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

Slovníky.cz is a Czech online dictionary and lexicon platform operated by the company Maxdorf, established in 1998. The website offers specialized lexicons, including medical dictionaries, and links to related services such as a bookstore and an encyclopedic club. The business targets general users seeking reference materials in Czech language, operating a niche content service with a small-scale business model. Technically, the site is built with basic HTML, CSS, and JavaScript, incorporating Google Analytics for visitor tracking. The infrastructure is hosted by REG-ZONER, a Czech hosting provider, and the domain is long-established, supporting business credibility. Security posture is moderate with HTTPS enabled but lacks modern security headers and privacy compliance mechanisms. No privacy or cookie policies are present, and no contact information is provided, which limits trust and compliance. Overall, the site is functional but could benefit from modernization and enhanced security and privacy practices.

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

9 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

      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

The company Maxdorf operates slovniky.cz as a specialized online dictionary and lexicon service, focusing on Czech language content including medical and small lexicons. The business model appears content-driven with ancillary e-commerce through linked bookstore sites. Market positioning is niche and localized with a stable presence since 1998. The ecosystem includes related domains under Maxdorf branding, indicating a small network of partner sites. Revenue streams likely include content access and bookstore sales. The absence of detailed contact or corporate information limits transparency but the domain age and consistent branding support legitimacy. Growth potential may be limited by basic technical implementation and lack of modern digital marketing or privacy compliance features.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, indicating limited security maturity. The use of Google Analytics without visible cookie consent mechanisms raises privacy compliance concerns under GDPR. No forms or input fields are present, reducing attack surface but also limiting user engagement. Overall, the security posture is functional but minimal, with significant room for improvement in compliance, transparency, and technical safeguards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance and consent mechanisms.
  2. Add security headers to enhance protection against common web vulnerabilities.
  3. Provide clear contact information including emails and phone numbers to improve trust and compliance.
  4. Establish a vulnerability disclosure policy and incident response contact channels.
  5. Modernize the website with improved mobile optimization, accessibility, and SEO best practices.

Technical notes

Notes

The website uses a simple technology stack consisting of HTML, CSS, and JavaScript, with Google Analytics for visitor tracking. The site is hosted by REG-ZONER, a Czech hosting provider, and uses HTTPS. The HTML includes legacy compatibility meta tags but no modern frameworks or CMS are detected, suggesting a static or custom-built site. Performance is moderate with no explicit indicators of optimization or caching. Mobile optimization and accessibility are basic, with no ARIA roles or advanced features detected. SEO is minimal with only basic meta tags and no structured data or Open Graph tags. The technical debt is moderate due to outdated practices and lack of modern security and privacy features, posing risks for future scalability and compliance.
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.
