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

Colbe is a European network specializing in workplace health and wellbeing, aiming to help employees feel better and maintain wellbeing at work. The company operates as a network of health and wellbeing specialists, providing integrated services such as corporate wellbeing, employee assistance, and absence management. The website presents a professional and consistent brand image, targeting organizations and employees across Europe, particularly in the Netherlands. The business is positioned as a trusted partner to leading European organizations, emphasizing connection and sustainable wellbeing. Technically, the website is built using modern frameworks including Next.js and React, with Google Tag Manager integrated for analytics. The site is mobile-optimized, accessible, and SEO-friendly, offering a smooth user experience. However, some technical improvements are recommended, such as implementing security headers and publishing a security policy. From a security perspective, the site uses HTTPS with good SSL configuration and no visible vulnerabilities or exposed sensitive data. Privacy compliance is strong, with clear privacy and cookie policies and consent mechanisms in place. However, the absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. Overall, the website is professional and trustworthy in content and design, but the lack of WHOIS data and explicit contact emails or phone numbers slightly reduces business credibility. Strategic recommendations include verifying domain registration, enhancing security headers, and publishing incident response information to improve trust and security 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

3 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"

    • 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

Colbe operates in the healthcare and wellbeing sector, focusing on workplace wellbeing solutions for organizations in Europe. Its business model revolves around a network of specialist providers delivering holistic services to improve employee health and organizational resilience. The company leverages partnerships with prominent European organizations, enhancing its market position and credibility. Revenue streams likely include service contracts with corporate clients.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no detected vulnerabilities or exposed sensitive data. Privacy policies and cookie consent mechanisms align with GDPR requirements, indicating compliance awareness. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies suggest areas for improvement. No security.txt file or dedicated incident response contact channels were found, which could hinder vulnerability reporting and incident management. Overall, the security maturity is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Verify and publish accurate WHOIS domain registration information to improve trust and legitimacy.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Publish a formal security policy and incident response plan accessible on the website.
  4. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  5. Include explicit company contact emails and phone numbers to enhance business credibility and user trust.

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.
