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

Polar Heating & Hot Water Ltd is a small, local plumbing and heating service provider based in Radcliffe, Bury, UK. The company offers a wide range of services including boiler installation, repair, servicing, central heating, radiators, and gas appliance installation. With over 20 years of experience and accreditations such as Gas Safe registration and Worcester Bosch and Baxi approvals, the business positions itself as a reliable and professional service provider in the local market. The website content is focused on informing potential domestic and commercial clients about their services and contact options. From a technical perspective, the website uses basic HTML, CSS, and JavaScript without modern frameworks or CMS detected. The site lacks HTTPS and security headers, which negatively impacts its security posture. Mobile optimization and accessibility are basic, and SEO practices are minimal. There is no evidence of analytics or tracking technologies, and no privacy or cookie policies are present, indicating low privacy compliance. Security-wise, the absence of HTTPS and security headers, along with no visible incident response or vulnerability disclosure policies, suggests a low security maturity level. The website does not expose sensitive data but lacks modern security best practices. The WHOIS lookup failed due to an invalid query for the 'www' subdomain, limiting domain registration verification and reducing trustworthiness from a domain perspective. Overall, the website is functional and provides relevant business information but requires significant improvements in security, privacy compliance, and technical modernization to enhance trust and protect users. Strategic recommendations include implementing HTTPS, adding security headers, publishing privacy and cookie policies, and improving mobile and accessibility features.

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

9 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. DNS health

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

    • High

      Domain Expires Soon

      Domain expires in 24 days

      What to do: Renew domain registration before expiration

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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

Polar Heating & Hot Water Ltd operates as a small, family-run business in the energy sector, specifically plumbing and heating services. Their competitive advantages include over 20 years of experience, Gas Safe registration, and manufacturer accreditations. The business model is service-oriented, targeting domestic and commercial customers in Bury and surrounding areas. Revenue streams likely derive from installation, repair, servicing, and certification services. The company maintains a local reputation with trust signals such as insurance and qualifications. The website indicates a limited digital marketing presence with no evident partnerships or subsidiaries. Growth indicators are not explicit, but the business emphasizes reliability and professionalism. The partnership with web design provider websiteswotwork.co.uk is noted but not a business partner. Overall, the company appears stable but could benefit from enhanced digital presence and compliance to support growth.

Security posture

The current security posture of the website is low. The absence of HTTPS is a critical vulnerability that exposes users to data interception risks. No security headers such as Content-Security-Policy or X-Frame-Options are present, increasing susceptibility to common web attacks. There is no visible privacy or cookie policy, indicating non-compliance with GDPR and related regulations. No incident response or vulnerability disclosure mechanisms are provided, limiting the ability to manage security incidents effectively. The website does not use modern security frameworks or demonstrate adherence to recognized standards. While no sensitive data exposure or malware was detected, the lack of basic security controls represents a significant risk to business operations and customer trust. Immediate remediation is recommended to improve security maturity and compliance.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all website traffic.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  4. Establish an incident response plan and provide clear contact channels for security issues.
  5. Modernize the website’s technical stack to improve performance, accessibility, and mobile responsiveness.

Technical notes

Notes

The website is built using basic HTML, CSS, and JavaScript without any detected CMS or modern frameworks. The meta charset is set to windows-1252, which is outdated and may cause encoding issues. The site lacks HTTPS and security headers, which are critical for secure web operations. Performance is moderate but could be improved with modern optimization techniques. Mobile optimization is basic, with a mobile redirection script pointing to a separate mobile page rather than responsive design. Accessibility features are minimal, and SEO practices are basic with meta description and keywords present but no structured data or Open Graph tags. No analytics or tracking scripts are detected, indicating limited digital marketing integration. Hosting provider and infrastructure details are not discernible from the content.
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.
