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

Plná Peněženka is a leading cashback portal based in the Czech Republic, offering users cashback rewards, discounts, and coupons from over 1100 partner shops domestically and internationally. The platform boasts over one million registered users and has paid out more than 246 million CZK in cashback, positioning itself as the largest cashback service in the Czech market. The business model revolves around affiliate partnerships, sharing commissions with users to incentivize online shopping through their platform. Technically, the website employs modern JavaScript libraries and OAuth integrations for social logins, ensuring a seamless user experience across web and mobile platforms. Security measures include HTTPS enforcement, use of Google reCAPTCHA, and cookie consent mechanisms, although explicit security headers could be further verified. The absence of WHOIS data limits domain registration trust verification, but the professional site presence and comprehensive policies indicate a legitimate and mature operation.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

The company operates in the e-commerce sector, targeting online shoppers seeking cashback and savings. Its competitive advantage lies in its extensive partner network, user-friendly interface, and strong brand presence supported by mobile apps and browser extensions. Revenue streams likely include affiliate commissions and possibly advertising. The platform's growth is evidenced by its large user base and significant cashback payouts. Partnerships with major retailers like Alza, AliExpress, and Samsung enhance its market position. Strategic observations include the importance of maintaining trust through transparent policies and expanding offers to retain user engagement.

Security posture

The website demonstrates a good security posture with HTTPS, OAuth-based social logins, and anti-bot measures via reCAPTCHA. Cookie consent and privacy policies align with GDPR requirements. However, explicit security headers such as X-Frame-Options and Content-Security-Policy are not clearly visible in the provided data and should be confirmed. No vulnerabilities or exposed sensitive data were detected. Incident response and vulnerability disclosure policies are not publicly found, representing an area for improvement. Overall, the security maturity is solid but could benefit from enhanced transparency and formalized security documentation.

Recommendations

  1. Verify and implement comprehensive HTTP security headers including X-Frame-Options and X-Content-Type-Options.
  2. Publish a formal vulnerability disclosure and incident response policy to enhance transparency and trust.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance monitoring and alerting for suspicious activities, especially around login and payment processes.
  5. Continue to improve privacy compliance by detailing data retention policies and user data handling practices.

Technical notes

Notes

The website uses a modern tech stack including jQuery 3.6.0, Google Identity Services, Facebook SDK, Google reCAPTCHA, and Apple Sign-In APIs. The site is mobile-optimized with responsive design and accessibility features. SEO is supported by structured data (JSON-LD) and proper meta tags. Performance is moderate, with preloading of key resources and lazy loading of images. The platform appears custom-built with modular JavaScript controllers. Hosting provider details are not disclosed. Technical risks include potential outdated libraries and incomplete security header implementation. Opportunities exist to improve performance and security transparency.
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.
