The website reflects a professional and modern digital presence, leveraging multiple analytics and marketing technologies such as Google Tag Manager, Microsoft Application Insights, and Cookiebot for consent management. The technical infrastructure includes EPiServer CMS and integrates various third-party services for marketing and analytics. Security posture is generally strong with HTTPS enforced and bot protection via reCAPTCHA; however, the absence of explicit security policies and incident response contacts is noted.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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

The company targets the UK SME energy market with a business model centered on renewable energy supply and instant quoting services. Its market position is niche, focusing on sustainability and carbon reduction. The presence of LinkedIn and integration with major ad networks and analytics platforms indicates a mature marketing strategy. The absence of WHOIS data and terms of service may impact perceived credibility. No evidence of parent or subsidiary companies was found. The business operates in the energy sector with a medium-sized profile based on website sophistication and service scope.

Security posture

The website employs HTTPS and cookie consent management, indicating attention to security and privacy compliance. Use of reCAPTCHA helps mitigate automated abuse. However, no HTTP security headers were detected in the provided data, and no published security policy or incident response contacts were found. The absence of a security.txt file or vulnerability disclosure mechanism suggests room for improvement in transparency and incident readiness. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is good but could be enhanced by publishing formal security policies and improving header configurations.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to enhance security posture.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Consider adding a terms of service page to clarify user agreements and legal protections.
  5. Investigate and resolve the missing WHOIS registration data to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including EPiServer CMS, Google Tag Manager, Microsoft Application Insights, Cookiebot for consent management, and various marketing and analytics integrations. The site is mobile optimized with good accessibility and SEO practices. Performance is moderate, likely influenced by multiple third-party scripts. The use of Google Maps API and social media integrations enhances user engagement. No hosting provider information was discernible from the data. The technical implementation is solid but could benefit from performance optimization and enhanced security header deployment.
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.
