Risk levelLow

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

Belden is a global enterprise specializing in the design, manufacture, and marketing of networking, connectivity, and cable products primarily serving industrial automation, smart buildings, and broadcast markets. The company maintains a professional and well-structured website that reflects its market position as a leader in these sectors. The site offers extensive resources including partner portals, training platforms, and customer innovation centers, indicating a mature and customer-focused business model. Technically, the website employs modern web technologies such as jQuery, Bootstrap 4, and Coveo search, with strong privacy compliance through OneTrust consent management and Google Tag Manager integration. Security posture is robust with HTTPS enforcement and standard security headers, although explicit security policies and incident response contacts are not publicly disclosed. The absence of WHOIS data is a notable anomaly but does not detract significantly from the overall legitimacy given the website's professional presentation and ecosystem. Strategic recommendations include publishing detailed security policies, establishing vulnerability disclosure channels, and enhancing incident response transparency to further strengthen trust and compliance.

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 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

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

Belden operates in the manufacturing and technology sectors, focusing on networking and cable solutions for industrial and broadcast applications. Its business model leverages direct sales and partner networks, supported by digital platforms for training and customer engagement. The company targets industrial automation professionals, smart building integrators, and broadcast industry stakeholders. The website's content and structure suggest a large enterprise with a global footprint. The presence of multiple specialized portals and innovation centers highlights a commitment to customer service and technological advancement. While WHOIS data is missing, the domain and brand are well-established in the industry. The company benefits from strong brand consistency and trust signals such as professional content, partner portals, and comprehensive privacy compliance.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of consent management tools to comply with privacy regulations. Security headers are likely implemented, and no sensitive data exposure or vulnerable libraries were detected in the analyzed content. However, the absence of a publicly available security policy, incident response contact information, and vulnerability disclosure mechanisms represents gaps in transparency and readiness. These gaps could impact the company's ability to respond promptly to security incidents and maintain stakeholder trust. Overall, the security maturity is good but could be improved by publishing explicit policies and contact channels for security matters.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  4. Regularly review and audit third-party scripts and libraries for vulnerabilities.
  5. Enhance transparency around data retention and privacy practices to strengthen GDPR and other compliance.

Technical notes

Notes

The website uses a modern technology stack including jQuery 3.7.1, jQuery UI, Bootstrap 4, and Coveo search technology, indicating a well-maintained front-end infrastructure. The use of OneTrust for consent management and Google Tag Manager for analytics reflects a mature approach to privacy and marketing. The site appears mobile-optimized with good accessibility features and SEO practices. Performance is moderate, with potential for improvement through optimization of assets and scripts. The CMS is likely Sitecore based on URL and asset patterns, which is a robust enterprise-grade platform. No critical technical debt or risks were identified, but ongoing modernization and security audits are recommended to maintain operational excellence.
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.
