Onestein B.V. is a Dutch company specializing in open-source business software solutions, prominently featuring their CURQ ERP system based on Odoo Community. They provide consultancy, support, and custom development services tailored to businesses ranging from startups to enterprises, with a strong emphasis on Dutch financial compliance and community management. The website is professionally designed, well-structured, and optimized for mobile devices, reflecting a mature digital presence. Technically, the site runs on Odoo CMS, uses Matomo for analytics, and employs modern web technologies such as Bootstrap and FontAwesome.

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

8 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 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 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 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

Onestein occupies a niche market as a specialist in open-source ERP solutions with a unique product offering (CURQ) that differentiates it from competitors by focusing on freedom from vendor lock-in and Dutch market needs. Their business model revolves around software implementation, consultancy, and support services, targeting SMEs and larger organizations seeking customizable open-source solutions. The company demonstrates strategic partnerships through integrations with tools like Sendcloud and Matomo, and maintains a presence in the open-source community via GitHub. The SBB-keurmerk certification and client references enhance credibility. Growth potential lies in expanding custom implementations and integrations for diverse industries.

Security posture

The website exhibits a moderate to strong security posture with HTTPS and DNSSEC enabled, CSRF tokens implemented, and use of privacy-conscious analytics (Matomo). However, the lack of visible security headers such as Content-Security-Policy and absence of a cookie consent mechanism reduce compliance with GDPR and modern security best practices. No incident response or security policy information is publicly available, which may impact transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is adequate but could be enhanced by adopting additional headers, explicit privacy controls, and publishing security policies.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and improve privacy transparency.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  3. Publish a clear security policy and incident response contact information to enhance trust and preparedness.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Consider adding a dedicated privacy policy page with detailed GDPR compliance information and data retention policies.

Technical notes

Notes

The website is built on the Odoo CMS platform, leveraging modern frontend technologies such as Bootstrap and FontAwesome for responsive design and UI elements. It uses Matomo analytics for user tracking, indicating a preference for privacy-friendly tools. The site loads asynchronously and defers scripts to optimize performance, achieving moderate loading speeds. Mobile optimization is good, with viewport meta tags and responsive navigation. However, accessibility features are basic and could be improved. The domain uses DNSSEC and HTTPS with a valid SSL certificate, enhancing security. Hosting details are not explicit but domain registrar is Registrar.eu. Overall, the technical infrastructure is solid with opportunities for modernization in accessibility and security headers.
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.
