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

10 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

      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

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 website operates as a free online crossword dictionary serving a niche market of Czech language puzzle solvers. Its business model relies on advertising revenue, with no evident e-commerce or subscription services. The site offers search functionality, alphabetical word lists, and categorized hints, catering to both casual and expert users. The presence of a Slovak partner site suggests a regional partnership strategy. The lack of detailed company information and physical contact details indicates a small-scale operation, likely run by individuals or a small team. Growth potential exists through content expansion and the planned addition of interactive crossword puzzles. The partnership with krížovkársky slovník slovensky indicates cross-border collaboration within the puzzle niche.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which could mitigate common web vulnerabilities. No sensitive data exposure or vulnerable libraries were detected. The site uses secure form inputs but does not provide a security policy or incident response contact channels, limiting transparency in security management. Cookie consent is implemented, supporting GDPR compliance to some extent. Overall, the security maturity is moderate but could be improved by adopting additional security best practices and formalizing security policies.

Recommendations

  1. Implement comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish a security.txt file and provide incident response contact information to improve transparency and readiness.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built with standard web technologies and integrates Google services for analytics and advertising. The HTML and CSS are valid and the site is mobile responsive with good navigation clarity. Hosting is provided by Wedos, a reputable Czech provider, consistent with the domain registration. Performance is moderate, with room for optimization. No CMS or advanced frameworks were detected, indicating a custom or lightweight implementation. The site uses JavaScript for search suggestions and cookie consent management. Technical risks include lack of security headers and limited privacy documentation, which could impact compliance and security posture. Opportunities exist to modernize the tech stack and improve performance and security.
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.
