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.

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

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 niche position in the manufacturing sector, specializing in vacuum electron tubes used in RF generators for industrial applications such as laser cutting, heating, and welding. Their business model is focused on supplying both products and accessories, supported by detailed product datasheets and a multilingual approach to reach broader markets. The presence of a partner IT company (jktech.cz) suggests a collaborative ecosystem for digital solutions. The website's clear contact information and product offerings indicate a transparent and customer-focused approach. However, the lack of WHOIS data and limited social media presence may impact broader market trust and visibility. The company appears to be a small-sized entity with a specialized product portfolio, targeting industrial clients requiring high-quality electron tubes.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and secure form handling. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contacts indicates limited transparency in security governance. GDPR compliance is partial, with no cookie consent mechanism visible, which may pose compliance risks. The site would benefit from implementing additional security headers, cookie consent banners, and publishing incident response information to enhance trust and compliance.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Add a cookie consent banner and privacy policy updates to ensure GDPR compliance and improve user trust.
  3. Regularly update WordPress core, themes, and plugins to minimize vulnerabilities from outdated software.
  4. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  5. Review and assess external links, especially to domains like konrltd.ru, for potential security or reputational risks.

Technical notes

Notes

The website is built on a modern WordPress CMS platform with WooCommerce for e-commerce capabilities. It uses Themify Ultra theme and several JavaScript libraries including jQuery, Swiper.js, and Builder Slider Pro for enhanced UI/UX. The site is multilingual via TranslatePress, indicating readiness for international visitors. Performance is moderate with preloading and prefetching optimizations. Mobile responsiveness is good, but accessibility features are basic. No hosting provider details were found. The site lacks advanced security headers and cookie consent mechanisms, which are technical gaps. Overall, the technical infrastructure is solid for a small manufacturing business website but can be improved in security and privacy compliance aspects.
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.
