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

SUDOP GROUP a.s. is a large, well-established company based in the Czech Republic specializing in design, consulting, and IT services primarily for the construction, transportation, energy, and water management sectors. The company positions itself as the largest group of such companies in Central Europe, offering services including Construction and BIM, Consulting & IT, and Research & Development. Their business model focuses on digitalizing construction processes and providing engineering preparation for infrastructure projects. The website content is professional and targeted at business clients in relevant industries. Technically, the website employs modern web technologies including Google Tag Manager, Google Analytics, and Google Maps API. It is mobile-optimized with good SEO and accessibility features, though some accessibility improvements could be made. Performance is moderate with efficient use of scripts and stylesheets. The site uses HTTPS with an excellent SSL configuration but lacks explicit security headers such as CSP or HSTS. From a security perspective, the site demonstrates good practices including HTTPS enforcement and a comprehensive cookie consent mechanism with granular user controls. No exposed sensitive data or vulnerable libraries were detected. However, the absence of WHOIS data and security.txt or incident response contacts slightly reduces trust. There are no visible forms collecting user data on the homepage, reducing attack surface. Overall, the security posture is solid but could be enhanced with additional headers and published incident response policies. The domain WHOIS data is unavailable, which is a concern for trust but may be due to privacy protection or registry issues. The website content and business information appear legitimate and professional, mitigating some concerns. The overall risk is moderate with recommendations to improve transparency and security headers to enhance trust and compliance.

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

8 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 a dedicated cookie policy explaining cookie usage and purposes

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

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

SUDOP GROUP a.s. holds a strong market position as the largest design, consulting, and IT group in Central Europe focused on construction and infrastructure sectors. Their competitive advantage lies in integrating IT expertise with traditional engineering services to push the building sector towards Construction 4.0. The company targets large infrastructure projects in transportation, energy, and water management, serving government and private sector clients. Revenue streams likely include consulting fees, project design contracts, and IT solutions. Growth indicators include active R&D and digitalization initiatives. The company maintains a compliance page and legal registration, indicating a mature governance structure. No explicit partnerships or subsidiaries were identified from the website content.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a detailed cookie consent mechanism supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were found. However, the lack of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap that could be exploited. Incident response and vulnerability disclosure information are not published, which limits transparency and readiness perception. The absence of WHOIS data reduces domain trustworthiness. Overall, the security maturity is good but could be improved by publishing security policies and adding security headers.

Recommendations

  1. Implement and publish a vulnerability disclosure policy or security.txt file to improve transparency and encourage responsible reporting.
  2. Add essential security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  3. Publish incident response contact information or a dedicated security contact email to improve readiness and trust.
  4. Improve accessibility features to meet higher standards, ensuring better usability for all users.
  5. Investigate and resolve the missing WHOIS data issue to enhance domain trust and legitimacy.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager, Google Analytics, Google Maps API, and polyfills for browser compatibility. It employs responsive design and lazy loading for images and videos, contributing to good performance and user experience. The site uses standard HTML5 and CSS with no detected CMS, suggesting a custom-built platform. Hosting provider details are not disclosed. Performance is moderate with room for optimization. Accessibility is basic with some ARIA landmarks and skip links but could be improved. SEO is good with proper meta tags, Open Graph, and structured data in JSON-LD format. No broken links or errors were detected.
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.
