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

Black Isle Renewables Ltd is a Scotland-based company specializing in environmentally-friendly renewable heating systems, including ground and air source heat pumps, solar energy, and underfloor heating. Recently rebranded and merged into aes renewables, the company positions itself as a leading provider in the Scottish renewable energy market, offering design, installation, maintenance, and servicing solutions. Their website is professionally designed, mobile-optimized, and provides comprehensive information about products, services, grants, and case studies, supporting a strong market presence. Technically, the website is built on the Squarespace platform, leveraging modern web technologies such as jQuery, Google Tag Manager, Google Analytics, and YouTube embeds. The site demonstrates good SEO practices and moderate performance, with a cookie consent mechanism indicating GDPR compliance. Security headers are not fully detailed in the HTML, but HTTPS is enforced via Squarespace hosting, providing a good baseline security posture. Security-wise, no critical vulnerabilities or exposed sensitive data were detected. The absence of detailed WHOIS data is due to privacy protection, which is justified for this business type. The company maintains trust indicators such as MCS accreditation, customer testimonials, and case studies. Overall, the website and business exhibit a solid security and compliance posture with room for improvement in security header implementation. The overall risk assessment is low, with recommendations to enhance security headers and maintain regular audits of third-party scripts. The company’s digital maturity is moderate to good, supporting its business objectives effectively.

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 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. 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

  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 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

Black Isle Renewables operates in the renewable energy sector, targeting homeowners and businesses in Scotland seeking sustainable heating solutions. Their competitive advantage lies in their comprehensive service offering, combining product supply, installation, and maintenance with expertise in grants and incentives. The recent merger with AES Solar and rebranding to aes renewables indicate strategic growth and market consolidation. Revenue streams likely include product sales, installation fees, and maintenance contracts. The company maintains active social media channels and a professional web presence, supporting customer engagement and lead generation. Their partnership ecosystem includes AES Solar and related renewable energy entities, enhancing their service portfolio and market reach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No incident response or security policy pages were found, indicating potential gaps in formal security governance documentation. The cookie consent banner and privacy policy reflect GDPR awareness, but no dedicated vulnerability disclosure or security.txt files were detected. Overall, the security posture is adequate for the business scale but would benefit from enhanced security controls and documented policies to improve resilience and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy to mitigate common web vulnerabilities.
  2. Develop and publish a formal security policy and incident response plan accessible via the website to enhance transparency and preparedness.
  3. Regularly audit and update third-party scripts and integrations to prevent supply chain vulnerabilities.
  4. Enhance privacy compliance by detailing data retention policies and providing clear user data management options.
  5. Strengthen trust by adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is hosted on Squarespace, utilizing its CMS capabilities and standard integrations such as Google Tag Manager, Google Analytics, and YouTube embeds for multimedia content. The use of jQuery and asynchronous script loading supports a responsive user experience. Performance is moderate, with good mobile optimization and basic accessibility features. SEO is well addressed through meta tags and structured data (JSON-LD). The technical infrastructure is modern and stable, though improvements in security headers and accessibility compliance could further enhance the site’s robustness and user inclusivity.
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.
