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

The website zrsr.sk is the official portal of the Ministry of Interior of the Slovak Republic, providing public access to the Trade Licensing Register. It serves as a government service platform enabling users to search for business entities by various criteria such as company ID, trade name, personal names, and addresses. The site targets Slovak citizens, entrepreneurs, and the general public seeking official business registry information. The business model is a public service with no commercial intent, positioned as a trusted government resource. Technically, the website employs modern web standards including HTML5, CSS3, and JavaScript ES modules. It uses the GOV.UK frontend framework and a custom design system (idsk-frontend) tailored for Slovak government services. The site is mobile-optimized and accessible, with moderate performance. Security measures include HTTPS enforcement and a custom CAPTCHA widget to prevent automated abuse. However, some security best practices such as security headers and vulnerability disclosure mechanisms are not implemented. From a security perspective, the site demonstrates a solid baseline with encrypted communications and input validation. The absence of security headers and vulnerability disclosure policies represents areas for improvement. No exposed sensitive data or vulnerabilities were detected in the analyzed content. Privacy compliance is partial, with cookie policy present but lacking explicit consent mechanisms and a dedicated privacy policy page. Overall, the website is a credible, professional government service with high trustworthiness. Strategic recommendations include enhancing security headers, publishing a security policy and incident response contacts, implementing explicit cookie consent, and adding vulnerability disclosure information to improve transparency 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

6 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 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. 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';…

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 Ministry of Interior of the Slovak Republic operates this official trade licensing register portal, positioning itself as the authoritative source for business registration data in Slovakia. The platform supports multiple search modalities catering to diverse user needs, enhancing accessibility to public business information. The government-backed nature ensures high trust and reliability, with no commercial revenue streams. The service supports transparency and regulatory compliance in the Slovak business environment. Partnerships appear limited to internal government domains, reflecting a focused ecosystem. Growth indicators are tied to digital government service adoption and regulatory updates. The platform's strategic value lies in enabling public oversight and facilitating business verification processes.

Security posture

The website maintains a good security posture with mandatory HTTPS and CAPTCHA protection to mitigate automated abuse. Input fields enforce validation patterns and length restrictions, reducing injection risks. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options limits defense-in-depth. No incident response or security contact information is published, which could delay response to security events. Absence of vulnerability disclosure or security.txt reduces transparency for security researchers. Privacy compliance is partial, with cookie policy but no explicit consent mechanism or comprehensive privacy policy. Overall, the site is secure for public use but would benefit from enhanced security controls and transparency.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve security transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance cookie consent mechanisms to comply fully with GDPR and improve user privacy control.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern, modular JavaScript framework using ES modules and leverages the GOV.UK frontend design system adapted for Slovak government use. The HTML and CSS are valid and structured with accessibility in mind, including skip links and ARIA attributes. Performance is moderate, with asynchronous script loading and deferred execution. Mobile optimization is good, with responsive layouts and appropriate input controls. The site uses a custom CAPTCHA widget (Altcha) for bot mitigation. No common CMS was detected, indicating a custom government platform. Hosting details are not explicit but likely government infrastructure. SEO is basic with meta viewport and title tags but lacks Open Graph or JSON-LD structured data. Overall, the technical implementation is solid but could be enhanced with richer metadata and security headers.
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.
