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

Innogy.cz operates as a major energy provider in the Czech Republic, serving over 1.7 million customers with electricity, natural gas, and related services. The website premium.innogy.cz focuses on the innogy Premium customer loyalty program, offering discounts and monthly contests to enhance customer engagement. The company positions itself as a leading energy supplier with a large workforce and a broad market presence. Technically, the website employs modern JavaScript libraries, Google Tag Manager, and Cookiebot for consent management, reflecting a mature digital infrastructure. Security posture is strong with HTTPS enforcement and bot protection via Cloudflare Turnstile, though explicit security headers and vulnerability disclosure mechanisms are absent. Privacy compliance is well addressed with clear policies and consent banners. Overall, the site is professional, user-friendly, and trustworthy, but the lack of WHOIS data introduces some uncertainty about domain registration legitimacy.

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

5 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube, Cloudflare

      What to do: Document all third-party data sharing in your privacy policy

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Innogy's market position as a large energy supplier in the Czech Republic is supported by its extensive customer base and employee count. The innogy Premium program adds value through partner discounts across various sectors such as electronics, home goods, and entertainment, indicating a diversified partnership ecosystem. The business model leverages customer loyalty and cross-promotional offers to maintain competitive advantage. The website's integration with partner domains and social media channels suggests a well-established digital marketing strategy. However, the absence of visible direct contact emails or phone numbers on the main page may limit immediate customer support accessibility. The company appears to focus on brand consistency and customer engagement through contests and benefits.

Security posture

The website demonstrates a solid security foundation with HTTPS and bot mitigation via Cloudflare Turnstile captcha. Cookie consent is managed comprehensively with Cookiebot, allowing granular user control, which supports GDPR compliance. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options could expose the site to certain web-based attacks. No security.txt or vulnerability disclosure policy is present, which limits transparency and incident response readiness. No exposed sensitive data or vulnerable libraries were detected in the analysis. Overall, the security posture is good but could be improved by adopting additional HTTP security headers and publishing incident response information.

Recommendations

  1. Implement and enforce HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information or security.txt file to improve transparency and facilitate vulnerability reporting.
  3. Verify and update WHOIS domain registration information to ensure transparency and trustworthiness of domain ownership.
  4. Enhance contact information visibility by including verified company emails and phone numbers on the website for improved customer support.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced and maintain compliance with evolving privacy regulations.

Key observations

  1. Website is fully accessible with rich content and interactive elements.
  2. Strong cookie consent management and privacy compliance.
  3. No visible contact emails or phone numbers on main page; contact available via contact page.
  4. No explicit security.txt or vulnerability disclosure found.
  5. WHOIS data unavailable, which reduces trust score.
  6. Use of modern JavaScript libraries and Google Tag Manager indicates professional digital infrastructure.
Technical notes

Notes

The website uses a modern tech stack including jQuery 3.7.1, Google Tag Manager, Cookiebot for consent management, and Splide for carousel functionality. Hosting appears to be behind Cloudflare, providing CDN and security benefits. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA roles. Performance is moderate with preloading of fonts and scripts to improve load times. SEO is supported by proper meta tags, Open Graph, and Twitter card metadata. No CMS was explicitly detected. The technical implementation is solid but could benefit from additional security headers and enhanced domain registration transparency.
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.
