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.

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

Firmy.cz operates as an essential online platform in the Czech market, providing a trusted business directory service that supports local commerce and consumer decision-making. Its integration with Seznam.cz, a major Czech internet company, offers competitive advantages including access to a large user base and advanced advertising technologies. The business model revolves around listing services, user-generated reviews, and marketplace offers, generating revenue through advertising and premium listings. The platform serves a broad audience including small to large businesses and general consumers. Growth indicators include extensive categorized listings and active user engagement through reviews. The partnership ecosystem includes advertising networks and analytics providers, enhancing monetization and user insights. Strategic observations suggest continued focus on expanding service categories and improving user personalization to maintain market leadership.

Security posture

Firmy.cz demonstrates a mature security posture with enforced HTTPS and use of secure cookies. While explicit security headers such as Content-Security-Policy and X-Frame-Options are not explicitly confirmed, the site shows no signs of exposed sensitive data or vulnerable libraries. The absence of publicly available security policies or incident response contacts indicates an area for improvement in transparency and readiness. Compliance with GDPR is evident through privacy and cookie policies, but further disclosures on data retention and breach notification would strengthen trust. Overall, the security maturity is good but could benefit from enhanced documentation and explicit security controls disclosure.

Recommendations

  1. Implement and publicly disclose a comprehensive security policy and incident response plan.
  2. Ensure all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options) are configured and documented.
  3. Enhance accessibility features to meet WCAG standards for broader compliance.
  4. Provide clear and verified company contact information to improve business credibility.
  5. Regularly audit third-party scripts and advertising networks to minimize privacy risks.

  2. Content is rich with business listings, user reviews, and categorized offers.

Technical notes

Notes

The website uses a modern JavaScript-based frontend, likely React or similar, with custom widgets integrated from Seznam.cz services. Performance is moderate with good mobile optimization and responsive design. SEO is well addressed with proper meta tags, Open Graph, and structured JSON-LD data for local businesses. The site uses multiple external domains for advertising and analytics, which may introduce complexity in privacy management. Hosting details are not explicitly identified, but the infrastructure appears robust given the integration with Seznam.cz. Technical risks include reliance on multiple third-party ad networks and potential gaps in security header implementation. Opportunities exist to modernize accessibility and enhance security transparency.
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.
