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

The website www.b2bpoptavka.cz operates as a B2B marketplace platform specializing in connecting businesses with tenders and public contracts primarily in the Czech Republic. Managed by ALSENTA s.r.o., the platform has a strong market presence with over 540,000 inquiries and a broad category coverage. The business model focuses on facilitating procurement and supplier matching, targeting companies seeking new customers and contract opportunities. The site is professionally designed with clear navigation and a responsive layout, supporting a positive user experience for its target audience. Technically, the website leverages modern frontend technologies including Bootstrap, jQuery, and Google services such as Analytics and Adsense. The infrastructure supports moderate performance and good mobile optimization. However, no CMS or hosting provider details were identified. The site implements cookie consent mechanisms aligned with GDPR requirements, enhancing privacy compliance. From a security perspective, the site enforces HTTPS and uses consent banners for cookies, but lacks explicit security headers and publicly available security or incident response policies. No vulnerabilities or exposed sensitive data were detected in the content. The absence of WHOIS data due to privacy protection limits domain trust verification, though the website content and business information appear legitimate and professional. Overall, the website presents a solid business platform with good technical and privacy compliance maturity. Strategic improvements in security headers, incident response transparency, and WHOIS data availability would enhance trust and security posture.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

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.

Business context

Business profile

ALSENTA s.r.o. operates www.b2bpoptavka.cz as a specialized B2B tender and public contract portal serving the Czech market and potentially international clients. The company benefits from a long operational history since 1999, positioning itself as a trusted intermediary in procurement processes. Revenue streams likely include subscription or listing fees for tenders and advertising. The platform's extensive category and regional filters indicate a comprehensive service offering. The partnership with its parent company ALSENTA s.r.o. suggests a stable organizational structure. The business targets SMEs and larger enterprises seeking contract opportunities, leveraging digital marketing and Google advertising tools to attract users. Growth indicators include a large user base and frequent tender postings. The ecosystem includes related domains and Google services integration, supporting operational efficiency and market reach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent mechanisms in place, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces the overall security robustness. No public incident response or security policies were found, indicating a gap in transparency and preparedness. The use of multiple third-party scripts (Google Analytics, Adsense) introduces potential risk vectors that require regular auditing. No vulnerabilities or sensitive data exposures were detected in the HTML content. The lack of WHOIS transparency due to privacy protection limits domain trust verification. Overall, the security posture is adequate for the business type but would benefit from enhanced header implementation, documented policies, and continuous security monitoring.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  2. Publish clear security and incident response policies on the website to improve transparency and user trust.
  3. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider disclosing WHOIS registrant information or using a verified domain registration to improve domain trustworthiness.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design, jQuery for DOM manipulation, and Owl Carousel for sliders. Google Fonts enhance typography, while Google Analytics and Tag Manager provide analytics capabilities. The site loads asynchronously Google Ads scripts for monetization. Performance is moderate with some optimization potential. The site is mobile optimized and includes accessibility basics but could improve ARIA roles and keyboard navigation. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site uses a cookie consent banner with granular user controls, indicating good privacy awareness. Overall, the technical implementation supports business needs but could benefit from performance tuning and enhanced accessibility.
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.
