Risk levelMedium

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

Heelman Ltd is a family-owned precision engineering company specializing in CNC subcontract machining, prototype parts, and small batch manufacturing. Established in 1982, the company serves a diverse range of industries including automotive and decorative manufacturing, positioning itself as a reliable small to medium batch specialist with competitive lead times. The website reflects a professional and consistent brand image, targeting manufacturing businesses requiring high-quality precision turned parts. Technically, the website is built on the One.com Web Editor platform, with moderate performance and basic mobile optimization. Security posture is limited, with no detected security headers or privacy policies, and the WHOIS data for the domain is unavailable due to a domain registration error, which raises some concerns about domain legitimacy. Overall, the website provides clear contact information and business details but lacks comprehensive privacy and security compliance 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

10 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

  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
    • 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

  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

Heelman Ltd operates in the manufacturing sector, focusing on precision turned parts and CNC machining services. The business model is subcontracting with an emphasis on small batch and prototype work, catering to clients needing high precision and quick turnaround. The company leverages its family-owned heritage since 1982 as a trust signal. The website does not reveal revenue streams or partnerships but shows a clear focus on quality and customer service. The absence of social media and limited digital marketing tools suggests a traditional or localized market approach. The company’s competitive advantage lies in its skilled workforce, modern machinery, and ability to handle diverse industries from automotive to decorative items.

Security posture

The website’s security posture is basic with no visible security headers such as Content-Security-Policy or X-Frame-Options, and no privacy or cookie policies are present. HTTPS usage is assumed but not explicitly confirmed in the data. The WHOIS data is missing due to domain registration issues, which impacts trustworthiness. No incident response or vulnerability disclosure information is provided. The presence of a SiteWit tracking pixel indicates some level of user tracking but no advanced security or privacy compliance mechanisms are evident. Overall, the security maturity is low, exposing the business to potential compliance and trust risks.

Recommendations

  1. Implement and enforce HTTPS with strong SSL/TLS configuration and verify via external tools.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and improve user trust.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a security.txt file and provide incident response contact information for transparency.
  5. Resolve domain registration issues to ensure WHOIS data is accurate and consistent with business identity.

Technical notes

Notes

The website is built using the One.com Web Editor CMS and hosted on One.com infrastructure. The technology stack includes standard HTML5, CSS3, and JavaScript with no advanced frameworks detected. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with proper meta tags and Open Graph tags present. The site uses a SiteWit analytics tracking pixel for user data collection. There are no visible forms on the homepage, reducing data collection risk but also limiting user interaction. The technical debt appears low but modernization opportunities exist in security and privacy 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.
