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

PENTA CZ operates as a Czech Republic-based e-commerce retailer specializing in a broad range of products including household goods, garden supplies, tools, and electronics. The website offers a loyalty program and expert advice, targeting both consumers and businesses. The platform is well-structured with extensive product categories, indicating a mature retail operation with a medium-sized market presence. Technically, the website employs modern JavaScript libraries such as jQuery and integrates Google Tag Manager, Google Analytics, and reCAPTCHA for analytics and security. Cookie consent mechanisms are implemented, reflecting awareness of privacy regulations. However, the absence of a visible privacy policy and security headers suggests areas for improvement in compliance and security hardening. Security posture is moderate with HTTPS enabled and use of reCAPTCHA, but lacks visible security headers and vulnerability disclosure mechanisms. The WHOIS data is unavailable, likely due to privacy protection, which limits domain trust assessment. Overall, the site appears legitimate and professionally maintained but would benefit from enhanced transparency and security practices. Strategic recommendations include publishing comprehensive privacy and security policies, implementing security headers, and establishing a vulnerability disclosure process to strengthen trust and compliance.

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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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

PENTA CZ holds a solid position in the Czech retail e-commerce sector, offering a wide product range that caters to household, garden, and office needs. Its business model focuses on direct online sales supported by loyalty programs and expert customer support. The company targets a broad audience including individual consumers and businesses, leveraging partnerships with logistics providers like Packeta. The extensive product categorization and marketing integrations indicate a well-developed digital sales infrastructure. Growth potential lies in expanding privacy compliance and security transparency to enhance customer trust and regulatory adherence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and Google reCAPTCHA protecting user inputs. Cookie consent management is implemented, indicating some GDPR awareness. However, the absence of key security headers (e.g., Content-Security-Policy, X-Frame-Options) and lack of published security policies or incident response contacts reveal gaps in security best practices. No vulnerability disclosure or security.txt file was found, limiting external reporting capabilities. These gaps could expose the business to risks such as clickjacking or cross-site scripting if not addressed. Overall, the security posture is functional but requires enhancements to meet higher compliance and protection standards.

Recommendations

  1. Publish a comprehensive privacy policy detailing data collection, processing, and user rights to improve GDPR compliance.
  2. Implement and configure essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Create and publish a security.txt file or vulnerability disclosure policy to facilitate responsible security reporting.
  4. Enhance accessibility features and conduct audits to improve user experience for all users.
  5. Increase transparency by providing clear contact information including security and data protection officer contacts.

Technical notes

Notes

The website uses a traditional web stack with jQuery and jQuery UI libraries, integrated with Google Tag Manager and Analytics for tracking, and Google reCAPTCHA for bot protection. Marketing tools include Targito and Heureka widgets, and logistics integration via Packeta. The site loads external fonts from Google Fonts and uses asynchronous script loading to optimize performance. Mobile optimization is good, with responsive design evident. However, no CMS or hosting provider information was detected. Performance is moderate, with potential improvements in modernizing the tech stack and enhancing accessibility and SEO features. Security headers are missing, representing a technical risk. Overall, the infrastructure supports a stable e-commerce platform but could benefit from modernization and security hardening.
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.
