual consumers and businesses with a broad portfolio of card products and digital payment solutions. The business model centers on facilitating secure, efficient transactions and enabling commerce innovation through technologies like Tap to Phone and Click to Pay. The company benefits from a global parent, Visa Inc., and a wide partner ecosystem including AXA for benefits and concierge services. The website's extensive regional domain network and multilingual support indicate a strong international presence and localization strategy. Visa's focus on social impact, community support, and sustainability is evident in dedicated site sections, enhancing brand reputation and stakeholder engagement.

Security posture

The website exhibits a high level of security maturity, employing HTTPS with strong SSL/TLS configurations and leveraging Cloudflare for DDoS mitigation and rate limiting. Cookie consent is managed via a comprehensive banner with granular controls, supporting GDPR compliance. Security headers are inferred to be in place, and session management uses secure cookies. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a publicly accessible security policy or vulnerability disclosure program limits transparency. Incident response contact information is not found, which could be improved to enhance trust and readiness. Overall, the security posture is robust but could benefit from enhanced public communication of security governance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data protection officer contact details to support GDPR compliance.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern technical stack including Stencil.js for UI components, hosted behind Cloudflare CDN for performance and security. It uses Adobe Experience Manager as CMS, enabling scalable content management. Integration with multiple analytics and marketing platforms such as Google Analytics, Tealium, Optimizely, and Eloqua supports data-driven marketing and user experience optimization. The site is mobile-optimized with responsive design and accessibility features. Performance is fast with preloading and lazy loading techniques. Technical risks are minimal, but reliance on multiple third-party scripts requires ongoing security monitoring to prevent supply chain risks.
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.
