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

5 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 AI personalization and recommendation engine market, serving a broad range of industries with tailored solutions. Its competitive advantage lies in its comprehensive API offerings, real-time analytics, and extensive SDK support. The company leverages partnerships with academic and technology leaders to maintain innovation and credibility. Revenue streams likely include subscription-based SaaS plans and enterprise contracts. The target customers are businesses seeking to improve user engagement and conversion through AI-driven personalization. Growth indicators include a large client base, industry awards, and positive client testimonials. The partnership ecosystem includes reputable academic institutions and technology providers, enhancing Recombee's market position.

Security posture

Recombee exhibits a mature security posture with HTTPS enforcement and anti-bot measures via Google reCAPTCHA. The website does not expose sensitive data and employs secure form validation. However, the absence of explicit security headers like X-Frame-Options and a public incident response or security policy page indicates room for improvement. There is no evidence of a vulnerability disclosure program or security.txt file. GDPR compliance is indicated through a comprehensive privacy policy and cookie consent mechanisms. Incident response readiness and security culture indicators are not publicly documented, suggesting an opportunity to enhance transparency and trust.

Recommendations

  1. Publish explicit security headers such as X-Frame-Options and X-Content-Type-Options to strengthen browser security.
  2. Create and publish a security.txt file and a dedicated incident response page to facilitate vulnerability reporting and improve transparency.
  3. Enhance public documentation of data protection officer contact and incident response procedures to align with best compliance practices.
  4. Regularly audit third-party scripts and tracking tools to ensure minimal privacy impact and maintain GDPR compliance.
  5. Verify and update domain WHOIS registration information to eliminate legitimacy concerns and improve trust signals.

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.
