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

California Eastern Laboratories (CEL) is a specialized technology company providing wireless connectivity solutions including WiFi, Bluetooth, and Zigbee modules primarily for IoT developers and OEMs. With a legacy of over 60 years in RF technology, CEL positions itself as a trusted partner delivering high-performance RF components and integration support to accelerate market entry and competitiveness. The website reflects a professional and focused business presence with clear product categories and market sectors served. Technically, the website is built using modern web technologies including Hugo CMS, Bootstrap, jQuery, and integrates Google Analytics and HubSpot for marketing and analytics. The site is mobile optimized, uses HTTPS with strong SSL configuration, and includes a GDPR-compliant cookie consent mechanism. However, some areas such as accessibility and security headers could be improved. From a security perspective, the site demonstrates good practices with HTTPS, cookie consent, and no visible vulnerabilities or exposed sensitive data. The absence of a published security policy, incident response contacts, and terms of service pages are gaps that could be addressed to enhance trust and compliance. The WHOIS data is unavailable, which reduces domain trust verification, but the professional site content and branding mitigate some concerns. Overall, CEL's website is a solid representation of a mid-sized technology company with good digital maturity and security posture, though improvements in transparency and domain registration clarity are recommended to 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

4 findings rated critical or high. Fix these first.

  1. 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

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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

CEL operates in the wireless technology sector, targeting OEMs and IoT developers with specialized RF components and wireless modules. Their competitive advantage lies in their 60+ years of RF expertise and comprehensive support services. The business model is B2B focused, providing hardware components and integration assistance. The company serves diverse markets including building controls, lighting, smart energy, industrial, smart home, medical, HVAC, and security. The website indicates a medium-sized enterprise with a strong brand and consistent messaging. The partnership ecosystem is not explicitly detailed, and no related or subsidiary domains were identified. Revenue streams likely come from product sales and technical support services. Growth indicators include a modern website and active marketing tools.

Security posture

The website exhibits a mature security posture with enforced HTTPS, cookie consent with granular controls, and no visible security vulnerabilities or exposed sensitive data. However, the lack of published security policies, incident response contacts, and terms of service pages represent compliance and transparency gaps. No security headers were detected in the provided data, suggesting room for improvement. The WHOIS data absence is a concern for domain legitimacy verification. Overall, the security maturity is good but could be enhanced by formalizing policies and improving header configurations. GDPR compliance is indicated through privacy and cookie policies.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Add explicit incident response contact information such as security@ or abuse@ email addresses.
  3. Create and publish a terms of service page to clarify user agreements and liabilities.
  4. Implement additional security headers like Content-Security-Policy and X-Frame-Options to harden site security.
  5. Improve accessibility features to meet WCAG standards for broader user inclusivity.

Technical notes

Notes

The website is built on the Hugo static site generator, leveraging Bootstrap for responsive design and jQuery for interactivity. It uses modern libraries such as Ionicons for icons, Magnific Popup for modals, Slick for carousels, and Shuffle.js for filtering. Google Analytics (GA4) and HubSpot are integrated for analytics and marketing automation. The site loads scripts deferred for performance optimization and uses preconnect and preload hints for resource loading efficiency. Mobile optimization is good, but accessibility is basic and could be improved. No CMS backend detected beyond Hugo static generation. Hosting provider details are not available from the data. Overall, the technical stack is modern and well implemented with moderate performance.
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.
