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

Trustoo is a well-established Dutch online platform founded in 2018 that specializes in connecting consumers and businesses with local service providers across a wide range of categories including legal, home improvement, personal services, and events. The platform positions itself as the leading service comparison site in the Netherlands, offering users the ability to compare companies based on reviews and pricing, facilitating informed decision-making. Trustoo operates subsidiaries in Belgium, Germany, and Spain, indicating a regional expansion strategy. Technically, the website is built on modern web technologies such as Next.js and React, ensuring fast performance and excellent mobile optimization. The use of Cookiebot for cookie consent and integration with Google Tag Manager and Bing Ads reflects a mature digital marketing and privacy compliance approach. The platform leverages structured data (JSON-LD) for SEO and maintains a professional, user-friendly design with clear navigation. From a security perspective, the site uses HTTPS and employs cookie consent mechanisms, but lacks DNSSEC and explicit security headers, which are recommended for enhanced protection. No direct contact emails or phone numbers are publicly listed, and no formal privacy policy or terms of service were found in the provided content, which could be improved to strengthen compliance and user trust. Overall, Trustoo presents a high-quality, trustworthy service platform with strong market presence in the Netherlands. Strategic improvements in security policies and transparency would further enhance its credibility and compliance posture.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

Trustoo operates as a digital marketplace and comparison platform targeting the Dutch market primarily, with subsidiaries in neighboring countries. Its competitive advantage lies in aggregating extensive local service provider data, user reviews, and pricing information, enabling consumers to make quick and informed choices. The business model is based on facilitating connections between customers and service providers, likely monetized through lead generation or advertising. The platform's extensive service categories and integration with review platforms like Trustpilot support its market leadership claim. The presence of multiple social media channels and a modern tech stack indicates a focus on digital growth and customer engagement.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and cookie consent management via Cookiebot, supporting GDPR compliance. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents potential areas of vulnerability. No incident response or security policy information is publicly available, which limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The platform would benefit from publishing a vulnerability disclosure policy and enhancing domain security features.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement and configure security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  3. Publish a clear privacy policy and terms of service pages accessible from the homepage to improve compliance and user trust.
  4. Provide explicit contact information for security incidents, including a security@ or abuse@ email address.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built using Next.js and React frameworks, indicating a modern, server-side rendered React application optimized for performance and SEO. The use of Cookiebot for cookie management and Google Tag Manager for analytics shows adherence to privacy and marketing best practices. The site loads quickly and is well-optimized for mobile devices, with responsive design and accessibility considerations. Hosting details are limited but the registrar is a reputable Dutch provider. No CMS was explicitly detected, suggesting a custom or headless CMS solution. The technical implementation is robust with room for security enhancements.
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.
