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

3D Návody is a Czech Republic based organization focused on providing interactive 3D guides and educational resources in the renewable energy sector, specifically photovoltaic systems and other renewable energy sources. The website serves professionals and trainees aiming to increase their expertise through online interactive content, mobile applications, and access to specialized databases. The business is relatively new, with domain registration in late 2024, aligning with the launch of the platform. The company operates under the legal entity Komora obnovitelných zdrojů energie, z.s., indicating a formal organizational structure within the energy sector. Technically, the website is built on a modern WordPress CMS platform using Elementor for page building and Yoast SEO for optimization. It employs standard web technologies including jQuery and integrates Google Tag Manager for analytics. The site is mobile optimized and demonstrates good SEO practices, although accessibility features could be improved. Performance is moderate, with caching plugins in use. From a security perspective, the site uses HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers and formal security policies or incident response contacts. Privacy compliance is minimal, with no visible privacy or cookie policies or consent mechanisms, which is a gap for GDPR compliance. No vulnerabilities or suspicious patterns were detected in the content or WHOIS data. Overall, the website presents a professional and trustworthy platform for renewable energy education in the Czech market. Strategic improvements in privacy compliance, security headers, and incident response documentation would enhance trust and regulatory adherence.

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

11 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

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 · found on this site
  • 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 business targets a niche market of renewable energy professionals and trainees in the Czech Republic, offering specialized 3D interactive guides and databases for photovoltaic and other renewable energy technologies. Its business model revolves around educational content delivery, mobile applications, and access to curated databases, possibly monetized through training courses and partnerships. The presence of partner domains hosting databases and training content indicates a collaborative ecosystem. The company is positioned as a specialized knowledge provider with a focus on increasing qualifications in the energy sector. Growth potential exists through expanding educational offerings and enhancing digital presence. The lack of extensive contact details and certifications suggests a small but focused operation.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, which is mandatory for secure communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No explicit security or incident response policies are published, and no dedicated security contact channels are provided. The use of up-to-date WordPress and plugins reduces vulnerability risks, but continuous monitoring and patching are essential. Privacy compliance is weak, with no cookie consent or privacy policy visible, posing regulatory risks under GDPR. Overall, the security posture is adequate for a small educational site but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR-compliant consent mechanisms.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to improve protection against web vulnerabilities.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Establish and display incident response contact information, including security or abuse email addresses.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on WordPress 6.6 with Elementor 3.30.3, leveraging popular plugins such as Yoast SEO and LiteSpeed Cache for performance and SEO optimization. It uses jQuery 3.7.1 and integrates Google Tag Manager for analytics. The site loads external resources from Google Fonts and uses Swiper.js and Magnific Popup for UI components. The technical infrastructure is modern and standard for small to medium WordPress sites. Performance is moderate, with caching enabled but potential for further optimization. Mobile responsiveness is good, and SEO metadata is well implemented. Technical risks include reliance on third-party plugins which require regular updates and the absence of advanced security headers. Hosting provider details are not explicitly identified from the data.
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.
