SPP CZ, a.s. is a major energy supplier operating primarily in the Czech Republic and Slovakia, serving approximately 1.5 million customers including households, small businesses, and large enterprises. The company offers gas and electricity supply services with an emphasis on competitive pricing, transparency, and customer convenience through online tools such as savings calculators and contract management. The website reflects a well-structured digital presence with clear navigation and professional branding consistent with a large energy sector player. Technically, the website employs modern tracking and analytics tools including Google Tag Manager, Google Analytics, and Cookiebot for consent management, indicating a mature digital infrastructure. The site is mobile-optimized and SEO-friendly, though some accessibility features could be improved. Security posture is generally good with HTTPS enforced and form validation implemented, but lacks explicit security headers and published security policies. The absence of WHOIS registration data is a notable gap, reducing trustworthiness from a domain legitimacy perspective. However, the website content and business information strongly suggest a legitimate and established company. No signs of malicious content or security vulnerabilities were detected in the provided data. Overall, the site demonstrates a solid business and technical foundation with room for enhanced transparency and security documentation.

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

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

SPP CZ operates in the energy sector as a key supplier of gas and electricity in the Czech and Slovak markets. Its competitive advantage lies in its large customer base, transparent pricing, and comprehensive online services that simplify customer interactions. The business model focuses on B2C and B2B segments, including large consumers. The company maintains subsidiaries and related entities to support storage and charitable activities. Marketing efforts leverage multiple digital channels and tracking tools, indicating a data-driven approach to customer engagement. Growth indicators include extensive online content, active social media presence, and customer-centric tools. Strategic partnerships and subsidiaries enhance market reach and service offerings.

Security posture

The website enforces HTTPS and uses cookie consent management to comply with privacy regulations. Form inputs have client-side validation to reduce input errors and potential injection risks. However, the absence of visible security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web attacks. There is no publicly available security policy or incident response contact information, which limits transparency and preparedness perception. No vulnerability disclosures or security.txt files were found. Overall, the security posture is moderate with good baseline protections but lacking in advanced security communication and headers.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Improve accessibility features to meet higher standards for all users.
  5. Verify and update WHOIS registration data to improve domain trust and legitimacy.

Technical notes

Notes

The website uses a modern tech stack with Google Tag Manager, Google Analytics, and Cookiebot for analytics and consent management. The presence of slick slider and font preloading indicates attention to user experience and performance. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. However, no CMS or hosting provider information was detected. Performance is moderate with potential for improvement in accessibility and security headers. The site uses multiple external domains for analytics and social media integration, which are well managed with consent mechanisms.
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.
