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

Seintillo s.r.o. is a professional insurance brokerage company based in the Czech Republic, offering a wide range of insurance and risk management services. As a member of the RENOMIA NETWORK and part of the RENOMIA GROUP, it benefits from a strong market position within Central and Eastern Europe. The company targets clients seeking personalized insurance solutions and claims handling support, leveraging its affiliation with a leading insurance brokerage group to provide comprehensive offerings including international services. Technically, the website is built on modern frameworks such as Next.js and React, with integrations for analytics (Microsoft Clarity, Google Tag Manager) and security (Google reCAPTCHA Enterprise). The site is well-optimized for performance, mobile responsiveness, and SEO, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS, employs security headers, and uses consent mechanisms for cookies, indicating good security hygiene. However, it lacks publicly available security policies or incident response information, which could be improved to enhance trust and compliance. Overall, the website presents a professional and trustworthy front for the business, though the absence of WHOIS data and explicit security documentation slightly reduces the confidence level. Strategic improvements in transparency and security disclosures are recommended to strengthen the company's digital trustworthiness.

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.

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

Seintillo s.r.o. operates in the finance sector, specifically insurance brokerage and risk management. Its competitive advantage lies in its membership in the RENOMIA NETWORK and affiliation with RENOMIA GROUP, providing access to extensive product offerings and market reach. The business model focuses on personalized client service, claims support, and international insurance solutions. The company targets both individual and corporate clients in the Czech Republic and abroad. Growth indicators include active content updates and integration with a large insurance group. The partnership ecosystem is strong, with clear links to RENOMIA GROUP and related domains. The company's operations appear stable and professionally managed, with a focus on quality service delivery.

Security posture

The website demonstrates a good security posture with HTTPS enforcement, modern security headers, and use of Google reCAPTCHA Enterprise to protect forms. Cookie consent is implemented, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response plans, or vulnerability disclosure mechanisms indicates room for improvement in transparency and preparedness. There is no visible security.txt or DPO contact information. Overall, the security maturity is moderate to good, suitable for the business type but could be enhanced with formal documentation and communication of security practices.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and client trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear contact details for a Data Protection Officer or privacy contact to support GDPR compliance.
  4. Regularly review and update privacy and cookie policies to reflect evolving regulations and best practices.
  5. Enhance website accessibility features and conduct periodic security audits to maintain high security standards.

Technical notes

Notes

The website is built using Next.js and React, indicating a modern and scalable architecture. It integrates analytics tools such as Microsoft Clarity and Google Tag Manager for user behavior tracking and performance monitoring. Google reCAPTCHA Enterprise is used for bot protection on forms. The site is well-optimized for mobile devices and SEO, with appropriate meta tags and Open Graph data. Hosting details are not explicitly identified, but the use of Google Cloud Storage for assets suggests cloud hosting. Performance is fast with efficient resource loading. The technical stack is current and supports a professional user experience, though hosting provider transparency could be improved.
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.
