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

TenderMarket.cz is a Czech language website focused on providing information and guidance related to tendering and procurement processes, targeting suppliers and contracting authorities. The platform appears to serve as an informational resource rather than a transactional or e-commerce site. The website uses modern web technologies such as Angular and Material Design components, hosted on Czech hosting infrastructure. However, the site lacks visible privacy, cookie, and terms of service policies, which are important for compliance and user trust. Security headers and explicit security policies are not evident, indicating room for improvement in security posture. The domain is well aged and registered with a reputable Czech registrar, supporting the legitimacy of the business. Overall, the site is functional but basic in content and compliance features.

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"

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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The business operates in the procurement and tendering sector, likely serving government or private contracting authorities and suppliers in the Czech Republic. The business model appears to be informational and service-oriented, providing guidance on tender processes. The lack of visible contact details and policies suggests a small to medium-sized operation with limited digital maturity in compliance and security. The domain age and consistent WHOIS data indicate a stable presence. There is no evidence of partnerships or subsidiaries from the provided data. The platform could benefit from enhanced transparency and user engagement features to strengthen market position.

Security posture

The current security posture is minimal. The website uses HTTPS (implied by the URL), but no security headers are detected in the HTML content. There are no visible privacy or cookie policies, nor incident response or vulnerability disclosure mechanisms. No contact channels for security incidents are provided. The absence of security best practices such as CSP, HSTS, or X-Frame-Options reduces the site's resilience against common web threats. No vulnerable libraries or exposed sensitive data were detected in the HTML content. Overall, the security maturity is low, and improvements are recommended to meet compliance and protect user data.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Provide clear contact information including emails and phone numbers for general and security incident reporting.
  4. Establish and publish an incident response policy and vulnerability disclosure program, including a security.txt file.
  5. Enhance SEO, accessibility, and mobile optimization to improve user experience and reach.

Technical notes

Notes

The website is built using Angular 19 framework with Material Design components and uses Google Fonts for typography. Hosting is provided by websupport.cz, a Czech hosting provider. The site loads multiple JavaScript chunks and stylesheets, indicating a modular and modern frontend architecture. Performance is moderate with no explicit indicators of slow loading but no advanced optimization detected. Mobile optimization is basic, with some responsive styles but minimum adaptive design for smaller screens. Accessibility features are minimal, with no ARIA landmarks or enhanced semantic markup detected. SEO optimization is basic, with a simple title tag but no meta description or Open Graph tags found. The technical stack is modern but could benefit from improvements in SEO, accessibility, and security configurations.
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.
