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

Lightning Web Components (LWC) is an open source web components framework developed and maintained by Salesforce.com, Inc., a leading enterprise cloud software company. The website serves as the official documentation and resource hub for developers to learn and implement LWC technology. It targets web developers and enterprise software engineers seeking a performant, standards-based framework for building web applications. The site is professionally designed with clear navigation, mobile optimization, and comprehensive content, reflecting Salesforce's strong market position and commitment to developer enablement. Technically, the site leverages modern web technologies including HTML5, CSS3, ES6+ JavaScript, and Web Components standards. It integrates third-party services such as Google Analytics, Google Tag Manager, Algolia DocSearch for search functionality, and OneTrust for cookie consent management, demonstrating a mature digital infrastructure. Hosting appears to be managed by Salesforce, ensuring reliability and performance. Accessibility and SEO best practices are well implemented. From a security perspective, the site enforces HTTPS, employs cookie consent mechanisms, and avoids exposing sensitive data. However, explicit security policies and incident response contacts are not published, representing an area for improvement. No vulnerabilities or suspicious activities were detected. Privacy compliance is strong, with a comprehensive privacy policy linked to Salesforce's main privacy statement and a robust cookie consent manager. Overall, the website is a trustworthy, high-quality resource aligned with Salesforce's enterprise reputation. It effectively supports its developer audience with clear, relevant content and a secure, performant platform. Strategic recommendations include publishing dedicated security and incident response policies, adding vulnerability disclosure information, and enhancing contact information availability 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

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 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';…

  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

Salesforce.com, Inc. operates Lightning Web Components as part of its open source developer ecosystem, positioning itself as a leader in enterprise cloud software and developer tools. The business model focuses on providing high-quality frameworks and documentation to foster adoption and community contributions, indirectly supporting Salesforce's broader platform offerings. The target market includes professional developers and enterprises seeking modern web development solutions. The site reflects Salesforce's competitive advantage in combining open standards with enterprise-grade features. Partnerships with GitHub and use of industry-standard tools indicate a mature ecosystem. Growth indicators include active community engagement and continuous framework updates. The absence of direct sales or contact information suggests the site is primarily informational and community-focused.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, use of cookie consent management via OneTrust, and no visible exposure of sensitive information. Security headers are likely implemented though not explicitly visible in the HTML. The absence of a published security policy or incident response contact limits transparency and readiness communication. No known vulnerabilities or outdated libraries were detected. GDPR compliance is supported through privacy and cookie policies. The site would benefit from publishing a security.txt file or vulnerability disclosure program to enhance security maturity and stakeholder confidence. Overall, the security posture is strong but could be improved with formalized policies and incident response details.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure program or security.txt file.
  4. Enhance contact information availability to improve user trust and support.
  5. Regularly review and update third-party scripts and dependencies to mitigate risks.

Notes

The website is built on a modern, standards-based technology stack including Lightning Web Components, HTML5, CSS3, and ES6+ JavaScript. It integrates third-party services for analytics (Google Analytics, Google Tag Manager), search (Algolia DocSearch), and cookie consent (OneTrust). Hosting is managed by Salesforce, ensuring high availability and performance. The site is mobile-optimized, accessible, and SEO-friendly. No CMS is detected, indicating a custom or static site architecture. Performance is fast with minimal boilerplate code. Technical risks are low, but continuous monitoring of third-party libraries and scripts is recommended to avoid vulnerabilities. Opportunities exist to formalize security and compliance documentation to reduce technical debt and enhance governance.
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.
