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

2 findings rated critical or high. Fix these first.

  1. 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's business model centers on providing secure, innovative payment technologies and services globally. The Slovak site integrates with Visa's worldwide network, linking to numerous regional Visa domains and partner sites. The company leverages partnerships and analytics platforms to optimize service delivery and marketing. Visa's offerings include payment acceptance solutions for merchants, consulting and analytics services, and tokenization technology. The site highlights Visa's commitment to social impact, inclusion, and sustainability, reinforcing its brand values and market differentiation.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent mechanisms, and use of reputable third-party security and analytics services such as Cloudflare and Tealium. While explicit security headers are not fully confirmed in the HTML, the site avoids exposing sensitive data and uses secure cookies. However, the absence of a dedicated security policy page or incident response contact limits transparency. No vulnerability disclosure or security.txt file is present, suggesting room for improvement in formal security communication and incident management readiness.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and confirm security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance transparency by publishing Data Protection Officer contact information.

Technical notes

Notes

The website is built on a modern technology stack including JavaScript frameworks (Stencil), tag management (Tealium), and analytics platforms (ContentSquare, Eloqua). It uses Adobe Experience Manager as CMS, served via Cloudflare CDN for performance and security. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with room for optimization. The technical infrastructure supports a professional and scalable digital presence aligned with Visa's global standards.
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.
