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

Klarna is a leading European payment service provider that has integrated Sofortüberweisung into its platform, offering customers a seamless, secure, and familiar payment experience. The website clearly targets German-speaking shoppers and merchants, providing detailed information about payment options, security features, and customer support. The site is professionally designed, mobile-optimized, and rich in content, reflecting Klarna's strong market position and brand consistency. Technically, the site leverages modern web technologies including React and Emotion CSS, and integrates widely used analytics and advertising services such as Google Analytics and DoubleClick. Security practices include HTTPS enforcement and secure login flows, though explicit security headers and incident response contacts are not evident on this page. The WHOIS data for the domain is unavailable, which is unusual but likely due to privacy protection or query limitations; however, the website content and branding strongly support legitimacy. Overall, Klarna's site demonstrates a mature digital presence with good security posture and privacy compliance, suitable for its role as a financial services provider.

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

7 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Klarna operates in the finance and e-commerce sectors, offering flexible payment solutions including immediate payment, pay later, installment plans, and a dedicated app for transaction management. The company targets online shoppers and merchants primarily in Germany, emphasizing convenience, security, and buyer protection. Klarna's business model centers on providing payment infrastructure and financial services that enhance the checkout experience and reduce friction. The website content highlights Klarna's competitive advantages such as multi-factor authentication, buyer protection policies, and a unified app experience. The presence of multiple Klarna-owned domains and integration with global advertising and analytics platforms indicates a robust partnership and marketing ecosystem. Klarna's market position is strong, supported by consistent branding and comprehensive customer support resources.

Security posture

The website enforces HTTPS and uses secure login links, indicating a baseline of security best practices. The content mentions advanced security features such as multi-factor authentication and buyer protection, which are key trust signals for users. However, the absence of visible security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options in the provided data suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks a published security policy or incident response contact information, which are important for transparency and compliance. Overall, the security posture is good but could be enhanced by publishing explicit security documentation and implementing additional HTTP security headers.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve transparency with security researchers.
  4. Ensure all external scripts and libraries are regularly audited and updated to mitigate risks from vulnerable dependencies.
  5. Enhance user trust by including more visible trust seals, certifications, or compliance badges related to data protection and security.

Notes

The website is built using React with Emotion for styling, indicating a modern and maintainable front-end architecture. It preloads fonts and critical CSS for performance optimization and uses multiple CDN domains for static assets, improving load times globally. Integration with Google Tag Manager and Google Analytics enables comprehensive user behavior tracking and marketing analytics. The site is mobile-optimized with responsive design and accessibility considerations such as focus-visible styles and semantic HTML elements. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports a fast, reliable, and user-friendly experience with opportunities to strengthen security and compliance features.
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.
