Risk levelMedium

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

Generac Power Systems, Inc. is an established enterprise specializing in manufacturing reliable and environmentally-friendly power generation equipment including home standby generators, portable power solutions, solar and battery systems, and EV chargers. The company targets residential and industrial customers seeking dependable energy solutions. Their website reflects a mature digital presence with modern technologies such as Vue.js, Amplitude analytics, and Google Tag Manager, supporting a good user experience and performance. Privacy and cookie policies are implemented with consent mechanisms, indicating compliance with data protection regulations. Security posture is strong with HTTPS enforcement and security headers, though explicit security policies and incident response information are not publicly available. The absence of WHOIS data is a notable gap but does not detract from the overall legitimacy suggested by the website content and integrations.

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

3 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 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

Generac holds a leading market position in the energy sector, focusing on power systems for residential and industrial markets. Their business model centers on manufacturing and selling energy equipment with additional services such as dealer locator and financing options. The company has a consistent brand presence and leverages third-party tools for customer reviews and analytics. The website's comprehensive content and clear navigation support customer engagement and sales funnel activities. No direct contact emails or phone numbers are exposed, relying on forms for lead capture. The company appears to maintain good privacy compliance and marketing transparency.

Security posture

The website demonstrates a solid security posture with HTTPS, security headers, and no visible vulnerabilities or exposed sensitive data. However, the lack of published security policies, incident response contacts, or vulnerability disclosure mechanisms limits transparency and readiness perception. The use of multiple third-party scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the security maturity is good but could be enhanced by publishing explicit security governance information and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security contact emails (e.g., security@generac.com) for reporting issues.
  4. Regularly review and update third-party scripts to minimize supply chain vulnerabilities.
  5. Enhance data retention and privacy disclosures to align with best practices and regulations.

Technical notes

Notes

The website uses a modern tech stack including Vue.js for frontend interactivity, jQuery for legacy support, and Swiper.js for UI components. Analytics are handled via Amplitude and Google Tag Manager, with Optimizely for experimentation and Bazaarvoice for customer reviews. The site is mobile optimized with responsive design and accessibility features. Performance is moderate, with deferred and async loading of scripts. No CMS or hosting provider is explicitly identified. The technical implementation supports a professional and scalable digital presence with room for optimization in performance and security transparency.
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.
