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

Henderson.S.Services Ltd is a UK-based engineering company specializing in pipework, insulation, fabrication, and installation services across various industrial sectors including chemical, pharmaceutical, food and beverage, and offshore industries. The company emphasizes quality and has longstanding relationships with major blue chip clients. The website is professionally designed using WordPress CMS and incorporates modern web technologies such as Google Tag Manager and CookieScript for analytics and privacy compliance. Security posture is generally good with HTTPS enforced and cookie consent implemented, though the absence of security headers and lack of publicly available security policies indicate room for improvement. The WHOIS data is unavailable due to a domain registration error, which raises some concerns about domain legitimacy despite the professional online presence. Overall, the website reflects a credible and established business with moderate technical maturity and privacy 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

6 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. 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

  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

The company operates in the manufacturing and industrial engineering sector, targeting B2B clients requiring specialized pipework and insulation solutions. Its competitive advantage lies in over 30 years of experience, ISO 9001 certification, and a diverse service portfolio tailored to high-profile clients. The business model focuses on providing comprehensive engineering services including fabrication and installation, supported by a professional website that highlights certifications and client relationships. The absence of social media presence suggests a traditional business approach. The company appears medium-sized with a stable market position in the UK industrial sector.

Security posture

The website employs HTTPS and cookie consent mechanisms, indicating awareness of basic security and privacy requirements. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is published, which could hinder rapid response to security issues. The WHOIS data anomaly is a notable risk factor, potentially impacting trust and domain ownership verification. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could benefit from enhanced headers, published policies, and domain registration transparency.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve site security.
  2. Publish a security policy and incident response plan on the website to enhance transparency and preparedness.
  3. Investigate and resolve the domain WHOIS registration issue to ensure domain legitimacy and trustworthiness.
  4. Add a security.txt file to facilitate vulnerability reporting and improve security communication.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and reduce risks.

Technical notes

Notes

The website is built on WordPress 4.9.24 with a combination of jQuery, Modernizr, and Picturefill for frontend functionality. Google Tag Manager and Google Analytics are used for tracking, integrated with a CookieScript consent banner ensuring GDPR compliance. The site is mobile responsive with good navigation and SEO practices. Performance is moderate, with potential improvements in loading speed and accessibility. The absence of security headers and outdated WordPress version (4.9.24) may pose security risks. Hosting provider details are not evident from the HTML content. Overall, the technical infrastructure is stable but would benefit from modernization and enhanced security configurations.
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.
