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

COOP MORAVA, s.r.o. operates the naCOOPka website and mobile application, which serves as a loyalty and promotional platform for COOP retail stores in the Czech Republic. The app provides users with digital loyalty cards, automatic contest code registration, store locators, and access to promotional flyers. The website is professionally designed with clear navigation and mobile optimization, targeting COOP customers effectively. Technically, the site uses modern front-end technologies including StimulusJS and Embla Carousel, and integrates Google Tag Manager for analytics and marketing. Security-wise, HTTPS is implied, and a cookie consent mechanism is implemented, but there is a lack of visible security headers and formal security policies. The absence of WHOIS data limits domain trust verification, though the website content and contact details support legitimacy. Overall, the site presents a good security posture with room for improvement in formal policies and technical security headers.

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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 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';…
  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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 business is positioned as a regional retail loyalty service provider for COOP Morava customers, leveraging a mobile app to enhance customer engagement and retention. Its competitive advantage lies in integrating loyalty, contests, and store information in one platform. The business model focuses on customer loyalty and promotional marketing within the retail sector. The company maintains an active social media presence and provides clear contact and legal information, indicating transparency and professionalism. Growth potential is supported by digital engagement and app availability on major platforms. Partnerships with Google services for analytics and marketing are evident, but no other partner domains were identified.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and a comprehensive cookie consent mechanism that supports GDPR compliance. However, it lacks explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No vulnerability disclosure or incident response information is provided, which could hinder timely security issue reporting and resolution. The absence of WHOIS data reduces domain registration transparency, though no direct vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is adequate for a retail loyalty platform but could be enhanced by adopting best practices and formal policies.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a clear privacy policy page detailing data processing practices to improve GDPR compliance and user trust.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.
  5. Enhance domain registration transparency by ensuring WHOIS data is complete and publicly accessible.

Technical notes

Notes

The website employs a modern front-end stack with HTML5, CSS3, and JavaScript frameworks such as StimulusJS and Embla Carousel for UI interactions. Google Tag Manager is used for analytics and marketing tracking. The site is mobile-optimized with responsive design and accessibility features like skip links and ARIA roles. Performance is moderate with asynchronous script loading and preconnect hints for fonts. However, no CMS or hosting provider information is detectable. The site lacks advanced security headers and formal security policies, representing technical debt in security posture. Overall, the technical infrastructure supports a good user experience but could benefit from enhanced security and performance optimizations.
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.
