Recombee is a technology company specializing in AI-powered recommendation and personalized search services delivered as a SaaS platform. Their offerings include real-time personalized recommendations, advanced search capabilities, and analytics tools tailored for diverse industries such as video streaming, e-commerce, media, real estate, and more. The company targets product managers and technical teams seeking to enhance user engagement and conversion rates through AI-driven personalization. With a strong market presence evidenced by partnerships with major brands and numerous client testimonials, Recombee positions itself as a leading provider in the AI recommendation space. Technically, Recombee employs a modern web stack including React and Next.js, with extensive use of RESTful APIs and SDKs for multiple programming languages. The website demonstrates excellent performance, mobile responsiveness, and SEO optimization. Integration of Google Tag Manager, Hotjar, and Usercentrics indicates a mature approach to analytics and privacy compliance. However, explicit security headers are not detected, and no dedicated security policy or incident response page is published. From a security perspective, the site uses HTTPS and implements reCAPTCHA on forms, along with consent management for cookies, reflecting good baseline security and privacy practices. The absence of WHOIS data is likely due to privacy protection, which is justified for this business type. No critical vulnerabilities or suspicious indicators are found in the content or technical setup. Overall, Recombee presents a professional, trustworthy, and technically sound platform with strong business credibility. Strategic recommendations include enhancing security header implementation, publishing a formal security policy, and adding a vulnerability disclosure mechanism to further strengthen trust and compliance.

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

6 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 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 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  3. 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

Recombee operates in the competitive AI personalization market, leveraging advanced machine learning to deliver tailored recommendations and search experiences. Their SaaS model allows scalable deployment across industries, supported by a robust developer ecosystem with SDKs and comprehensive documentation. The company’s client base includes prominent media and e-commerce brands, indicating strong market validation. Partnerships with academic and technology leaders enhance their innovation pipeline. Revenue streams likely include subscription fees and enterprise contracts. The company’s growth is supported by awards and positive client testimonials, reflecting effective market positioning and customer satisfaction. Recombee’s strategic focus on flexibility and configurability caters to diverse use cases, providing a competitive advantage in customization and integration.

Security posture

Recombee demonstrates a solid security posture with mandatory HTTPS, form protections via Google reCAPTCHA, and user consent management through Usercentrics. The site avoids exposing sensitive data and integrates tracking and analytics responsibly. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options represents an area for improvement. No explicit security or incident response policies are published, which could impact transparency and readiness perception. The absence of a security.txt file or vulnerability disclosure channel limits external reporting options. Overall, the security maturity is good but can be enhanced by adopting additional best practices and formalizing security governance documentation.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response page accessible from the website footer.
  3. Create and maintain a security.txt file to facilitate vulnerability disclosures.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.
  5. Enhance transparency by providing data retention policies and detailed privacy compliance documentation.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring fast loading times and excellent mobile responsiveness. The use of RESTful APIs and multiple SDKs supports broad integration capabilities. Analytics and consent management tools are well integrated, supporting privacy compliance. The site structure and metadata are optimized for SEO, with clear navigation and rich content. No CMS is explicitly detected, suggesting a custom or headless architecture. Hosting provider details are not disclosed. Technical risks are minimal, but the absence of some security headers and formal security documentation could pose future compliance challenges. Overall, the technical infrastructure is robust and scalable, supporting Recombee’s business objectives effectively.
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.
