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

DTEK is a leading private investor and operator in the Ukrainian energy sector, positioning itself as a pan-European energy group focused on sustainable and resilient energy solutions. The company targets energy sector stakeholders, investors, and European markets, offering services in energy production and investment. The website reflects a large, established enterprise with a founding date in 2000 and a strong market position in Ukraine. Technically, the website employs modern analytics and consent management tools such as Google Analytics, Google Tag Manager, and Cookiebot, indicating a mature digital infrastructure. The site is mobile-optimized and presents good SEO and accessibility features, although some accessibility aspects could be improved. Security-wise, the site uses HTTPS and domain transfer protections but lacks DNSSEC and security headers, which are recommended for enhanced security. Privacy compliance is partially addressed through a cookie consent mechanism, but explicit privacy policies and terms of service are not clearly found, representing an area for improvement. Overall, the website is professional and trustworthy, with room to enhance privacy and security transparency.

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

4 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 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

DTEK operates as a major private energy investor in Ukraine, with a business model centered on energy production and sustainable investments. The company leverages partnerships, such as with SCM Group (indicated by the Trust Line link), to strengthen its market presence. The website's content and structured data emphasize its leadership and transformation into a pan-European energy group, targeting investors and energy sector participants. The use of multiple social media channels and modern marketing tools suggests active engagement with stakeholders and a focus on brand visibility. The domain's long history supports the company's established market position. However, the absence of detailed legal and compliance documents on the website may limit transparency for some stakeholders.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and domain transfer protections in place. The use of Cookiebot for consent management and Google Tag Manager for analytics is standard practice. However, the lack of DNSSEC and absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduce the overall security robustness. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not provide explicit incident response or security policy information, which could be improved to enhance trust and readiness. Overall, the security posture is adequate but could benefit from implementing recommended security headers and publishing security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service documents accessible from the website.
  3. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information for a Data Protection Officer or privacy contact.
  5. Publish an incident response policy or security contact information to improve transparency and readiness.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics, Google Tag Manager, Microsoft Clarity, and Cookiebot for consent management. The HTML and CSS appear valid and the site is mobile-optimized with good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with asynchronous loading of scripts to improve speed. No CMS or hosting provider was explicitly detected. Accessibility features are basic but present. The site uses multiple external domains for analytics, social media, and consent management, all reputable. There is an opportunity to improve technical security by enabling DNSSEC and adding security headers. Overall, the technical infrastructure supports a professional and functional corporate website.
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.
