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

PREOL, a.s. is a leading Czech company specializing in the processing of rapeseed seed and production of related products such as biofuels, animal feed, and food products. It operates as part of the AGROFERT group, a major player in the Czech agricultural and energy sectors. The website presents a professional image with clear branding, multilingual support, and comprehensive information about its business activities and compliance with GDPR regulations. The company targets both general consumers and business partners in the energy and agricultural industries. Technically, the website uses a custom CMS (Poski), JavaScript libraries such as jQuery, and includes responsive design features for mobile optimization. While the site performs moderately well, there is room for improvement in accessibility and security headers. The cookie consent mechanism and GDPR information demonstrate a commitment to privacy compliance. From a security perspective, the site lacks visible security headers and explicit incident response or security policy pages, which could be enhanced to improve trust and resilience. The absence of WHOIS data is a concern for domain legitimacy, although the website content and business information align with a reputable corporate entity. Overall, the site is secure enough for general use but would benefit from strengthened security practices and transparency. The overall risk assessment is moderate with recommendations to improve security headers, SSL configuration, and incident response transparency. These steps will enhance user trust and regulatory compliance, supporting the company’s strong market position in the Czech energy and agricultural sectors.

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

7 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

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

PREOL, a.s. holds a strong market position as the largest Czech processor of rapeseed seed, producing biofuels, feed, and food products. Its affiliation with AGROFERT provides strategic advantages including resource access and brand recognition. The business model focuses on leveraging traditional Czech raw materials to supply multiple sectors, including energy and agriculture. The website’s multilingual support indicates an intent to reach both domestic and international audiences. The company’s clear contact information and GDPR compliance suggest operational maturity. However, the lack of visible certifications or security policies may indicate areas for growth in corporate governance and compliance transparency. The partnership ecosystem is centered around AGROFERT, with no other partners explicitly linked. Growth indicators are not directly visible but the company’s large size and market leadership imply stable operations.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is implied but not explicitly confirmed in the data. The presence of a cookie consent banner and GDPR information indicates awareness of privacy regulations. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response contacts or vulnerability disclosure mechanisms are found, limiting transparency and readiness for security events. The WHOIS data is missing, which can be a red flag for domain legitimacy, although the website content is consistent with a legitimate business. No vulnerable libraries or exposed sensitive data were detected in the HTML content. Overall, the site is functional and compliant at a basic level but should enhance security controls and transparency to reduce risk.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Verify and strengthen SSL/TLS configuration to ensure encrypted communications meet current best practices.
  3. Publish explicit security policies and incident response contact information to improve transparency and user trust.
  4. Conduct regular audits of third-party scripts and libraries to identify and remediate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance with standards and broaden user inclusivity.

Technical notes

Notes

The website is built on a custom CMS platform (Poski) and uses JavaScript libraries such as jQuery and FontAwesome for UI components. The site is mobile responsive and includes SEO-friendly meta tags and Open Graph properties. Performance is moderate with no major issues detected, though no advanced performance optimization techniques are evident. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. The site lacks modern security headers and explicit SSL/TLS configuration details are unavailable. The absence of analytics scripts suggests minimal user tracking, aligning with privacy compliance goals. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security controls.
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.
