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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The company operates in the finance sector, focusing on private market data aggregation and analytics. Its business model is subscription-based SaaS, serving niche professional segments such as private equity firms, banks, and M&A teams. The platform consolidates multiple public data sources into a single interface, reducing research time and improving decision quality. Customer testimonials and case studies indicate strong market acceptance and trust. The company leverages partnerships with data providers and uses advanced analytics tools to maintain data quality and relevance. Growth indicators include a large dataset coverage and active client base in Belgium. The company maintains a consistent brand and messaging strategy, reinforcing its market position as a reliable data provider.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, domain transfer lock, and integration of anti-bot measures like Google reCAPTCHA. Consent management is handled via Didomi, supporting GDPR compliance. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests potential areas for enhancement. No incident response or security policy pages were found, indicating a gap in transparency for security governance. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security posture is good but could be improved by adopting additional best practices and publishing formal security documentation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  5. Enhance transparency by providing contact details for security incidents and data protection officer information.

Technical notes

Notes

The website is built on the Webflow CMS platform, leveraging modern JavaScript libraries such as jQuery and Day.js for UI and date handling. It integrates Google Tag Manager and Microsoft Clarity for analytics and user behavior tracking, alongside Didomi for consent management. Hosting appears to be on AWS infrastructure with DNS managed by AWS Route 53. The site is well-optimized for performance and mobile responsiveness, with clean HTML and CSS. The use of reCAPTCHA on forms enhances bot protection. There is no evidence of technical debt or deprecated technologies. Opportunities exist to improve security headers and formalize security and privacy documentation to align with best practices.
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.
