RedCart is a well-established Polish e-commerce platform founded in 2008, offering comprehensive solutions for online store creation, sales management, multi-channel selling, and automation. The platform targets e-commerce businesses seeking integrated tools to streamline their operations and increase sales efficiency. With over 100,000 stores created and positive client testimonials, RedCart holds a strong market position in Poland's e-commerce sector.

The platform integrates multiple analytics and marketing tools such as Google Tag Manager, Hotjar, Microsoft Clarity, and Facebook Pixel, indicating a mature digital marketing approach. Security-wise, the site uses HTTPS and DNSSEC, reflecting good domain and transport security.

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

9 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

      Missing Strict-Transport-Security header

      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

RedCart operates as a SaaS e-commerce platform primarily serving Polish online retailers. Its business model focuses on providing an all-in-one solution for store creation, sales automation, and multi-channel management, including integration with popular marketplaces like Allegro. The platform's competitive advantages include a large user base, extensive feature set, and positive customer feedback. Revenue streams likely include subscription fees and value-added services. The target customers are small to medium-sized e-commerce businesses looking for scalable and automated sales solutions. The presence of a dedicated admin domain suggests a structured operational ecosystem. Strategic partnerships and integrations enhance its market reach and service offerings. The company demonstrates growth potential through continuous feature development and a strong client base.

Security posture

The website exhibits a solid security foundation with HTTPS enforced and DNSSEC enabled, reducing risks of interception and DNS spoofing. The use of modern frameworks and absence of exposed sensitive data are positive indicators. However, the lack of visible advanced security headers such as Content-Security-Policy or X-Frame-Options suggests potential areas for enhancement. No direct incident response or vulnerability disclosure information is provided, which could impact readiness for security incidents. The use of multiple third-party tracking scripts necessitates regular security audits to mitigate supply chain risks. Overall, the security maturity is good but could benefit from improved transparency and additional header implementations.

Recommendations

  1. Publish comprehensive privacy and cookie policy pages to improve GDPR compliance and user trust.
  2. Implement additional security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response and vulnerability disclosure contacts to enhance security transparency.
  4. Add visible and verified company contact information including emails and phone numbers for better business credibility.
  5. Regularly review and audit third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website is built on a modern technology stack featuring Next.js and React, ensuring server-side rendering and fast client-side interactions. It uses advanced image optimization and lazy loading techniques for performance. Hosting is provided by OVH SAS, a reputable provider, with DNSSEC enabled for domain security. The site is mobile-optimized with responsive design and good accessibility features. Analytics and marketing integrations are extensive, supporting data-driven business decisions. No major technical debt or outdated technologies are evident. Opportunities exist to enhance security headers and privacy disclosures to align with best practices.
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.
