Rentea penzijní společnost, a.s. is a Czech licensed pension company specializing in supplementary pension savings with state contributions and loyalty bonuses. The company positions itself as a provider of long-term pension savings with a focus on high returns and low management costs, leveraging investment tools from BlackRock. The website is professionally designed, mobile-optimized, and provides comprehensive information about pension products, regulatory compliance, and customer service options. Technical infrastructure includes modern JavaScript frameworks and third-party integrations such as Google Tag Manager and Daktela chat for customer support. Security posture is strong with HTTPS and secure forms, though explicit security headers and incident response information are absent.

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

4 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, LinkedIn

      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

Rentea operates in the Czech financial sector, focusing on supplementary pension savings products. It benefits from partnerships within the Partners financial group ecosystem, including investment, insurance, and banking services. The business model centers on pension fund management with state incentives and personalized advisory services. The target market is individuals seeking pension savings solutions with state support. The company emphasizes trust through regulatory compliance and transparent bonus schemes. Growth potential is supported by evolving pension regulations and increasing awareness of supplementary pension products. The website's integration with multiple partner domains indicates a collaborative ecosystem enhancing service offerings and market reach.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement, secure input validation, and cookie consent compliance. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap that could be addressed to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. Overall, the security maturity is good but could be improved by adopting additional best practices and publishing relevant security documentation.

Recommendations

  1. Implement and publish security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Consider creating and hosting a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance WHOIS transparency by ensuring domain registration data is publicly available or justified if privacy protected.
  5. Maintain and regularly update privacy and cookie policies to comply with evolving regulations and best practices.

Technical notes

Notes

The website uses a modern JavaScript stack including Stimulus.js for frontend interactivity, Swup.js for page transitions, and Locomotive Scroll for smooth scrolling effects. LazySizes is used for image lazy loading, improving performance. Google Tag Manager is integrated for analytics and marketing tracking. The site is mobile-optimized with responsive design and accessibility considerations. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML content. Performance is moderate with room for optimization. The technical implementation reflects a contemporary approach suitable for a financial services website, balancing user experience and functionality.
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.
