zvvz.cz Security Report Summary

zvvz.cz received a security score of 61 out of 100 in Guard's comprehensive security analysis, classified as "Moderate Risk". This report covers ZVVZ GROUP, a.s.'s website security posture. ZVVZ GROUP, a.s. operates in the Energy industry in Czech Republic.

ZVVZ GROUP, a.s. is a leading Czech industrial company specializing in the development, manufacturing, delivery, installation, and servicing of equipment primarily for environmental protection, including flue gas cleaning, filtration, ventilation, nuclear energy, HVAC, and pneumatic transport. The company has a long history dating back to 1948 and operates a group of subsidiaries and partner companies, positioning itself as a major player in the energy and manufacturing sectors. The website reflects a professional B2B business model targeting industrial clients and investors. Technically, the website employs modern web technologies such as Bootstrap, jQuery, Google Tag Manager, and Facebook Pixel, and is built on the VOX.AREA CMS platform. It is mobile optimized with good SEO and accessibility basics, though some improvements in accessibility and security headers could be made. The site uses HTTPS with a strong SSL configuration and implements cookie consent mechanisms, demonstrating compliance with GDPR and related privacy regulations. From a security perspective, the site shows good practices including HTTPS enforcement, privacy policies, and ISO 27001 certification. However, the absence of explicit security headers and public vulnerability disclosure policies indicates room for improvement. No critical vulnerabilities or exposed sensitive data were detected. The lack of WHOIS data reduces transparency and trust slightly but does not negate the legitimacy indicated by the website content and business presence. Overall, the website is professional, secure, and compliant with privacy standards, serving its industrial audience effectively. Strategic recommendations include enhancing security headers, publishing vulnerability disclosure and incident response contacts, and improving accessibility features to further strengthen the security posture and user trust.

The security scan identified 31 findings across security headers, SSL/TLS, DNS health, email security, GDPR compliance, and NIS2 compliance analysis modules.

Technologies detected: jQuery, Bootstrap, Font Awesome, Google Tag Manager, Google Analytics, Facebook Pixel, Revolution Slider, cookieconsent.js.

Security Posture Analysis

Comprehensive Security Assessment

The security posture of the ZVVZ GROUP website is mature, with HTTPS enforced site-wide and implementation of privacy and cookie policies aligned with GDPR. The presence of ISO 27001 certification indicates a formalized information security management system. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests potential areas for hardening against common web attacks. No public vulnerability disclosure or incident response contacts are provided, which could limit transparency and responsiveness in case of security incidents. The use of third-party analytics and tracking tools is balanced with privacy compliance measures. Overall, the site demonstrates good security hygiene but would benefit from enhanced header policies and public security communication.

Strategic Recommendations

Priority Actions for Security Improvement

1

Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
