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

2 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"

  2. GDPR outside view

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

    • 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

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

Discovery Energy, LLC dba Rehlko operates this platform as a medium-sized business in the energy sector, focusing on KOHLER generator sales and support through an authorized dealer network. The business model combines B2C and B2B elements, providing product information, dealer location services, and customer support. The company maintains active social media presence and integrates partner services such as warranty registration. The website content and navigation reflect a professional approach targeting homeowners and professionals seeking reliable generator solutions. The partnership ecosystem includes KOHLER and related service providers, supporting a comprehensive customer journey.

Security posture

The website exhibits a mature security posture with enforced HTTPS, Content Security Policy, and a consent management platform ensuring GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of additional security headers like X-Frame-Options and Strict-Transport-Security, as well as lack of published incident response or vulnerability disclosure policies, indicates moderate maturity. The site does not expose contact channels for security incidents, which could hinder timely response. Overall, the security practices are good but could be enhanced by formalizing policies and expanding header protections.

Recommendations

  1. Implement additional HTTP security headers such as X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security to strengthen defense-in-depth.
  2. Publish a security policy and incident response plan on the website to improve transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern React and Next.js stack, leveraging server-side rendering and static generation for performance. Integration with Microsoft Azure Maps provides advanced geolocation capabilities. The use of Contentful CMS enables flexible content management. Analytics are handled via Google Analytics 4 and Microsoft Clarity, with Osano managing cookie consent. Performance is moderate, with potential improvements in load times and resource optimization. The site is mobile-optimized with responsive design but could improve accessibility compliance. No hosting provider details were explicitly found, but the presence of Akamai-related scripts suggests CDN usage. Overall, the technical infrastructure is robust with opportunities for optimization and enhanced security.
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.
