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

C.E.I.S. CZ is a Czech Republic-based company specializing in energy consulting, project design, and engineering services with over 20 years of experience. Their offerings include energy audits, building energy performance certifications, emission measurements, and comprehensive project management services including subsidy and public procurement management. The website targets businesses and public entities seeking to improve energy efficiency and comply with regulatory requirements. Technically, the website employs modern frontend technologies such as Bootstrap and Google Fonts, and integrates Google Analytics for visitor tracking. The site is mobile-optimized with a clear navigation structure and a cookie consent mechanism, indicating a moderate level of digital maturity. Security posture is adequate with HTTPS implied, but lacks explicit security headers and detailed security policies. WHOIS data is unavailable, likely due to privacy protection, which slightly impacts trust but does not detract significantly from the professional presentation. Overall, the website is functional, professional, and provides relevant business information with moderate privacy compliance and security measures.

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

8 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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 solid position in the Czech energy consulting and engineering market, leveraging over two decades of experience. Their business model focuses on providing specialized services that combine technical expertise with regulatory compliance support, including subsidy management and public procurement. The target customer segments are primarily businesses and public sector entities requiring energy efficiency improvements and project engineering. The lack of visible contact details and social media presence may limit direct customer engagement but the comprehensive service offerings and clear website structure support business credibility. The use of Google Analytics and cookie consent indicates awareness of digital marketing and privacy regulations. No evident partnerships or subsidiaries are identified from the website content.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is used, ensuring encrypted communication, and a cookie consent banner is implemented to comply with privacy regulations. However, the absence of HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No explicit security policies or incident response contacts are provided, which could hinder transparency and trust. No forms or input fields are present on the homepage, reducing attack surface, but also limiting user interaction. The use of third-party scripts like Google Analytics and Cookie Bar requires ongoing monitoring for vulnerabilities. Overall, the security posture is adequate but could be improved with additional headers, policies, and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to enhance protection against web attacks.
  2. Publish clear security and incident response policies on the website to improve transparency and user trust.
  3. Add explicit contact information including company emails and phone numbers to facilitate communication and improve business credibility.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities and ensure compliance with privacy regulations.
  5. Consider adding structured data (JSON-LD) and Open Graph tags to improve SEO and social media sharing capabilities.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design, Google Fonts for typography, and FontAwesome for icons. Cookie consent is managed via a third-party JavaScript library, and Google Analytics is integrated for visitor tracking. The site is mobile-optimized with a clear navigation menu and well-structured content sections. No CMS or backend technologies are detectable from the HTML source. Performance appears moderate with no obvious heavy resources or blocking scripts. Accessibility features are basic but could be enhanced. SEO optimization is basic with meta tags present but no structured data. The absence of security headers and WHOIS transparency are technical risks that should be addressed to improve overall site robustness and trustworthiness.
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.
