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

Innogy Česká republika a.s. is a large energy company operating in the Czech Republic, providing gas and electricity supply alongside value-added services such as gas boiler servicing. The website offers a subscription-based boiler maintenance service aimed at domestic customers, emphasizing safety, efficiency, and cost savings. The company maintains a strong market position with diversified energy-related offerings and a customer portal named innosvět for service management. Technically, the website employs modern JavaScript frameworks and integrates third-party services like Google Tag Manager and Cookiebot for analytics and privacy compliance. The site is well-optimized for mobile devices, accessible, and SEO-friendly, with structured data enhancing search engine understanding. Performance is moderate, with asynchronous loading of scripts and preloading of fonts. Security posture is strong with HTTPS enforced, multiple security headers present, and no visible vulnerabilities or exposed sensitive data. Privacy compliance is robust, featuring a comprehensive cookie consent mechanism and a clear privacy policy. However, the absence of a dedicated security policy or incident response contact reduces transparency in security governance. Overall, the website is professional, trustworthy, and secure, with minor gaps in explicit security disclosures. The lack of WHOIS data limits domain registration transparency but does not detract from the site's legitimacy based on content and business information.

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, LinkedIn, 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

      • 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 operates in the energy sector, targeting residential customers primarily in the Czech Republic. Their business model combines energy supply with ancillary services such as boiler maintenance, home assistance, and insurance products, generating recurring revenue streams. The company leverages digital channels including a customer portal and online service ordering to enhance customer engagement and operational efficiency. Partnerships with related domains for photovoltaic energy, electric mobility, and CNG services indicate a broad ecosystem approach. The brand is well-established with consistent messaging and strong trust signals, positioning Innogy as a key player in the Czech energy market.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no detected vulnerabilities in the analyzed content. Privacy compliance is evident through cookie consent and a detailed privacy policy. However, the absence of a published security policy, incident response procedures, or vulnerability disclosure program suggests room for improvement in transparency and readiness. The use of third-party scripts is managed but should be regularly audited to mitigate supply chain risks. Overall, the security measures align well with industry best practices for a commercial energy provider's web presence.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Provide clear incident response contact information to improve transparency and trust.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.
  5. Enhance WHOIS transparency if possible to improve domain registration trustworthiness.

Technical notes

Notes

The website uses modern web technologies including asynchronous JavaScript loading, Google Tag Manager for analytics, and Cookiebot for cookie consent management. Fonts are preloaded for performance optimization. The site is mobile-optimized and accessible, with semantic HTML and ARIA landmarks. Structured data in JSON-LD format improves SEO and enables rich search results. Hosting and CMS details are not explicitly identified, but the site appears professionally maintained with good performance. Opportunities exist to further improve performance metrics and to document technical infrastructure for 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.
