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

The company holds a strong market position as a leading supplier of web services for public administration in the Czech Republic. Their business model focuses on delivering comprehensive web solutions, including proprietary CMS platforms like vismo 6, targeting municipalities and government bodies. The company benefits from long-term client relationships, evidenced by managing thousands of websites and a significant market share. Their competitive advantage lies in specialized knowledge of public sector requirements and legislative compliance. The presence of social media channels and regional representation indicates a broad operational footprint. The company does not publicly disclose certifications or incident response policies, which could be areas for future enhancement. Overall, WEBHOUSE s.r.o. demonstrates stable growth potential and a focused partnership ecosystem.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of Google reCAPTCHA v3 to mitigate automated abuse. Secure form handling includes anti-forgery tokens, reducing CSRF risks. However, explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident, representing an opportunity for hardening. No security or incident response policies are published, which limits transparency for vulnerability reporting and incident handling. The use of reputable third-party analytics and tracking tools is balanced with GDPR-compliant cookie consent mechanisms, indicating awareness of privacy regulations. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is good but could be improved with formalized policies and enhanced HTTP headers.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information to improve transparency and trust.
  2. Add HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Consider establishing a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party libraries and scripts to ensure no vulnerabilities are introduced via dependencies.
  5. Enhance documentation and visibility of data retention policies related to analytics and user data to strengthen privacy compliance.

Technical notes

Notes

The website uses a modern technology stack including Vue.js and Mustache.js for frontend rendering, supported by proprietary CMS technology (vismo 6). Integration with Google reCAPTCHA v3 and analytics tools like Google Analytics, Facebook Pixel, and Smartlook indicates a mature digital marketing and security approach. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and Open Graph data. Performance is moderate, with asynchronous loading of scripts and preconnect hints to optimize resource fetching. The absence of explicit hosting provider information limits full infrastructure assessment. Overall, the technical implementation is solid with room for improvement in security headers and formal documentation.
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.
