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

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 as an important entity in the e-commerce sector, leveraging affiliate partnerships with major online retailers such as Alza.cz, AliExpress, Allegro, and Booking.com. Its business model centers on providing cashback incentives to shoppers, driving traffic and sales to partner e-shops. The platform's extensive partner network and user base indicate strong market positioning in the Czech Republic. Revenue streams likely include affiliate commissions and advertising. The company maintains active social media channels and offers browser extensions and mobile apps to enhance user engagement. Founded around 2012 and operated by 5DM.cz, s.r.o., the business shows signs of steady growth and digital maturity.

Security posture

The website enforces HTTPS and integrates security best practices such as Google reCAPTCHA and OAuth-based logins, enhancing user authentication security. Cookie consent is managed with granular user controls, supporting privacy compliance. However, the site lacks visible HTTP security headers like Content Security Policy or HSTS, which could further harden security. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of a published security policy or incident response plan is a gap that could be addressed to improve transparency and readiness. Overall, the security posture is good but could benefit from additional hardening and documentation.

Recommendations

  1. Implement and publish comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Provide a dedicated security policy page outlining incident response procedures and contact channels.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance transparency by publishing data retention policies and privacy impact assessments.
  5. Consider adding explicit contact information such as phone numbers and physical addresses to improve business credibility.

Technical notes

Notes

The website uses a modern and diverse technology stack including jQuery 3.6.0, Google Identity Services, Facebook SDK, Google reCAPTCHA, and Apple Sign-In APIs. It employs custom JavaScript controllers for UI components and user interactions. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with some reliance on external CDNs and third-party scripts. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical infrastructure supports a robust user experience but could be enhanced by adding security headers and optimizing script loading for faster performance.
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.
