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.

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

Firmy.cz operates as an essential online directory service within the Czech Republic, targeting a broad audience including consumers looking for local services and businesses seeking visibility. Its business model revolves around providing verified company listings, user-generated reviews, and advertising opportunities. The platform benefits from its parent company Seznam.cz, a major Czech internet service provider, which supports its market position and infrastructure. Revenue streams likely include advertising, premium listings, and lead generation. The site covers multiple sectors such as real estate, hospitality, transportation, retail, and various services, indicating a diversified portfolio. The presence of detailed company profiles and integration with other Seznam services suggests a strong partnership ecosystem. Growth indicators include extensive content, regular updates, and user engagement through reviews. Strategic observations highlight the importance of maintaining data accuracy, enhancing privacy transparency, and expanding digital marketing capabilities.

Security posture

Firmy.cz demonstrates a solid security posture with mandatory HTTPS encryption and implementation of key security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security. The site avoids exposing sensitive information in its HTML content and uses secure forms for user interactions. Third-party scripts are present but appear to be from reputable sources, though continuous monitoring is recommended to mitigate supply chain risks. Privacy policies and cookie consent mechanisms align with GDPR requirements, indicating compliance maturity. However, the absence of a dedicated security policy or incident response contact information suggests room for improvement in transparency and readiness. No critical vulnerabilities or malware indicators were detected. Overall, the security maturity is good but could be enhanced by publishing explicit security and incident response documentation and conducting regular security audits.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and user data protection.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Regularly audit and update third-party scripts to minimize supply chain vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Increase transparency in cookie consent and data retention policies to strengthen privacy compliance.

Technical notes

Notes

The website is built on a modern JavaScript-based frontend with hydrated web components, leveraging APIs from Mapy.cz for mapping and Seznam.cz for login and other services. It uses Google Fonts and integrates multiple analytics and advertising scripts including Gemius and Google Tag Manager. The hosting appears to be managed by Seznam.cz, ensuring reliable infrastructure. Performance is moderate with room for optimization, especially in loading times and resource management. Mobile optimization is good, supporting responsive design and usability. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD data for local business listings. Accessibility is basic but could be improved with more ARIA attributes and keyboard navigation enhancements. Overall, the technical implementation is robust but could benefit from performance tuning and enhanced accessibility.
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.
