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 as a service provider delivering expert database consultancy and optimization services. Their market positioning is strong within the Netherlands, targeting organizations where data availability and security are critical, including hospitals, public transport, and banks. The business model is service-oriented with a focus on high responsiveness and specialized expertise. The company showcases client success stories and a professional team, indicating a mature operation with growth potential. Partnerships or subsidiaries are not evident from the data. Marketing and advertising utilize Google and Reddit platforms, with moderate user tracking balanced by privacy compliance measures.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, multiple security headers, and a cookie consent mechanism. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy, incident response plan, or vulnerability disclosure reduces transparency. No direct security contact emails were found, which could hinder incident reporting. Compliance with GDPR is indicated by the privacy and cookie policies. Overall, the security maturity is good but could be improved by publishing explicit security governance documents and contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Provide direct security contact emails such as security@twintos.com or abuse@twintos.com.
  4. Regularly review and audit third-party scripts and tracking pixels for security risks.
  5. Enhance accessibility features to improve inclusivity and compliance.

SEO is well implemented with comprehensive meta tags, Open Graph, and JSON-LD structured data.

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.
