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

FLO Lokalizace netěsností s.r.o. is a specialized service provider in the Czech Republic focusing on leak localization, tightness testing, and flat roof inspections. The company positions itself as a trusted specialist with a long-standing tradition in the energy/building maintenance sector. Their website reflects a professional service-oriented business model targeting property owners and construction professionals seeking reliable roof inspection services. Technically, the website is built on WordPress using the Avada theme, enhanced with SEO and analytics tools such as Yoast SEO and Google Tag Manager. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, HTTPS is enabled and Google reCAPTCHA is implemented, but the absence of security headers and explicit privacy policies indicates room for improvement. The lack of WHOIS data reduces transparency and trust, although the social media presence and structured data support legitimacy. Overall, the website is functional and professional but would benefit from enhanced privacy compliance and security disclosures.

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

5 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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 operates in the energy/building maintenance sector, offering niche services in leak detection and roof tightness testing. Its market position is that of a specialized local expert with a focus on quality and reliability. The business model is service-based, targeting a defined customer segment in the Czech Republic. The website's content and social media links suggest active engagement with clients, although direct contact details are not prominently displayed. The absence of WHOIS data and privacy policies may impact customer trust and regulatory compliance. There is no evidence of partnerships or subsidiaries from the website data. Marketing relies on SEO and digital analytics, with moderate user tracking. The company appears to be a small-sized entity with a focused service portfolio.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is properly configured, and Google reCAPTCHA is used to protect forms from automated abuse. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap. No security.txt or vulnerability disclosure mechanisms are present, limiting transparency for security researchers. The missing WHOIS data raises concerns about domain registration legitimacy. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the site follows some best practices but requires improvements in security headers, policy disclosures, and domain transparency to enhance trust and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies clearly accessible on the website.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Verify and update WHOIS domain registration information to improve transparency and trust.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and security posture.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Avada theme, which provides a responsive and visually consistent design. SEO is enhanced via the Yoast SEO plugin, and analytics are managed through Google Tag Manager. The site loads a variety of Google Fonts and uses Google reCAPTCHA for form protection. Performance is moderate with no evident critical errors or broken elements. However, the site lacks advanced security headers and explicit privacy/legal pages. Hosting provider details are not discernible from the HTML content. The technical stack is standard for small to medium-sized service websites, with opportunities to improve security and compliance features.
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.
