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

Datlab s.r.o. operates the Tenderman platform, a Czech Republic-focused SaaS tool designed to assist public sector entities and contracting authorities in managing suppliers and tender documentation. The company leverages its expertise in economic data and public procurement to provide a specialized service with a clear market niche and reputable client base including government institutions. The website is professionally designed, mobile-optimized, and uses modern web technologies including Vue.js and Bootstrap, supported by multiple analytics and marketing tools. Security posture is solid with HTTPS and CSRF protections, though lacks published security policies and headers. Privacy compliance is partial, with no explicit privacy or cookie policies found despite cookie consent mechanisms.

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. 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

  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
    • 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

Datlab's market positioning is strong within the Czech public procurement sector, offering a SaaS platform that streamlines supplier discovery and tender management. Their competitive advantage lies in combining technological and economic expertise, supported by a sister nonprofit for public-benefit projects. Revenue likely derives from subscription or licensing fees for access to their database and tools. The target customers are public sector procurement professionals and contracting authorities. The company maintains partnerships with related Datlab services and has a clear brand identity. Growth potential exists through expanding product offerings and deepening market penetration in government procurement.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and CSRF tokens implemented in forms. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party tracking scripts requires ongoing monitoring to mitigate privacy risks. GDPR compliance is partial due to missing privacy and cookie policies. Incident response readiness and vulnerability disclosure mechanisms are not publicly documented, which could impact trust and compliance.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and configure security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Add a dedicated security policy and incident response contact information to demonstrate security maturity and readiness.
  4. Regularly audit and update third-party scripts to minimize vulnerabilities and privacy risks.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern technology stack including Vue.js for frontend interactivity and Bootstrap for responsive design. It integrates multiple analytics and marketing tools such as Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, and Plausible Analytics. Hosting and domain registration are managed by WEDOS, a reputable Czech provider. Performance is moderate with no major issues detected. The site is mobile-optimized and has clear navigation. However, SEO and accessibility could be improved with additional meta tags and ARIA attributes. The presence of CSRF tokens in forms indicates attention to security in data handling.
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.
