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. Network security

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

    • Critical

      Critical Service Exposed: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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 · 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 company operates in the energy sector, focusing on renewable and efficient energy management solutions for commercial and institutional clients. Their business model is B2B, offering technology deployment, energy supply, and compliance services. Partnerships with established Czech energy companies and technical universities enhance their market credibility. The company is relatively new, founded in 2023, and targets medium to large enterprises seeking sustainable energy solutions. Their website content and branding are consistent, reflecting a professional image. Revenue streams likely include technology sales, energy supply contracts, and service agreements. The partnership ecosystem includes CEZ, CEPS, CVUT, PRE, and EGD, indicating strong industry ties. Growth indicators include recent projects and a focus on innovative energy technologies.

Security posture

The website enforces HTTPS and uses cookie consent mechanisms aligned with GDPR requirements, indicating a baseline security maturity. However, the absence of DNSSEC and security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options suggests room for improvement. No incident response or security policy information is publicly available, which could hinder transparency in case of security events. The use of third-party scripts like Google Analytics and Lightwidget introduces potential risks if not regularly audited. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but would benefit from enhanced security controls and documented policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  3. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance accessibility features and provide a terms of service page to improve compliance and user trust.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, OreJime for cookie consent management, Lenis for smooth scrolling, Swiper for sliders, and Three.js with Vanta.js for interactive visual effects. Google Analytics is integrated for user behavior tracking with consent-based activation. Hosting is managed through WEDOS Internet with DNS services via Cloudflare, though DNSSEC is not enabled. The site is mobile-optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate, with some parallax and animation effects that may impact load times. No CMS was detected, suggesting a custom or static site architecture. Technical debt appears low but could be improved with enhanced security headers and accessibility compliance.
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.
