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

Nationwide Heating & Cooling Ltd is a UK-based HVAC contractor specializing in heating, ventilation, refrigeration, and air conditioning engineering services for commercial and industrial sectors nationwide. The company positions itself as a leading service provider in the HVAC industry with a focus on quality and nationwide coverage. The website is professionally designed using the Wix platform, featuring structured data for local business identification and standard SEO metadata. However, the domain registration appears problematic as WHOIS queries fail due to domain naming rules violations, raising concerns about domain legitimacy despite the professional web presence. Technically, the site uses modern web technologies and is mobile optimized but lacks advanced security headers and privacy compliance mechanisms. Security posture is moderate with HTTPS enforced but missing explicit security policies and incident response contacts. Overall, the site is functional and informative but requires improvements in privacy, security disclosures, and domain registration legitimacy to enhance trust and compliance.

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

7 findings rated critical or high. Fix these first.

  1. 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

  2. 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';…

  3. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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 operates in the energy sector, providing HVAC contracting services primarily to commercial and industrial clients across the UK. Its business model is service-oriented, focusing on engineering solutions for heating and cooling systems. The website content and structured data indicate a small-sized enterprise with a localized physical address in Cramlington, England. The lack of detailed company registration or VAT information on the site limits deeper business intelligence insights. No partnerships or subsidiaries are evident from the website content. The company leverages Wix for digital presence, indicating a moderate level of digital maturity. Market positioning as a leading contractor suggests competitive advantages in service quality and geographic reach, though domain registration issues may impact credibility.

Security posture

The website enforces HTTPS, which is a fundamental security measure. However, it lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options, which are recommended best practices. No evidence of exposed sensitive data or vulnerable libraries was found in the HTML content. The absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and security readiness. No vulnerability disclosure or security.txt files were detected. The site does not appear to use extensive tracking or analytics, reducing privacy risks but also limiting user behavior insights. Overall, the security posture is moderate but could be significantly improved by implementing security headers, privacy compliance, and incident response mechanisms.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR and enhance user trust.
  2. Add standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to improve security posture.
  3. Resolve domain registration issues to ensure domain legitimacy and improve trustworthiness; consider registering a compliant domain name.
  4. Include clear contact information including company emails and phone numbers to facilitate communication and support.
  5. Establish and publish an incident response policy and contact channels to demonstrate security maturity and readiness.

Technical notes

Notes

The website is built on the Wix platform using Wix Thunderbolt framework, leveraging modern HTML5, CSS3, and JavaScript technologies. It uses JSON-LD structured data for SEO and local business identification. The site is mobile optimized and has a professional design with good navigation clarity. Performance is moderate, typical of Wix-hosted sites. However, the site lacks advanced accessibility features and comprehensive SEO optimizations. No third-party analytics or marketing tools were detected beyond Wix's standard scripts. The domain's WHOIS data is unavailable due to registration errors, which is a significant technical and trust concern. Hosting is provided by Wix, which generally offers reliable infrastructure but the domain issue may affect overall digital maturity.
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.
