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

PSG is a well-established construction group in the Czech Republic with nearly a century of tradition. The company operates as a major general contractor and supplier of prefabricated and monolithic construction components, serving industrial, civil, and residential sectors. Their market position is strong, supported by multiple subsidiaries specializing in construction, reinforced concrete, building design, and technical building equipment. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive content including career opportunities and recent projects. Technically, the site employs modern tracking and marketing technologies such as Google Tag Manager, Facebook Pixel, and Leady scripts, alongside the Nette Framework. The site is mobile-optimized and performs moderately well, with good SEO and accessibility features. Security posture is solid with HTTPS enforced and cookie consent implemented, though some security headers could be improved. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain trust signals, but the professional and consistent website content, certifications, and social media presence support legitimacy. Privacy compliance is well addressed with accessible policies and consent mechanisms. Overall, PSG demonstrates a strong business and digital maturity with room for security enhancements and transparency improvements. Strategic recommendations include enhancing security headers, publishing a formal security policy and incident response contacts, and adding a security.txt file to facilitate vulnerability disclosures.

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

9 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      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

PSG holds a significant market position in the Czech construction industry, leveraging a diversified business model that includes general contracting, prefabricated concrete production, building design, and technical building equipment. Their competitive advantage lies in their nearly 100-year history, comprehensive service offerings, and certifications such as LEED and BREEAM. The company targets investors, developers, architects, and industrial clients, focusing on large-scale and complex projects. Revenue streams likely include construction contracts, concrete sales, and technical services. The partnership ecosystem includes subsidiaries like PSG Beton and Autoservis PSG, enhancing service breadth. Growth indicators include recent high-profile projects and active recruitment. The company maintains a strong brand presence with consistent messaging and employee testimonials, supporting trust and credibility.

Security posture

PSG's security maturity is moderate to good. The website enforces HTTPS and implements cookie consent mechanisms aligned with GDPR. Tracking technologies are used responsibly with user consent. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No security.txt or incident response information is published, which could hinder vulnerability reporting and incident management. There are no visible vulnerabilities or exposed sensitive data. Compliance with privacy regulations appears adequate, but formal security policies and incident response contacts would strengthen the security culture and readiness. Overall, PSG shows awareness of security best practices but should enhance transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve communication with security researchers.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities and ensure compliance with privacy regulations.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly, fostering a strong security culture.

Technical notes

Notes

The website is built using the Nette Framework, a modern PHP framework, and integrates multiple third-party analytics and marketing tools such as Google Tag Manager, Google Analytics, Facebook Pixel, and Leady scripts. The site uses responsive design techniques and lazy loading for images, contributing to good mobile optimization and performance. SEO is supported by well-structured meta tags and Open Graph data. The absence of a detected CMS suggests a custom or framework-based solution. Hosting details are not explicit, but HTTPS is enforced indicating a secure hosting environment. Performance is moderate with potential for optimization in loading speed and security header implementation. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
