Technically, the website is built on WordPress using the Divi theme, with integrations of modern marketing and analytics tools including Google Tag Manager, Facebook Pixel, and Hotjar. The site is mobile optimized and SEO friendly, though accessibility is basic. Security posture is good with HTTPS enforced but lacks some security headers and cookie consent mechanisms.

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

6 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

  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

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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

Superwarm operates in the energy sector, targeting homeowners and property managers in central Scotland seeking reliable and energy-efficient gas central heating solutions. Their competitive advantages include accredited installers, no deposit policy, fixed price quotes, and a dedicated aftercare service. The company leverages partnerships with major boiler manufacturers and maintains a strong local reputation evidenced by multiple positive customer testimonials. Revenue streams likely come from boiler sales, installation services, servicing contracts, and repair work. The company maintains an active online presence with social media engagement and uses digital marketing tools to generate leads. Growth indicators include a comprehensive service area covering central Scotland and a focus on energy savings and environmental benefits. The partnership ecosystem includes recognized industry certifications and manufacturer accreditations, enhancing trust and market positioning.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. The lack of a cookie consent mechanism and explicit GDPR compliance statements indicates gaps in privacy compliance. No incident response or security policy information is published, which limits transparency and preparedness perception. The use of multiple third-party tracking and marketing scripts introduces potential privacy risks if not properly managed. The WHOIS data unavailability is a concern for domain legitimacy verification but does not directly impact website security. Overall, the security posture is adequate for the business type but could be improved by implementing recommended headers, privacy controls, and publishing security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and improve user privacy transparency.
  3. Publish a security policy and incident response plan on the website to demonstrate security governance and readiness.
  4. Regularly audit and update third-party scripts to minimize vulnerabilities and privacy risks.
  5. Investigate and resolve WHOIS data issues with Nominet to improve domain registration transparency and trust.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Divi theme, which provides a flexible and responsive design. It integrates several JavaScript libraries and marketing tools such as jQuery, Google Tag Manager, Facebook Pixel, Hotjar, and LeadConnectorHQ chat widget, indicating a mature digital marketing infrastructure. Performance is moderate with some optimization opportunities in accessibility and security headers. SEO is well addressed with Yoast SEO plugin usage and proper meta tags including Open Graph and JSON-LD structured data. The site is mobile optimized and provides a good user experience with clear navigation and professional content. Technical risks include reliance on multiple third-party scripts and lack of some security best practices, which should be addressed to reduce attack surface and improve compliance.
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.
