Mastercard.fi is the Finnish localized website of Mastercard, a global leader in payment technology and services.

The technical infrastructure leverages Akamai CDN and Adobe Launch for analytics and marketing tag management. Security posture is strong with HTTPS enforced and no visible vulnerabilities, though explicit security headers like Content-Security-Policy could be improved.

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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

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

Mastercard operates as a key player in the finance and technology sectors, providing payment processing and digital transaction services globally. The Finnish site supports local market engagement with tailored content and services. The business model focuses on enabling secure, fast, and accessible payment experiences for consumers and businesses. Partnerships with travel rewards and event ticketing services indicate diversified revenue streams. The site’s use of advanced digital experience platforms and consent management tools reflects a commitment to regulatory compliance and user experience. Mastercard’s market position as a global payment technology leader is reinforced by consistent branding and integration with parent and partner domains.

Security posture

The website demonstrates a solid security foundation with HTTPS and no exposed sensitive data. The integration of OneTrust for cookie consent indicates attention to privacy regulations such as GDPR. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for enhancement. No vulnerable or outdated libraries were detected in the HTML content. The site lacks visible incident response or security contact information, which could be improved to enhance transparency and readiness. Overall, the security posture is strong but could benefit from additional header implementations and published security policies.

Recommendations

  1. Implement and enforce Content-Security-Policy and other security headers to mitigate XSS and clickjacking risks.
  2. Publish clear privacy policy and terms of service pages with accessible links on the homepage.
  3. Add visible contact information including security incident response contacts to improve transparency.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update accordingly.
  5. Enhance user trust by displaying certifications or compliance badges related to security and privacy.

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.
