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

7 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

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 company targets businesses involved in public procurement, offering subscription-based access to tender data and market insights. Their competitive advantage lies in comprehensive data coverage, expert analysis, and tailored notifications. The business model relies on recurring revenue from subscriptions and consultancy services. The website reflects a mature digital presence with multilingual support and partner networks across several countries. Testimonials and free trial offers enhance credibility. The company is part of the Tender Service Group, indicating a broader organizational structure. Growth potential exists through expanding international tender coverage and enhancing digital services.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, modern security headers, and secure form handling. Cookie consent and privacy policies align with GDPR requirements. However, the absence of a public security policy, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party analytics and tracking scripts is managed with user consent. Overall, the security posture is solid but could benefit from enhanced documentation and proactive disclosure policies.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Regularly review and update third-party scripts to mitigate potential security risks.

Notes

The infrastructure supports a professional and scalable digital presence suitable for the business model.
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.
