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

CTS Security is a well-established security company based in Norfolk, UK, specializing in the installation and maintenance of intruder alarms, fire alarms, CCTV, and access control systems. With over 50 years of experience, the company serves a diverse clientele including commercial, domestic, and public sector customers across East Anglia and beyond. The website reflects a professional and trustworthy business with clear service offerings and client endorsements. Technically, the website employs modern analytics and marketing tools such as Google Analytics, Facebook Pixel, and LiveChat, indicating a mature digital presence. Security-wise, the site uses HTTPS and secure forms but lacks explicit security headers and published security policies, which could be improved. The WHOIS data is unavailable due to domain naming rules violations, which introduces some uncertainty about domain legitimacy, though the website content itself is consistent and professional. Overall, the site presents a solid business with room for enhanced security transparency and compliance documentation.

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. 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. 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 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';…

  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

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

CTS Security holds a strong market position as Norfolk's leading security provider with a broad sector reach including government, commercial, and domestic markets. Their business model focuses on security system installation and maintenance, leveraging long-term client relationships and a reputable brand evidenced by client logos and accreditations. The company targets a wide range of industries such as retail, manufacturing, education, and agriculture. Their digital ecosystem includes partnerships with marketing and analytics platforms, enhancing customer engagement and lead generation. The absence of detailed WHOIS data suggests the domain may be a subdomain or configured unusually, which should be clarified for trust. The company demonstrates stable growth indicators and a professional online presence, supporting credibility in their sector.

Security posture

The website demonstrates a good security posture with enforced HTTPS, secure form handling, and cookie consent mechanisms aligned with GDPR. However, it lacks advanced security headers like Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. There is no visible security policy or incident response information, nor a vulnerability disclosure program, which are important for transparency and trust. No vulnerabilities or exposed sensitive data were detected in the content. The use of third-party analytics and marketing tools is standard but requires ongoing monitoring for privacy compliance. Overall, the security maturity is moderate with opportunities for improvement in policy publication and technical hardening.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Establish a vulnerability disclosure program or publish a security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Clarify domain registration details and ensure WHOIS information is accurate and consistent with business claims to improve trust.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Facebook Pixel, Google Analytics, LiveChat, and Google Maps API, indicating a well-integrated digital marketing and customer engagement infrastructure. The site loads CSS and JavaScript assets efficiently and is mobile optimized with responsive images and layouts. However, no CMS or hosting provider information is explicitly detected. Performance is moderate with room for optimization. Accessibility is basic, suggesting potential improvements in semantic markup and ARIA attributes. SEO is well addressed with proper meta tags and Open Graph data. The absence of explicit security headers is a technical gap. Overall, the technical implementation supports business goals but could benefit from enhanced security and accessibility modernization.
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.
