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

The website parc4u.cz is a Czech energy service platform focused on simplifying the process of switching energy suppliers for electricity and gas. Founded around 2019, it targets general consumers in the Czech Republic seeking fair energy prices without hidden fees. The site offers services that reduce paperwork and physical visits to offices, positioning itself as a convenient digital solution in the energy sector. Technically, the website employs modern JavaScript frameworks, likely Angular, and integrates analytics tools such as Google Tag Manager and a proprietary SAnalytics system. The site is mobile-optimized and presents a professional design with clear navigation, although accessibility features are basic. Security posture is moderate; HTTPS is implied but no explicit security headers or policies are detected, and no privacy or cookie policies are found, indicating gaps in compliance. The domain registration is consistent with the business age and sector, supporting legitimacy. Overall, the site is functional and professional but requires improvements in privacy compliance and security best practices to enhance trust and regulatory adherence.

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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      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

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

Parc4u.cz operates in the energy sector, providing a digital platform for consumers to switch electricity and gas suppliers easily. Its business model revolves around simplifying contract management and offering transparent pricing. The target market is Czech residential and possibly small business consumers. The company appears to be small-sized, founded in 2019, with no publicly disclosed parent or subsidiary companies. The platform leverages partnerships with energy suppliers, although no partner domains are explicitly identified. The use of advanced web technologies and analytics indicates a focus on digital engagement and customer experience. However, the absence of detailed contact information and compliance documentation may limit customer trust and regulatory confidence. Growth potential exists if compliance and security are enhanced, alongside clearer business transparency.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is presumably enabled, but no security headers such as Content-Security-Policy, X-Frame-Options, or Strict-Transport-Security are detected, which are critical for mitigating common web attacks. No explicit security policies or incident response contacts are provided, and no vulnerability disclosure or security.txt files are found. The forms and data collection mechanisms are not fully detailed, raising concerns about input validation and secure data handling. Analytics scripts are present without visible consent mechanisms, potentially conflicting with GDPR requirements. The lack of privacy and cookie policies further highlights compliance gaps. Overall, while no critical vulnerabilities are evident from the HTML content, the site would benefit from implementing comprehensive security headers, privacy compliance measures, and incident response readiness to strengthen its security posture.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with explicit user consent mechanisms.
  2. Add standard security headers (CSP, X-Frame-Options, X-Content-Type-Options, HSTS) to enhance protection against common web threats.
  3. Provide clear contact information including security incident and data protection officer contacts to improve transparency and compliance.
  4. Conduct a security audit of all forms and data inputs to ensure secure handling and validation.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine ranking.

Technical notes

Notes

The website uses a modern JavaScript framework, likely Angular, supported by asynchronous loading of analytics and tracking scripts including Google Tag Manager and a proprietary SAnalytics platform. The presence of Owl Carousel indicates interactive UI components. The site is mobile-optimized with responsive design and uses standard meta tags for SEO. However, no CMS or hosting provider information is explicitly found. Performance appears moderate with no evident blocking scripts. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. The lack of security headers and privacy compliance features indicates technical debt in security and regulatory adherence. Overall, the technical infrastructure supports a functional and user-friendly platform but requires modernization in security and compliance aspects.
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.
