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

Avison Young UK is a large, professional commercial real estate advisory firm offering a wide range of services including property sales, leasing, management, consulting, and investment advisory. The website is well-designed, mobile-optimized, and rich in relevant content targeting investors, occupiers, and public sector clients in the UK real estate market. Technically, the site is built on the Liferay CMS platform and integrates modern analytics and marketing tools such as HubSpot and Google Tag Manager. Security posture is strong with HTTPS enforced and appropriate security headers, though explicit incident response and vulnerability disclosure information is not publicly available.

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

2 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

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

Avison Young UK operates in the commercial real estate sector with a comprehensive service portfolio spanning occupier and investor services, market intelligence, and sector-specific expertise. The firm targets a broad audience including investors, occupiers, and public sector leaders. The website content and structure indicate a mature business model with strong branding consistency and trust signals such as awards and thought leadership. The company leverages partnerships and global connections, as evidenced by related domains and career platform integration. The business is positioned as a key player in the UK commercial real estate market with a large operational footprint.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and multiple security headers implemented. Cookie consent mechanisms and privacy policies indicate compliance with GDPR and related regulations. However, the absence of publicly available incident response contacts and vulnerability disclosure policies suggests areas for improvement in transparency and security maturity. No obvious vulnerabilities or exposed sensitive data were detected in the analysis. The use of reputable third-party analytics and marketing tools is balanced with privacy compliance measures.

Recommendations

  1. Publish a dedicated vulnerability disclosure policy and security.txt file to enhance transparency and encourage responsible reporting.
  2. Provide clear incident response contact information, such as a security or abuse email address, to improve trust and readiness.
  3. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.
  4. Consider obtaining and displaying relevant security certifications or compliance attestations to strengthen trust signals.
  5. Enhance technical SEO and accessibility features to improve user experience and search engine rankings.

Technical notes

Notes

The website is built on the Liferay CMS platform, utilizing modern JavaScript libraries including React and jQuery. It integrates third-party services such as HubSpot for marketing and analytics, Google Tag Manager for tag management, and Vimeo for video content. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with combined and minified resources served via CDN. The technical implementation follows best practices for security and privacy, though there is room for improvement in incident response and vulnerability disclosure transparency.
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.
