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

Priceless.com is a premium experience platform exclusively for Mastercard cardholders, offering access to unique events and travel experiences primarily targeting the German market. The website is well-branded with Mastercard's identity and provides a professional user experience with clear navigation and localized German content. Technically, the site employs modern JavaScript libraries, CDN hosting via Amazon CloudFront, and integrates analytics and marketing tools such as Adobe DTM and Google Analytics. Security posture is strong with HTTPS enforced, security headers implemented, and a cookie consent mechanism in place. However, the absence of WHOIS registration data and explicit incident response contacts slightly reduces trust. Overall, the site appears legitimate and professionally maintained, aligned with Mastercard's brand standards.

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

1 finding 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

      • 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

Priceless.com leverages Mastercard's brand to deliver exclusive lifestyle and travel experiences to cardholders, positioning itself as a value-added service in the finance and hospitality sectors. The business model focuses on curated experiences, likely generating revenue through partnerships and event bookings. The platform targets affluent Mastercard users in Germany and possibly other regions, supported by localized content and currency settings. The site integrates with Mastercard's broader ecosystem, enhancing customer loyalty and engagement. The lack of direct contact information on the main site suggests a controlled communication channel, typical for large brands. The partnership with Mastercard ensures strong market positioning and trust.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a cookie consent mechanism compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of a security.txt file or explicit vulnerability disclosure page limits transparency for security researchers. Incident response contact information is not publicly available, which could delay reporting and remediation of security issues. Regular audits of third-party libraries and enhanced accessibility compliance are recommended to maintain and improve security and compliance standards.

Recommendations

  1. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  2. Provide explicit incident response contact information, such as security@ or abuse@ email addresses.
  3. Enhance website accessibility features to meet WCAG standards for broader compliance.
  4. Regularly review and update third-party libraries to mitigate potential vulnerabilities.
  5. Maintain transparency on data retention policies and update privacy documentation accordingly.

Technical notes

Notes

Priceless.com is built on a modern web technology stack including Bootstrap 4.6 for responsive design, jQuery, React Timeline, and various JavaScript libraries for UI enhancements and analytics. The site uses Amazon CloudFront as a CDN for asset delivery, improving performance and scalability. Integration with Adobe DTM and Google Analytics indicates a sophisticated marketing and analytics setup. The site is mobile-optimized with good SEO practices and basic accessibility features. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is moderate, with potential for optimization in loading times and accessibility compliance.
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.
