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

Reactflow is a technology company specializing in conversion optimization tools such as session recordings, heatmaps, funnel analytics, bug tracking, and feedback collection. Their platform targets marketers, UX designers, developers, and product managers aiming to improve website performance and customer experience. The company has been operational since 2016 and positions itself as a competitive alternative to established players like Hotjar, emphasizing privacy and GDPR compliance. Technically, the website employs a modern tech stack including Bootstrap, jQuery, and various analytics and tracking tools, hosted behind Cloudflare for performance and security. Security posture is strong with HTTPS enforced, data masking, and containerized services, though some improvements like enabling DNSSEC and adding security headers are recommended. Privacy compliance is good with a clear privacy policy, but lacks an explicit cookie consent mechanism. Overall, the website is professional, trustworthy, and well-structured, with extensive user tracking balanced by stated privacy measures.

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 operates a SaaS business model focused on website analytics and optimization. Their key services include session replay, heatmaps, funnel analytics, bug tracking, and feedback tools. The company targets a diverse audience of digital professionals and emphasizes privacy and compliance as competitive advantages. Customer testimonials from various industries indicate a growing user base and positive market reception. The use of multiple third-party analytics and tracking services suggests a mature marketing and data collection strategy. Partnerships with clients like WebMedic and Flexiroam indicate a broad industry reach. The company maintains a consistent brand and content quality, supporting its credibility and growth potential.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, clientTransferProhibited domain status, and data masking technologies to protect user data. Data transmission uses AES256-CBC cryptography, and services are containerized for isolation. However, the absence of DNSSEC and security headers like Content-Security-Policy and X-Frame-Options represents areas for improvement. No explicit incident response or security policy pages were found, which could impact transparency and readiness. The extensive use of third-party scripts requires ongoing vigilance to prevent vulnerabilities. Overall, the security measures are robust but could be enhanced with additional best practices and transparency.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish a comprehensive security policy and incident response contact information.
  3. Add a cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  4. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  5. Regularly audit and update third-party scripts to minimize vulnerability exposure.

Key observations

  1. Website is fully accessible with rich content and no blocking detected.
  2. Strong focus on privacy and GDPR compliance is stated.
  3. Multiple customer testimonials enhance trust.
  4. Use of multiple third-party analytics and tracking scripts indicates extensive user behavior tracking.
  5. No explicit cookie consent mechanism detected, which may be a compliance gap.
  6. No explicit security or incident response policy pages found.
  7. Domain and hosting setup is professional and consistent with business claims.
  8. Some external domains (cdnhst.xyz, cdnflow.co) used for tracking or scripts may warrant further review.
Technical notes

Notes

The website uses a modern and diverse technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and various plugins for UI enhancements and analytics. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. Performance is optimized with asynchronous script loading and CDN distribution. Accessibility is basic but present, with room for improvement. SEO is supported by proper meta tags and Open Graph data. The site is mobile optimized and visually consistent. Technical debt appears low, but the presence of some less common external domains for tracking scripts suggests a need for ongoing security review.
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.
