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

RENOMIA, a. s. is a well-established insurance brokerage and risk management company based in the Czech Republic, offering a broad range of insurance solutions and consulting services to businesses, entrepreneurs, and municipalities. The company maintains a strong market position supported by client testimonials, industry awards, and a comprehensive service portfolio including international insurance services. The website is professionally designed, multilingual, and provides clear navigation and extensive content relevant to its target audience. Technically, the site uses modern web technologies and a proprietary CMS, with good mobile optimization and SEO practices. Security posture is solid with HTTPS and cookie consent mechanisms, though additional security headers and explicit security policies could enhance trust. The absence of WHOIS data is a limitation but does not detract from the overall legitimacy and professionalism observed. Strategic recommendations include improving security headers, publishing incident response contacts, and implementing vulnerability disclosure policies.

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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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 256-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

RENOMIA operates in multiple sectors including energy, transportation, real estate, healthcare, and manufacturing, positioning itself as a comprehensive risk management and insurance broker. Its business model focuses on providing tailored insurance solutions and claims management, supported by a network of subsidiaries and partner companies. The company targets medium to large enterprises and public sector clients, leveraging its expertise and international reach. The presence of multiple related domains and a strong social media footprint indicates a mature partnership ecosystem and active market engagement. The company’s awards and client references reinforce its competitive advantage and credibility in the Czech insurance market.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent compliant with GDPR, and no visible exposure of sensitive data. However, the lack of advanced security headers such as Content-Security-Policy and absence of a published security policy or incident response contact reduces transparency. No vulnerability disclosures or security.txt files were found, which could be improved to enhance security culture and incident readiness. Overall, the site is secure for users but could benefit from additional security best practices to mitigate emerging threats and demonstrate compliance rigor.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a clear security policy and provide incident response contact information on the website.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website is built on Solidpixels CMS and utilizes modern JavaScript libraries such as Modernizr and Swiper.js for enhanced user experience. Google Tag Manager and Cookie Script are used for analytics and cookie consent management, respectively. The site is mobile-optimized with responsive images and a clear navigation structure. Performance is moderate with room for optimization in loading speed. SEO is well addressed with proper meta tags and Open Graph data. Accessibility is basic but could be improved. The technical infrastructure supports a professional and scalable online presence suitable for a large enterprise in the insurance sector.
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.
