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

Quadrangle Research Group Ltd is a well-established independent research and strategy consultancy based in London, UK, with over 30 years of experience. The company specializes in bespoke research, brand strategy, marketing, and data analytics services aimed at helping decision makers drive business growth and change. Their website reflects a professional and consistent brand image with comprehensive content and clear navigation. Technically, the site is built on WordPress with modern plugins for GDPR compliance, analytics, and performance optimization. Security posture is good with HTTPS and cookie consent mechanisms, though explicit security policies and incident response details are absent. The domain WHOIS data is missing, which raises some concerns about domain legitimacy relative to the company's claimed history. Overall, the website is trustworthy and professional but would benefit from enhanced transparency on security and domain registration.

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
    • 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

  2. 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

  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 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Quadrangle positions itself as a strategic research agency with a unique entrepreneurial mindset, targeting business decision makers who require actionable insights. Their business model is service-oriented consultancy with a focus on delivering bespoke solutions rather than off-the-shelf products. The company leverages a broad skill set including management consulting, brand strategy, and data analytics. Their market position is that of a niche, experienced player with a strong reputation, supported by testimonials and a detailed manifesto. The company maintains active social media presence on LinkedIn and YouTube, and partners with creative agencies for website development. The lack of WHOIS data suggests a recent domain registration or transfer, which should be monitored for continuity and trust.

Security posture

The website enforces HTTPS and uses a cookie consent management system compliant with GDPR, indicating a good baseline for privacy and security. However, no security headers were detected in the HTML content, and there is no visible security policy or incident response information. Third-party scripts such as Google Tag Manager and Gauges analytics are used, which require regular auditing to prevent vulnerabilities. The absence of a vulnerability disclosure policy and data protection officer contact reduces transparency. Overall, the security posture is moderate with room for improvement in explicit security documentation and header implementation.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  4. Consider adding a vulnerability disclosure policy and contact information for security issues.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS using modern plugins such as Contact Form 7 for forms, Complianz for GDPR cookie consent, and Swiper.js for interactive sliders. It uses lazy loading for images to improve performance and Google Tag Manager for analytics management. The site is mobile optimized with responsive design and good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with potential improvements in caching and script optimization. Hosting provider details are not explicitly found. Overall, the technical infrastructure is solid but could benefit from enhanced security headers and performance tuning.
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.
