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

Synergrid is the official representative body for Belgian electricity and gas network operators, serving as the primary contact point for sector stakeholders and authorities at both Belgian and European levels. The organization represents nine companies distributing gas and electricity across Belgium, supporting the energy transition and climate goals through innovative projects and sector coordination. The website is professionally designed, multilingual, and provides comprehensive information about the organization, its members, news, and sector-related documentation. Technically, the site is built on Joomla CMS, uses modern JavaScript libraries, and integrates Matomo analytics and Google reCAPTCHA for security and user tracking. Security posture is strong with HTTPS enforced and GDPR-compliant cookie consent mechanisms, although some security headers could be improved. The WHOIS data is restricted, but the website's content and external links to known sector partners indicate high legitimacy. Overall, the site is a reliable and authoritative source for Belgian energy network information.

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

4 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Synergrid holds a key position as a sectoral representative organization in the Belgian energy market, coordinating among major network operators. Its business model focuses on advocacy, standardization, and information dissemination rather than direct commercial activities. The presence of multiple member companies linked on the site indicates a strong partnership ecosystem. The organization targets energy sector stakeholders, regulators, and the general public interested in energy infrastructure and policy. The website's content and structure support transparency and engagement, including newsletters and event information. Growth indicators include active news updates and sector initiatives. The lack of direct commercial transactions suggests a non-profit or governmental affiliated entity.

Security posture

The website demonstrates a mature security posture with HTTPS encryption, use of Google reCAPTCHA v3 on forms to prevent abuse, and a GDPR-compliant cookie consent banner with opt-in mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy or X-Frame-Options is a minor gap. There is no visible incident response or vulnerability disclosure information, which could be improved to enhance transparency and readiness. Overall, the site is secure for visitors and data collection is privacy-aware, but could benefit from additional security best practices and published policies.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish an incident response and vulnerability disclosure policy or security.txt file to improve transparency and facilitate responsible reporting.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built on Joomla CMS with a modern front-end stack including jQuery and custom scripts by Loft33. It integrates Matomo for analytics and Google reCAPTCHA v3 for bot protection. The site is multilingual with proper hreflang tags and uses structured data (JSON-LD) for organization information. Performance is moderate with asynchronous script loading and preconnect hints for Google Fonts. Mobile optimization is good with viewport meta tags and responsive design elements. SEO is supported by meta descriptions, alternate language links, and semantic HTML. Technical risks are low but could be further reduced by adding security headers and improving accessibility compliance.
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.
