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

CESK, s.r.o. is a Czech company specializing in the sale and servicing of professional gastronomic equipment, including ice cream machines, coffee machines, dispensing technology, and kitchen appliances. With over 30 years of market presence, CESK serves a broad audience ranging from confectioneries, cafes, and restaurants to home users. The company operates an e-shop, offers professional servicing, and organizes training courses, positioning itself as a trusted partner in the hospitality retail sector. The website reflects a mature digital presence with comprehensive product offerings and partner collaborations with reputable brands such as Plzeňský Prazdroj and Heineken. Technically, the website employs modern web technologies including Google Tag Manager, SmartEmailing, and Foxentry for marketing and user interaction. The site is mobile-optimized with good SEO practices and uses HTTPS with secure form handling. However, some security headers are missing, and there is no explicit security policy or incident response information published. From a security and compliance perspective, the site demonstrates good GDPR compliance with a detailed privacy policy and cookie consent mechanism. Contact information is clearly provided, enhancing business credibility. The absence of WHOIS data due to privacy protection slightly reduces trust but is common for commercial entities. No critical vulnerabilities or suspicious activities were detected. Overall, CESK's website is professional, secure, and compliant, supporting its business operations effectively. Strategic improvements in security headers and incident response transparency could further enhance trust and resilience.

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

10 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

    • High

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

CESK holds a solid position in the Czech hospitality equipment market, leveraging long-term partnerships with major beverage and equipment brands. Its business model combines direct sales, servicing, and educational offerings, creating multiple revenue streams and customer touchpoints. The company targets professional gastronomic businesses and home users, indicating a diversified customer base. The presence of a comprehensive e-shop and active marketing tools suggests a digitally mature approach. The partnership ecosystem includes industry leaders, enhancing brand credibility and market reach. Growth indicators include continuous product updates and active event participation. Strategic observations highlight the importance of maintaining strong compliance and security posture to protect customer trust and business continuity.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure form validation, and cookie consent aligned with GDPR. The detailed privacy policy reflects strong data protection awareness. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure mechanisms are publicly available, which could hinder rapid mitigation of security issues. The use of multiple third-party scripts necessitates ongoing security audits to prevent supply chain risks. Overall, the security maturity is good but can be enhanced by formalizing security policies and improving technical controls.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Establish a vulnerability disclosure program, ideally with a security.txt file, to facilitate responsible reporting.
  4. Regularly audit and update third-party scripts and dependencies to minimize vulnerabilities.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, and JavaScript, integrating multiple marketing and analytics tools such as Google Tag Manager, Bing Ads, and SmartEmailing. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate, with potential for improvement by optimizing script loading and reducing third-party dependencies. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site employs asynchronous script loading and deferred execution to improve load times. Technical risks include reliance on multiple external scripts and missing security headers, which should be addressed to reduce attack surface.
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.
