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

Duscovent Engineering Limited is a UK-based specialist in air pollution control systems, providing design, manufacture, installation, and maintenance services primarily for industrial clients across Britain and Europe. The company has a long-standing market presence with a domain registered since 1997, indicating established operations. Their key services include LEV system maintenance, ventilation systems, and supply of spares. The website is built on WordPress with a modern tech stack including Bootstrap and jQuery, offering a good user experience with clear navigation and mobile optimization. Security posture is adequate with HTTPS and anti-spam measures but lacks advanced security headers and incident response disclosures. Privacy compliance is partially met with a GDPR policy but no cookie consent mechanism. Overall, the site reflects a professional small business with moderate digital maturity and a solid trust profile.

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

4 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. 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

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 energy and manufacturing sectors, targeting industrial clients needing air pollution control and ventilation solutions. Their business model is B2B, focusing on engineering and maintenance services. The presence of P601 qualified engineers and a comprehensive GDPR policy indicates professionalism and regulatory awareness. The website content is relevant and consistent with their market positioning. However, the absence of phone numbers, emails, and social media links on the homepage may limit direct customer engagement. The company appears to maintain a focused niche with no evident partnerships or subsidiaries listed on the site.

Security posture

The website uses HTTPS and employs CleanTalk anti-spam protection, which are positive security indicators. However, the lack of security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No incident response or vulnerability disclosure policies are published, which could hinder timely handling of security incidents. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The security score is moderate, with recommendations to implement additional headers and publish security policies to enhance trust and compliance.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve security posture.
  2. Add a cookie consent banner and detailed cookie policy to ensure full GDPR compliance.
  3. Publish an incident response policy and provide a dedicated security contact email to improve transparency and readiness.
  4. Include explicit contact details such as company phone numbers and emails on the website to enhance customer trust and engagement.
  5. Regularly update WordPress core and plugins to mitigate potential vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website is built on WordPress 6.8.6 with Bootstrap and jQuery frameworks, providing a responsive and user-friendly interface. The use of CleanTalk anti-spam plugin indicates attention to spam protection. Performance is moderate with no major issues detected in the HTML content. SEO optimization is basic with meta tags present but no advanced structured data or Open Graph tags found. Accessibility features are minimal but functional. Hosting provider details are limited to registrar information (123-Reg Limited). There is an opportunity to improve technical robustness by adding security headers, enhancing SEO with structured data, and implementing analytics for better user insights.
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.
