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. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Reactflow positions itself as a competitive alternative to established analytics tools like Hotjar, emphasizing privacy and accuracy. Its business model is subscription-based SaaS, focusing on conversion optimization for digital businesses. The company showcases multiple customer testimonials and brand partnerships, indicating a growing user base and market acceptance. The target audience includes professionals across marketing, UX, development, and product management. The company has been operational since 2016, with a consistent domain registration history. The ecosystem includes partnerships with various companies displayed on the website, enhancing credibility and reach.

Security posture

The security maturity level is moderate to good, with HTTPS enforced and enterprise-grade encryption for data transmission. The website mentions privacy-respecting technologies such as layout matching masking to protect customer data. However, the absence of DNSSEC and lack of explicit security headers reduce the overall security posture. No public incident response or vulnerability disclosure information is available, which could be improved to enhance transparency and trust. The use of third-party tracking pixels (Google Analytics, Facebook Pixel, Hitsteps) indicates extensive user tracking, but privacy compliance is addressed through masking and GDPR focus.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement and publish a security.txt file to facilitate vulnerability reporting.
  3. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Introduce a cookie consent banner to comply fully with privacy regulations.
  5. Provide clear incident response contact information to improve transparency and trust.

Technical notes

Notes

The website uses a modern and diverse technology stack including jQuery, Bootstrap, Chart.js, and various UI enhancement libraries. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site loads quickly and is mobile optimized with responsive design. SEO is supported with proper meta tags and Open Graph data. Accessibility is basic but present. There is no detected CMS, suggesting a custom or static site architecture. The site integrates multiple third-party analytics and marketing tools, which are well implemented but could be better balanced with privacy controls.
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.
