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

Imper CZ s.r.o. operates the Merk business database platform, a comprehensive B2B marketing and sales tool serving over 15,000 users across more than 2,000 companies in the Czech and Slovak Republics. The platform aggregates data from over 4,000 sources, covering more than 4 million business entities and 2.2 million individuals, providing verified contact details and business intelligence to support client acquisition and market analysis. The company positions itself as a leading provider of business data services in the region, emphasizing data quality, GDPR compliance, and integration capabilities including API and CRM modules. Technically, the website is built on WordPress with a modern tech stack including jQuery, Google Tag Manager, and multiple marketing and analytics tools such as HubSpot and Intercom. The site is mobile-optimized and employs cookie consent management via Complianz and Cookiebot, reflecting a mature digital presence. Performance is moderate with good SEO and accessibility basics. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers like Content-Security-Policy and X-Frame-Options are not detected, representing an area for improvement. No critical vulnerabilities or exposed sensitive data were found. However, the absence of WHOIS registration data reduces domain trustworthiness and warrants further investigation. Overall, the website and business demonstrate professionalism, compliance, and a strong market position, but the missing WHOIS data and some security header gaps suggest areas for enhancement to improve trust and security posture.

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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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

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

Business profile

Imper CZ s.r.o. targets B2B companies and sales/marketing professionals in Czechia and Slovakia, offering a subscription-based business database service with verified contacts and rich business intelligence. The company leverages a large data aggregation ecosystem and provides integration options via API and CRM modules. Its competitive advantage lies in data quality, frequent updates, and comprehensive coverage of the local market. The presence of reputable client logos and GDPR compliance strengthens its market credibility. The business model focuses on recurring revenue from data services and marketing tools, with growth potential in data-driven sales solutions and AI-powered offerings (MerkAI). Strategic partnerships with related platforms like Leady and Mediaboard expand its ecosystem.

Security posture

The website enforces HTTPS and uses cookie consent management tools, indicating compliance with GDPR and user privacy standards. Security best practices include no visible exposure of sensitive data and use of reputable third-party plugins. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No incident response or security policy information is publicly available, which could hinder transparency and readiness. The site uses multiple third-party scripts for analytics and marketing, which require ongoing monitoring to mitigate supply chain risks. Overall, the security posture is good but can be improved by adding missing headers and publishing security policies.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to enhance security.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and preparedness.
  3. Regularly audit and update all third-party scripts and plugins to minimize vulnerabilities.
  4. Investigate and resolve the missing WHOIS registration data to improve domain trust and legitimacy.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance and security posture.

Technical notes

Notes

The website is built on WordPress CMS with a modern JavaScript stack including jQuery and Slick Carousel. It integrates multiple marketing and analytics tools such as Google Tag Manager, HubSpot, Intercom, and LinkedIn Insight Tag. Cookie consent is managed via Complianz and Cookiebot plugins, reflecting GDPR compliance. The site loads moderately fast and is mobile-optimized with responsive design. SEO is well implemented with proper meta tags, Open Graph, and JSON-LD structured data. However, some security headers are missing, and hosting provider details are not explicitly identified. The technical infrastructure supports a professional B2B service but could benefit from enhanced security configurations and performance tuning.
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.
