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

ŠKO-ENERGO is a financially stable energy company providing comprehensive energy solutions primarily for ŠKODA AUTO and the city of Mladá Boleslav. The company focuses on producing and distributing environmentally friendly energy using carbon-free technologies, offering industrial energy services and energy consumption reduction consulting. The website reflects a professional corporate presence with clear branding and a focus on compliance and privacy. Technically, the site employs modern tools such as Google Tag Manager, Cookiebot for consent management, and reCAPTCHA for security, indicating a mature digital infrastructure. Security posture is strong with HTTPS enforced and cookie consent mechanisms in place, though some security headers could be improved. Overall, the site is well-structured, mobile-optimized, and compliant with GDPR requirements, though WHOIS data is unavailable, likely due to privacy protection. The absence of direct contact emails or phone numbers on the main site suggests contact is managed via forms or dedicated pages.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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

ŠKO-ENERGO holds a key market position as the main energy supplier for a major automotive manufacturer and a municipal client, indicating a stable and significant business model focused on industrial energy production and distribution. The company leverages partnerships and maintains a career portal, suggesting growth and talent acquisition focus. The business model is B2B with emphasis on sustainability and innovation in energy technologies. The website's content and structure support this positioning, with detailed sections on technology, activities, and compliance. The use of third-party analytics and marketing tools indicates an active approach to user engagement and market analysis.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and integration of reCAPTCHA to prevent automated abuse. Cookie consent is managed via Cookiebot, supporting GDPR compliance. However, the absence of explicit security headers like Content-Security-Policy and lack of a security.txt file or incident response contacts are areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The site uses trusted third-party services for analytics and marketing, which should be regularly audited to maintain security. Overall, the security maturity is good but can be enhanced with additional headers and transparency measures.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  3. Add explicit incident response contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and readiness.
  4. Enhance accessibility features to improve compliance with accessibility standards and user experience for all visitors.
  5. Regularly review and audit third-party scripts and analytics tools to mitigate risks from external dependencies.

Technical notes

Notes

The website uses a modern tech stack including JavaScript, Google Tag Manager, Cookiebot for cookie management, and Google reCAPTCHA for bot protection. The site is mobile-optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate, with potential for improvement in loading speed and accessibility. The lack of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports the business needs but could benefit from enhanced security headers and performance optimizations.
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.
