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

Mergado is a Czech-based company specializing in e-commerce data management and feed optimization services. Their platform offers tools such as Mergado Editor, Audit, Pack, and automatic pricing solutions to help online shops increase sales via popular marketplaces and advertising channels like Heureka, Google Shopping, and others. The company maintains a multilingual presence targeting Czech, Slovak, English, and Hungarian markets, positioning itself as a key player in the regional e-commerce technology sector. Technically, the website is built on Drupal CMS with modern frontend technologies including Alpine.js and integrates multiple analytics and tracking services such as Google Tag Manager, Matomo, and Seznam.cz tracking. Security posture is strong with HTTPS enforced and multiple security headers present, although explicit privacy and terms of service documents are not clearly found, which is a compliance gap. WHOIS data is not publicly available, indicating privacy protection, which is justified for this business type. Overall, Mergado presents a professional and trustworthy online presence with room for improvement in transparency and compliance documentation.

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

2 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.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Mergado operates in the e-commerce technology sector, providing SaaS solutions for product feed management and optimization. Their business model revolves around subscription and service offerings that enable e-shops to enhance their product data quality and advertising effectiveness. The company leverages partnerships and integrations with major marketplaces and advertising platforms, strengthening its ecosystem. The multilingual websites and dedicated service domains indicate a strategic approach to regional market penetration. The absence of direct contact details on the main site suggests a focus on digital self-service and account-based customer management. The company likely generates revenue through platform subscriptions, add-on services, and partner certifications. Growth indicators include active content marketing via blogs, academy training, and a partner certification program.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive set of security headers including HSTS, CSP, X-Content-Type-Options, and others. The use of cookie consent mechanisms via CookieHub indicates awareness of privacy regulations. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of explicit privacy policy, terms of service, and incident response contact information are notable compliance and transparency gaps. There is no evidence of a vulnerability disclosure program or security.txt file. Overall, the security practices are solid but could be enhanced by publishing formal policies and contact channels for security incidents.

Recommendations

  1. Publish a comprehensive privacy policy page detailing GDPR compliance and data handling practices.
  2. Add terms of service and security policy documents accessible from the website footer or main navigation.
  3. Provide clear contact information including dedicated security incident response emails (e.g., security@ or abuse@).
  4. Implement a vulnerability disclosure program and publish a security.txt file to improve transparency and trust.
  5. Regularly review and update cookie consent and tracking disclosures to maintain compliance with evolving privacy laws.

Notes

The website is built on Drupal CMS, leveraging modern frontend technologies such as Alpine.js for interactivity. It integrates multiple analytics platforms including Google Tag Manager, Matomo, and Seznam.cz tracking scripts. Cookie consent is managed via CookieHub, indicating a proactive approach to privacy compliance. The site is mobile optimized with responsive design and accessibility features. Performance is moderate, with preloading of fonts and asynchronous loading of scripts. The technical infrastructure appears well-maintained with no obvious technical debt or deprecated libraries visible in the HTML. Hosting provider details are not explicitly found. Overall, the technical implementation supports a professional and scalable e-commerce SaaS platform.
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.
