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

Flou.cz is a Czech Republic-based SaaS platform providing an intelligent information system tailored for small businesses, craftsmen, and sole proprietors (OSVČ). The platform centralizes management of offers, orders, invoices, contacts, and financial documents in a cloud environment accessible from multiple devices. Its business model focuses on subscription services with a free 30-day trial, targeting a niche market of small enterprises seeking to streamline administrative tasks. The website content is professionally presented in Czech, with clear navigation and consistent branding, supporting a trustworthy user experience. Technically, the website employs modern web technologies including Google Analytics for traffic analysis, Smartsupp Live Chat for customer support, and Google reCAPTCHA for bot protection. The site is responsive and optimized for mobile devices, though accessibility features are basic. Performance is moderate, with bundled CSS and JavaScript resources. Security best practices include HTTPS enforcement and cookie consent mechanisms, though HTTP security headers are not explicitly detected. From a security perspective, the site demonstrates a solid posture with encrypted communications and user privacy considerations. However, the absence of explicit incident response contacts and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The lack of WHOIS data limits domain registration trust analysis, but the professional presentation and contact information mitigate concerns. Overall, the site is low risk with good privacy compliance and business credibility. Strategically, Flou.cz should enhance its security headers, publish a security.txt file, and provide clearer incident response contacts to strengthen trust and compliance. Continued focus on accessibility and performance optimization will improve user experience and broaden market appeal.

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

Flou.cz occupies a specialized niche in the Czech small business software market, offering a comprehensive cloud-based administrative system for OSVČ and small firms. Its competitive advantage lies in simplicity, automation, and multi-entity account management, appealing to users with limited technical expertise. Revenue likely derives from subscription fees post-trial. The platform's integration of offers, orders, finance, and automation streamlines workflows, reducing administrative overhead. The company maintains a modest digital footprint with a professional website and active Facebook presence. Partnerships with Anything Studio for development indicate a collaborative ecosystem. Growth potential exists in expanding feature sets and enhancing compliance certifications. The absence of phone contact and physical address may limit trust for some users but is offset by clear email support and testimonials.

Security posture

The website demonstrates a mature security posture with HTTPS enforced site-wide, use of Google reCAPTCHA to prevent automated abuse, and a comprehensive cookie consent mechanism supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No explicit incident response or vulnerability disclosure information is provided, which could hinder timely reporting and remediation of security issues. The site does not publish a security.txt file, a modern best practice for transparency. Overall, the security posture is good but could be improved by implementing additional headers, incident response contacts, and formal vulnerability disclosure channels.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a security.txt file at the root domain to provide clear vulnerability disclosure and incident response contacts.
  3. Add explicit incident response contact information on the website, such as a security@ or abuse@ email address.
  4. Enhance accessibility features to meet recognized standards and improve usability for all users.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack with JavaScript-based analytics (Google Analytics), live chat (Smartsupp), and bot protection (Google reCAPTCHA). CSS and JavaScript resources are bundled for performance optimization. The site is responsive and mobile-friendly, supporting access from desktops, tablets, and smartphones. No CMS or hosting provider information is explicitly detected. Performance is moderate, with room for improvement in SEO and accessibility. The site lacks advanced security headers and formal vulnerability disclosure mechanisms. Overall, the technical infrastructure supports the business needs but could benefit from modernization in security and accessibility 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.
