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

HLS Structural Engineers Ltd is a UK-based consulting engineering firm specializing in structural and civil engineering services. The company operates primarily in the London and South East England regions, offering services ranging from residential structural design to large-scale commercial and industrial projects. Their website reflects a professional and established business with a clear focus on quality, reliability, and client satisfaction. The firm also actively recruits experienced structural engineers, indicating growth and operational stability. Technically, the website is built on WordPress using the Avada theme and several plugins including LayerSlider and Complianz GDPR for cookie management. The site employs modern web technologies such as jQuery and Google Analytics for tracking. The website is mobile-optimized and provides a good user experience with clear navigation and relevant content. However, some technical improvements could be made in security headers and explicit security policy disclosures. From a security perspective, the site uses HTTPS with a good SSL configuration and implements cookie consent mechanisms compliant with GDPR. No immediate vulnerabilities or exposed sensitive data were detected. However, the absence of security headers and incident response information suggests room for improvement in security posture. The WHOIS data for the domain is unavailable due to a registration error, which slightly impacts trust but does not detract from the professional nature of the website content. Overall, the website presents a credible and professional business presence with moderate technical maturity and a good privacy compliance framework. Strategic recommendations include enhancing security headers, publishing a security policy, and clarifying incident response contacts to strengthen trust and compliance further.

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

8 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

HLS Structural Engineers occupies a niche in the structural and civil engineering consulting market within the UK, focusing on both commercial and domestic sectors. Their competitive advantage lies in their regional presence across Hertfordshire, London, and the Isle of Wight, combined with a reputation for quality and reliability. The business model is service-oriented, relying on project-based consulting engagements. Revenue streams likely derive from engineering design, surveys, and remedial works. The target customer segments include property developers, commercial enterprises, and private homeowners. Growth indicators include active recruitment and satellite office expansion. The company maintains a professional partnership ecosystem, as evidenced by membership logos displayed on the site. Strategic observations suggest a stable, small-sized firm with potential for regional growth and increased market penetration.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR-compliant cookie consent mechanisms in place. The absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were found in the HTML content. The lack of a published security policy or incident response contact information indicates limited transparency in security governance. Compliance with GDPR is evident, but additional measures such as regular security audits and vulnerability management would enhance the security culture. Overall, the security posture is adequate for a small professional services website but could benefit from targeted improvements to align with best practices.

Recommendations

  1. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and preparedness.
  3. Regularly update WordPress core, themes, and plugins to minimize exposure to known vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider obtaining and displaying relevant industry certifications to strengthen trust and credibility.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Avada theme, layered with plugins such as LayerSlider for visual effects and Complianz for GDPR cookie management. The tech stack includes jQuery and Google Analytics for interactivity and analytics. The site is mobile-optimized with responsive design elements and good SEO metadata. Performance is moderate, with room for optimization in image loading and script management. The absence of advanced security headers and limited hosting information suggests potential technical debt. Opportunities exist to modernize the infrastructure by adopting HTTP/2, implementing caching strategies, and enhancing accessibility compliance. Technical risks are low but should be monitored through regular maintenance and security assessments.
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.
