Risk levelLow

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

Twintos B.V. is a specialized Dutch company focused on database consultancy, optimization, and real-time monitoring services. Their website positions them as the leading database experts in the Netherlands, serving critical sectors such as healthcare, public transport, and banking. The company emphasizes the importance of reliable and secure data systems for organizations where information is crucial. Technically, the website is built on modern frameworks like Next.js and React, with good performance and mobile optimization. Security posture is solid with HTTPS enforced, but lacks explicit security headers and published security policies. Privacy compliance is partial, with a cookie consent mechanism but no clear privacy policy or terms of service pages. The absence of WHOIS registration data is a concern for domain legitimacy, though the professional website and detailed case studies suggest a legitimate business. Overall, Twintos demonstrates a mature digital presence with room for improvement in transparency and security disclosures.

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

2 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. 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

Twintos operates in the technology sector with a focus on database services for essential industries including transportation and government. Their business model revolves around providing expert consultancy and technical services to organizations dependent on complex data infrastructures. The company showcases strong market positioning through high-profile case studies and a consistent brand image. Revenue streams likely derive from service contracts and consultancy fees. The target customers are organizations requiring high availability and security of data, such as hospitals and public transport operators. Growth indicators include recent case studies and active marketing via digital channels. The partnership ecosystem includes clients like NS, ProRail, and government entities, though no explicit partner domains were identified. Strategic observations highlight the need for enhanced transparency in privacy and security policies to strengthen trust further.

Security posture

Twintos maintains a good security posture with HTTPS enabled and no visible exposure of sensitive data. However, the website lacks important security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. There is no published security policy or incident response information, and no vulnerability disclosure or security.txt file was found. The cookie consent mechanism indicates some privacy awareness, but the absence of a privacy policy page reduces compliance confidence. No contact emails or phone numbers for security or abuse reporting are provided. Overall, the security maturity is moderate with opportunities to improve transparency, policy publication, and technical security controls.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages linked in the website footer.
  2. Add standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Publish a security policy and incident response page including contact details for security issues.
  4. Provide verified company contact emails and phone numbers on the website for general and security inquiries.
  5. Verify and update WHOIS registration information to ensure domain legitimacy and transparency.

Technical notes

Notes

The website uses a modern tech stack including Next.js and React, ensuring good performance and mobile responsiveness. Font Awesome 6 is used for icons, and Google Tag Manager and Reddit Pixel are integrated for analytics and advertising. The site is well-structured with proper meta tags and Open Graph data for SEO and social sharing. No CMS was detected, suggesting a custom or static site generation approach. Hosting provider details are not evident from the HTML. Performance appears fast with preloading of fonts and images. Accessibility is good with semantic HTML and ARIA attributes. Technical risks include missing security headers and incomplete privacy disclosures, which could impact compliance and security posture.
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.
