🚩 Key Lessons & Action Plan

Zero Trust & Privilege Hygiene

• Enforce least-privilege access
• Rotate machine keys, MFA everywhere
• Network segmentation and micro‑perimeters

Threat Detection & Incident Drill‑Readiness

• Deploy EDR/XDR with anomaly detection
• Monitor internal lateral movement and sandbox escapes
• Regular crisis simulations—including third-party compromise

Patch & Vendor Management

• Automate patching for critical systems (Chrome, SharePoint)
• Vet and audit vendor access policies
• Contractual clauses for swift breach disclosure

Data Protection & Brand Resilience

• Offline, immutable backups
• Data classification and shielding of high-risk identity assets
• Pre-prepared customer communication templates
