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

GCW is a London-based property consultancy specializing in town centre retail property services. The company offers strategic advice to owners, investors, occupiers, and stakeholders, positioning itself as a trusted advisor in the retail property market. Their website reflects a professional and client-focused approach, featuring detailed case studies, client testimonials, and a comprehensive service offering. The target audience includes property owners, investors, and stakeholders interested in retail and town centre property opportunities. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, jQuery, and integrates Google Analytics and Tag Manager for tracking. The site is mobile-optimized with good SEO practices and a cookie consent mechanism compliant with GDPR. However, there is room for improvement in security headers and explicit security policy disclosures. Security posture is solid with HTTPS enforced and secure form handling, but lacks advanced HTTP security headers. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong with clear privacy and cookie policies and user consent mechanisms. The WHOIS data for the www subdomain is unavailable due to domain naming rules, but the main domain gcw.co.uk is active and legitimate. Overall, GCW's website presents a trustworthy and professional digital presence with moderate technical sophistication and good privacy compliance. Strategic improvements in security headers and incident response disclosures would enhance their security posture and trustworthiness.

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

5 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  2. 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

  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 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';…

  4. 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

Business profile

GCW operates in the real estate sector, focusing on retail property consultancy within London town centres. Their business model revolves around providing expert advice and bespoke property solutions to a diverse client base including owners, investors, occupiers, and stakeholders. The company leverages data-driven market insights and strategic partnerships to maintain a competitive edge. Revenue streams likely include consultancy fees, project management, and property search services. The presence of detailed case studies and client testimonials indicates a mature client relationship management approach. The company maintains an active social media presence on LinkedIn, Twitter, and Instagram, supporting brand visibility and client engagement. Growth indicators include a broad service portfolio and emphasis on evolving town centre landscapes.

Security posture

GCW demonstrates a moderate to good security maturity level. The website enforces HTTPS and uses secure form validation techniques. A cookie consent banner with granular options indicates GDPR awareness and compliance. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests potential areas for enhancement. No incident response or security policy pages were found, which could limit transparency and preparedness. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate for a consultancy website but could benefit from implementing additional security best practices and formal incident response mechanisms.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Conduct regular third-party script audits to ensure no vulnerable or malicious libraries are included.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and regularly update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS3, and JavaScript with jQuery and AOS for animations. Google Analytics and Google Tag Manager are integrated for analytics and tracking. The site uses client-side form validation with jQuery Validation and unobtrusive validation scripts. Performance is moderate with video background and multiple scripts, but mobile optimization is good. No CMS or hosting provider information was detected. SEO is supported by proper meta tags, Open Graph tags, and JSON-LD structured data describing the business. The site lacks advanced security headers and could improve accessibility compliance. Overall, the technical infrastructure is solid but could be modernized with enhanced security and performance optimizations.
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.
