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

10 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

  2. Security headers

    • 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

The company operates primarily in the technology sector with extensions into energy and education. Their business model is service-oriented, offering comprehensive IT and accounting solutions including ERP systems, electrical installations, and training courses. They maintain a diversified portfolio including online sales via their own e-shop. The presence of partner logos such as Microsoft and Solitea indicates strong industry relationships. Customer testimonials and a history dating back to 1999 suggest market stability and growth. The company targets small to medium businesses and individuals in the Czech Republic, leveraging digital channels and direct contact forms for lead generation. Their strategic partnerships and service breadth provide competitive advantages in their regional market.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA v3 on contact forms, and honeypot anti-spam measures. Tracking and analytics are implemented responsibly with cookie consent mechanisms. However, the absence of explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of publicly available WHOIS data limits external trust verification but does not indicate immediate risk. Overall, the site aligns well with common security best practices for business websites.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to enhance security.
  2. Regularly update WordPress core and plugins to mitigate vulnerabilities.
  3. Consider publishing a security policy or incident response contact information to improve transparency.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Seek to publish WHOIS data or domain registration details to improve domain trustworthiness.

Technical notes

Notes

The website is built on WordPress 6.8.2 with jQuery and uses modern JavaScript libraries such as Masonry for layout. It integrates multiple analytics and marketing tools including Google Analytics, Google Tag Manager, Facebook Pixel, and Microsoft Clarity. The site is mobile optimized with responsive images and CSS. Performance is moderate with asynchronous loading of scripts and deferred emoji support. The contact form uses Contact Form 7 with reCAPTCHA v3 and honeypot anti-spam. SEO is supported by proper meta tags and Open Graph data. No hosting provider information was detected. Overall, the technical implementation is solid with room for security header improvements 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.
