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

      • 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 Česká republika a.s. leverages its digital presence to maintain strong market positioning in the Czech energy sector. The business model focuses on direct energy supply combined with digital customer engagement through the innosvět portal. Revenue streams include energy sales and value-added services such as contract management and consumption analytics. The target audience spans households and businesses in the Czech Republic. The company maintains partnerships and related service domains for photovoltaic solutions, e-mobility, and CNG fuel, indicating a diversified energy portfolio. Growth indicators include active online customer portals and mobile applications. The company demonstrates a mature digital ecosystem with integrated marketing and analytics tools.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive cookie consent management, and no exposed sensitive data in the HTML content. Use of third-party scripts is controlled, and no vulnerable libraries were detected. However, the absence of a publicly available security policy or incident response contact reduces transparency. GDPR compliance is evident through cookie consent and privacy policy presence. The site would benefit from publishing a vulnerability disclosure policy and explicit security framework adherence. Overall, the security maturity is high with room for improvement in transparency and incident readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and frameworks.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information for security issues.
  4. Regularly review and audit third-party scripts to mitigate supply chain risks.
  5. Enhance transparency around data retention and privacy practices.

The website uses a modern technology stack including Google Tag Manager for analytics and marketing, Cookiebot for GDPR-compliant cookie management, and Mluvii for customer chat support. The site is responsive and optimized for mobile devices with good accessibility features. Performance is moderate with room for optimization. The CMS or hosting provider is not explicitly identified. The site employs SVG icons and structured data (JSON-LD) for SEO and rich snippets. Technical risks are minimal, but continuous monitoring of third-party dependencies is recommended to maintain security and performance.
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.
