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

Capital Power is a large, publicly traded independent power producer headquartered in Edmonton, Alberta, Canada, operating approximately 12 GW of generation capacity across North America. The company focuses on natural gas, renewables, and battery energy storage solutions, serving investors, partners, and communities with reliable and clean energy. The website demonstrates a mature digital presence with comprehensive investor relations, media releases, and sustainability information. Technically, the site is built on WordPress with modern libraries and frameworks, optimized for SEO and mobile use. Security posture is good with HTTPS and secure forms, though some security headers and explicit incident response information are missing.

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

9 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  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
    • 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

  3. 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 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

Capital Power holds a strong market position as a leading independent power producer in North America, leveraging a diversified portfolio of energy assets. Their business model centers on utility-scale power generation and energy marketing, targeting institutional investors and energy consumers. The company emphasizes sustainability and innovation, aligning with market trends towards lower-carbon energy. The website's investor-focused content and media presence indicate active engagement with stakeholders. The absence of detailed WHOIS data is a minor anomaly but does not undermine the company's established reputation. Growth indicators include recent acquisitions and long-term energy agreements, positioning Capital Power for continued expansion.

Security posture

The website employs HTTPS and secure form submissions, indicating a baseline security maturity. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published vulnerability disclosure policy or security.txt file limits transparency in incident response readiness. Privacy compliance is partial; while a privacy policy exists, cookie consent mechanisms are missing, which may pose compliance risks under GDPR. Overall, the security posture is solid but could be enhanced by adopting additional best practices and explicit security communications.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Deploy a cookie consent banner or mechanism to ensure GDPR and privacy regulation compliance.
  3. Publish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Enhance contact pages with dedicated security contact emails to facilitate reporting of security issues.
  5. Investigate and resolve the missing WHOIS data to improve domain registration transparency and trust.

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.
