Security score

75/100

Risk levelMedium

0–100, higher is better. How it is calculated

Visa Korea operates as a regional digital payment leader providing secure and innovative payment solutions tailored for both individual and corporate customers. The website reflects Visa's global brand identity and commitment to financial inclusion, security, and sustainability. The site is well-structured, mobile-optimized, and rich in relevant content, supporting Visa's market position as a trusted financial services provider. Technically, the site leverages modern web technologies including Stencil.js, Google Tag Manager, and Tealium for analytics and marketing, hosted likely on a robust enterprise CMS platform (Adobe Experience Manager). Security posture is strong with HTTPS enforcement and security headers, though explicit security policies and incident response contacts are not published. Privacy compliance is well addressed with comprehensive policies and cookie consent mechanisms. The absence of WHOIS data is unusual but does not detract from the site's legitimacy given the strong brand presence and content quality.

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 Korea targets a broad audience including consumers and businesses seeking digital payment solutions. The business model centers on providing payment card products, contactless payment technologies, and B2B financial services. Visa's competitive advantage lies in its global network, brand trust, and continuous innovation in payment technologies. The website ecosystem includes numerous regional Visa domains and partner portals, indicating a well-integrated global partnership network. Growth indicators include active promotions and innovation center links. The site supports Visa's strategic goals of expanding financial inclusion and sustainable commerce in the Korean market.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of security headers, and no visible vulnerabilities or exposed sensitive data. Privacy and cookie policies are comprehensive and GDPR compliant, with active consent mechanisms. However, the site lacks a publicly accessible security policy or incident response contact details, which are recommended best practices for enterprise financial websites. No vulnerability disclosure or security.txt files were found. Overall, the security culture appears strong but could be enhanced by publishing explicit security governance information and direct security contacts.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure program or security.txt file.
  4. Regularly review and audit third-party scripts and analytics tags for security risks.
  5. Enhance accessibility features to meet or exceed WCAG standards for inclusivity.

Technical notes

Notes

The website is built on a modern technical stack including Stencil.js for web components, integrated with Google Tag Manager and Tealium for analytics and marketing automation. It uses Adobe Experience Manager as the CMS platform, indicating enterprise-grade content management capabilities. The site is well-optimized for performance and mobile responsiveness, with good SEO practices including meta tags and structured data (JSON-LD). No technical debt or legacy technology indicators were found. Hosting details are not explicit but likely enterprise cloud-based. The technical infrastructure supports a high-quality user experience and robust content delivery.
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.
