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's LWC framework positions itself as a modern, standards-based solution for enterprise-grade web components, leveraging Salesforce's strong market presence and developer community. The open source approach fosters community contributions and roadmap influence. The business benefits from Salesforce's brand trust, extensive developer ecosystem, and integration with its broader cloud offerings. The website supports this by providing detailed guides, community links, and source code access via GitHub. The absence of direct contact information suggests a focus on self-service developer engagement rather than direct sales through this site. The marketing ecosystem includes Google Analytics and Tag Manager for user insights, balanced with GDPR-compliant cookie consent. The company maintains a consistent branding strategy and leverages partnerships within the Salesforce ecosystem. Growth indicators include active GitHub repositories and community engagement. The site’s technical infrastructure supports scalability and performance, critical for enterprise adoption.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and a comprehensive cookie consent mechanism aligned with GDPR requirements. No exposed credentials, vulnerable libraries, or insecure forms were identified. However, the absence of explicit security headers in the HTML and lack of published security policies or incident response contacts represent areas for improvement. The WHOIS data is transparent and consistent with the business identity, reducing risk of domain spoofing or fraud. The site does not appear to be behind a WAF or present any blocking challenges, indicating open accessibility. Compliance with privacy regulations is evident through the privacy policy and cookie consent manager. The lack of a security.txt file or vulnerability disclosure policy may limit external security researcher engagement. Overall, the security risk is low but could be enhanced by formalizing security governance documentation and contact channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability disclosures.
  3. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  4. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  5. Enhance transparency by including terms of service and more detailed business contact information.

Technical notes

Notes

The website is built using modern web technologies including Lightning Web Components, leveraging native web standards for performance and compatibility. It integrates third-party services such as Algolia for search and OneTrust for cookie consent management, indicating a mature approach to user experience and compliance. Hosting on Salesforce infrastructure ensures reliability and speed. The site is mobile-optimized and accessible, with clean semantic HTML and CSS. No CMS was detected, suggesting a custom or static site generation approach. Performance is fast with minimal external dependencies. Technical risks are minimal but could be mitigated further by adding explicit security headers and formalizing security documentation.
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.
