LEANO.cz is a Czech Republic-based price comparison platform specializing in pharmacy, cosmetic, and health-related products. Operated by PPJ s.r.o., the website offers consumers a way to find the best prices across multiple online pharmacies and cosmetic stores. The platform features extensive categorization, city-specific pharmacy listings, and editorial content such as reviews and articles to support informed purchasing decisions. The business model primarily revolves around affiliate marketing and providing a convenient shopping list feature for users. Technically, the website employs modern web technologies including jQuery, the Nette framework, Google Tag Manager, and MailerLite for marketing automation. It is well-optimized for mobile devices and includes SEO best practices such as structured data markup. Security-wise, the site enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. However, the absence of WHOIS registration data and lack of explicit contact information or security policy pages slightly reduce trustworthiness.

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.

Priority findings

8 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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

LEANO.cz occupies a niche position in the Czech retail market as a specialized price comparison service for pharmacy and cosmetic products. Its competitive advantage lies in localized content, including city-specific pharmacy listings and a broad product categorization that caters to diverse consumer needs. The platform leverages partnerships with major online pharmacies such as Pilulka, Dr. Max, and TETA, enhancing its market reach and affiliate revenue potential. The business targets health-conscious consumers and shoppers seeking cost savings on pharmaceutical and cosmetic goods. Growth indicators include a well-maintained content magazine and integration of marketing tools like MailerLite. The company appears to operate as a small-sized entity with focused sector expertise. Strategic observations suggest opportunities to enhance trust by publishing more transparent business and security information and expanding contact channels.

Security posture

The website demonstrates a good baseline security posture with HTTPS enforced and a functional cookie consent mechanism aligned with GDPR requirements. The use of Google Analytics and Facebook Pixel is disclosed via cookie settings, indicating transparency in tracking practices. However, the absence of security headers such as Content-Security-Policy and lack of a published security policy or incident response page represent gaps in security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data raises concerns about domain registration transparency, which could impact overall trust. The site would benefit from implementing security.txt and publishing clear incident response contacts to improve readiness and compliance. Overall, the security posture is moderate with room for improvement in formal policies and technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page detailing procedures and contact information to improve transparency and preparedness.
  3. Add a security.txt file at the root domain to facilitate vulnerability disclosure and responsible reporting.
  4. Verify and publish domain WHOIS registration details to improve domain trust and legitimacy perception.
  5. Enhance contact information availability by adding verified company emails and phone numbers to support user trust and compliance.

Technical notes

Notes

The website is built on a modern technology stack featuring jQuery 3.2.1 and the Nette PHP framework for backend and AJAX functionality. It integrates third-party services such as Google Tag Manager for analytics and MailerLite for email marketing automation. The frontend uses Font Awesome icons and Google Fonts for styling, with custom CSS for layout and responsive design. Performance is moderate with asynchronous loading of scripts and optimized assets. Mobile optimization is good, ensuring usability across devices. SEO is supported by meta tags, Open Graph data, and JSON-LD structured data for organization and search actions. No CMS was explicitly detected, suggesting a custom or framework-based solution. Hosting provider details are not disclosed. Technical risks include lack of advanced security headers and incomplete domain registration 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.
