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

Sempra is a major North American energy infrastructure company providing safe, reliable, and affordable energy to nearly 40 million consumers. The company focuses on electrification, resilient energy systems, and next-generation technologies, positioning itself as a leader in energy innovation and infrastructure development. Their website reflects a mature enterprise with strong market presence and recognized corporate responsibility. Technically, the site is built on Drupal 10 with modern web technologies, optimized for performance and mobile use, and incorporates security best practices such as HTTPS, reCAPTCHA, and Cloudflare services. However, the absence of visible cookie consent and detailed security policies indicates room for improvement in privacy compliance. The WHOIS data is unavailable or protected, which is common for large corporations but slightly reduces transparency. Overall, the website is professional, trustworthy, and well-maintained, supporting Sempra's business credibility and market position.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

Sempra operates in the energy sector with a focus on utility services, LNG infrastructure, and energy network modernization. The company targets investors, industry stakeholders, and the general public interested in energy solutions. Their business model includes ownership and operation of energy networks and strategic partnerships for LNG supply. Recognitions from Fortune, Newsweek, and TIME underscore their corporate reputation. The website supports investor relations, career opportunities, and news dissemination, indicating a comprehensive stakeholder engagement strategy. Partnerships with recruiting platforms and investor portals enhance operational reach. The company’s subsidiaries and related domains reflect a diversified energy infrastructure portfolio.

Security posture

The website demonstrates a strong security posture with enforced HTTPS, use of Google reCAPTCHA to prevent automated abuse, and Cloudflare security services. Security headers and nonce usage for inline scripts indicate attention to mitigating common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy, incident response contact, or vulnerability disclosure page suggests gaps in transparency and formal security communication. The absence of a cookie consent mechanism also impacts privacy compliance. Overall, the site is secure but could enhance user trust by publishing more explicit security and privacy information.

Recommendations

  1. Implement a visible cookie consent banner to comply with privacy regulations and improve user trust.
  2. Publish a dedicated security policy and incident response page to enhance transparency and preparedness.
  3. Add a vulnerability disclosure or security.txt file to facilitate responsible security reporting.
  4. Provide clear contact information for security incidents and data protection officer to comply with GDPR and similar regulations.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

It uses Cloudflare for CDN and security services, including Zaraz for tag management. Google Tag Manager and reCAPTCHA are integrated for analytics and bot protection. The site is mobile-optimized with responsive images and accessible navigation. Performance appears fast with asynchronous script loading and lazy loading of images. SEO is supported by proper meta tags and Open Graph data. Accessibility features like skip links and ARIA labels are present. Overall, the technical infrastructure is modern, robust, and well-implemented, supporting a high-quality user experience.
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.
