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

Quantyoo GmbH & Co. KG is a specialized data analytics and marketing services provider based in Munich, Germany. Founded in 2019, the company focuses on enabling businesses to leverage data for product development, research, and marketing through advanced tools and AI-driven solutions. Their market position is that of a trusted data specialist serving media and related sectors, with a clear emphasis on data-driven decision-making and customer insights. The website presents a professional, well-structured, and content-rich digital presence that effectively communicates their value proposition and services. Technically, the website is built with modern web technologies including HTML5, CSS3, JavaScript, and Alpine.js, hosted on Amazon AWS infrastructure. The site is fast, mobile-optimized, and accessible, with good SEO practices. Security measures include HTTPS enforcement and CAPTCHA on forms, though some security headers are missing and no explicit incident response or vulnerability disclosure policies are published. The security posture is solid with encrypted data storage claims and password security guidance, but could be improved by adding security headers and formal policies. Privacy compliance is strong with a comprehensive GDPR policy, but lacks a cookie consent mechanism. Business credibility is high, supported by detailed contact information, customer testimonials, and professional branding. Overall, Quantyoo presents a trustworthy and professional online presence with a strong focus on data-driven business solutions. Strategic improvements in security policies and privacy mechanisms would further enhance their trust and compliance standing.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

Quantyoo operates in the media sector, targeting businesses and data professionals seeking to harness data for competitive advantage. Their business model centers on providing plug-and-play data infrastructure, analytics, and AI-powered marketing tools. They emphasize ease of integration, GDPR compliance, and personalized customer engagement. The company leverages partnerships with regional radio networks and media companies, as evidenced by customer testimonials. Growth indicators include a focus on expanding data capabilities and on-demand expertise. Their ecosystem includes proprietary algorithms, visualization tools, and a login system for first-party data, positioning them well in the evolving data privacy landscape.

Security posture

Quantyoo demonstrates a mature security posture with HTTPS enforced site-wide and encrypted data storage. The inclusion of CAPTCHA on contact forms reduces spam and automated abuse risks. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents a gap. No public incident response or vulnerability disclosure policies were found, which could impact transparency and trust. Password security is emphasized in FAQs, indicating a security-aware culture. Overall, the security measures are adequate for the business type but could be enhanced with formal policies and additional technical controls.

Recommendations

  1. Implement and publish a comprehensive security policy including security headers (CSP, X-Frame-Options, etc.) to harden the website against common attacks.
  2. Add a cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Publish an incident response and vulnerability disclosure policy to improve transparency and trust with customers and security researchers.
  4. Include terms of service to clarify user rights and obligations, reducing legal risks.
  5. Regularly review and update security practices and conduct penetration testing to identify and mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern, performant tech stack including Alpine.js for interactivity and Kibana for data visualization. Hosting on AWS DNS infrastructure ensures reliability and scalability. The site is mobile-optimized with responsive design and good accessibility features. SEO is well addressed with meta tags and Open Graph data. No CMS was detected, suggesting a custom or static site approach which reduces some attack surfaces but requires careful maintenance. Performance is fast with preloading and module preloading techniques used. The technical implementation is robust with room for improvement in security headers and privacy mechanisms.
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.
