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

BAU-STAV a.s. is a well-established construction company based in the Karlovy Vary region of the Czech Republic, with nearly 30 years of experience. The company offers a comprehensive range of construction-related services including project design, construction work, steel constructions, locksmith work, transport, and roofing. It primarily serves clients in the Karlovy Vary and Central Bohemia regions but is capable of undertaking projects throughout the Czech Republic. The company is part of the SUAS GROUP, which is disclosed transparently on the website. Technically, the website uses a custom CMS built on the Gambik framework and incorporates modern JavaScript libraries such as jQuery, Bootstrap, and Fancybox. The site is mobile-optimized with good navigation and SEO practices. However, a visible server-side PHP fatal error indicates some backend instability and potential information leakage, which poses a security risk. The site uses HTTPS and Google Analytics with consent settings that deny ad and analytics storage by default, showing some privacy awareness. From a security perspective, the site lacks explicit security headers and formal privacy or cookie policies, which are important for GDPR compliance and user trust. The absence of WHOIS data reduces domain registration transparency and trustworthiness. No incident response or vulnerability disclosure information is provided, limiting the company's security posture visibility. Overall, BAU-STAV a.s. presents a credible and professional business front with room for improvement in backend stability, security best practices, and privacy compliance to enhance trust and reduce risk.

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

  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

BAU-STAV a.s. holds a strong market position as a significant regional construction company with a diversified service portfolio. Its business model focuses on delivering end-to-end construction services, targeting investors and clients in the Czech Republic's real estate sector. The company benefits from its nearly three decades of experience and association with the SUAS GROUP parent company, which may provide financial and operational support. The website highlights a broad project portfolio and company structure, indicating organizational maturity. However, the lack of visible contact details and limited social media presence may constrain direct customer engagement. The partnership with notification system providers and use of Google Analytics suggest some digital marketing efforts. Growth opportunities exist in expanding digital presence and enhancing compliance and security frameworks.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and basic privacy consent settings for analytics. However, the presence of a visible PHP fatal error exposing internal file paths and code details is a critical vulnerability that could aid attackers in reconnaissance. The absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No formal security policies, incident response contacts, or vulnerability disclosure programs are evident, limiting transparency and preparedness. The lack of WHOIS data further reduces trust in domain legitimacy. To improve, the company should address backend errors, implement comprehensive security headers, publish privacy and security policies, and establish incident response mechanisms.

Recommendations

  1. Resolve all server-side PHP errors immediately to prevent information leakage and improve site stability.
  2. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Publish clear and comprehensive privacy and cookie policies with explicit GDPR compliance and consent mechanisms.
  4. Establish and publicize an incident response contact and vulnerability disclosure program to enhance security transparency.
  5. Obtain and maintain accurate WHOIS domain registration information to improve domain legitimacy and trust.

Technical notes

Notes

The website is built on a custom CMS using the Gambik framework version 5.030, leveraging popular JavaScript libraries such as jQuery, Bootstrap, Fancybox, and Moment.js. The front-end is responsive and optimized for mobile devices with good SEO meta tags and Open Graph data. However, the backend shows a critical PHP error related to a function expecting a countable argument, indicating technical debt or insufficient error handling. The site loads external resources from cdn.pivovarcik.cz and uses Google Analytics and Tag Manager for tracking. No clear hosting provider information is available. Performance is moderate, with potential improvements by fixing backend errors and optimizing resource loading. Accessibility is basic and could be enhanced for compliance and user experience.
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.
