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

Fletchers Engineering is a well-established UK-based engineering company specializing in HVAC fabrication, installation, and maintenance services. With over 30 years of industry experience, the company serves a diverse range of sectors including energy, manufacturing, hospitality, and government. Their website reflects a professional and comprehensive presentation of their services, supported by multiple industry accreditations and certifications, positioning them as a reputable player in their market segment. Technically, the website is built on WordPress with modern JavaScript libraries such as jQuery and Slick Slider, and integrates key tools like Google Analytics, Hotjar, and Google reCAPTCHA for analytics and security. The site is mobile-optimized and includes GDPR-compliant cookie consent mechanisms, indicating a mature digital presence. However, some improvements in accessibility and security headers could enhance the technical posture. From a security perspective, the site enforces HTTPS and uses reCAPTCHA to protect forms, but lacks explicit security policies and incident response information. The WHOIS data is unavailable due to a query on the subdomain rather than the registered domain, which slightly reduces trustworthiness from a domain registration standpoint. Overall, the security posture is good but could benefit from additional transparency and technical hardening. The overall risk assessment is moderate-low, with the main concerns being the incomplete WHOIS data and absence of published security policies. Strategic recommendations include verifying domain registration details, implementing security.txt and incident response pages, and enhancing HTTP security headers to improve trust and 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

7 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. 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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 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.

Business context

Business profile

Fletchers Engineering operates in a competitive engineering services market, leveraging over three decades of experience and a broad service portfolio including HVAC systems, offsite manufacturing, and steel fabrication. Their business model focuses on providing end-to-end engineering solutions with a strong emphasis on quality, safety, and reliability. The company targets commercial and industrial clients across the UK, supported by a flexible nationwide service and ongoing maintenance offerings. Their partnership ecosystem includes recognized industry accreditations, enhancing credibility and market positioning. The website's content strategy, including case studies and news updates, indicates active engagement with clients and prospects, supporting growth and brand awareness.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement and use of Google reCAPTCHA to mitigate spam and abuse on contact forms. Cookie consent management aligns with GDPR requirements, reflecting compliance awareness. However, the absence of explicit security policies, incident response contacts, and security.txt files limits transparency and preparedness communication. No critical vulnerabilities or exposed sensitive data were detected in the content. The use of third-party analytics and tracking services is disclosed via cookie consent, but continuous monitoring of these integrations is advisable. Enhancing HTTP security headers and publishing formal security documentation would elevate the security maturity and stakeholder trust.

Recommendations

  1. Verify and correct WHOIS domain registration queries to obtain accurate domain ownership data.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Implement security.txt file to facilitate vulnerability disclosures and responsible reporting.
  4. Add advanced HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  5. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.

The website is powered by WordPress CMS, utilizing a modern tech stack including jQuery, Slick Slider, and Google services for analytics and security. The site is mobile responsive with good SEO optimization and structured metadata including JSON-LD and Open Graph tags. Performance is moderate with asynchronous loading of scripts and optimized images. Accessibility features are basic but present. The use of GDPR-compliant cookie consent and reCAPTCHA indicates attention to privacy and security. Opportunities exist to improve technical robustness by enhancing accessibility, adding security headers, and optimizing performance further to reduce load times and improve user experience.
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.
