Designing Ashworth & Kane's whole collaboration estate — email, Teams, Slack, Zoom and SharePoint carrying privileged legal data — as an eight-layer collaboration defense stack: identity and tenant trust, email gateway, chat and meetings, file sharing and links, external collaboration, DLP and compliance, threat detection and response, and governance and lifecycle; with each layer's gap closed by design, from MFA that covered Exchange but not Teams or Slack, four subdomains without DMARC, anonymous Zoom joins and anyone-with-the-link sharing, to more than four thousand unreviewed guests, email-only DLP, chat attacks the SOC could not see and no metrics at all.
