Deployment and management
- Management consoles: Centralized management via Symantec Endpoint Protection Manager (SEPM) or integrated management in enterprise suites. SEPM handles policy, client groups, updates, and reporting.
- Content/Update distribution: Hierarchical LiveUpdate points or direct from Symantec; supports peer distribution to reduce WAN usage.
- Policy design: Recommend layered policies — baseline protection (AV + firewall) for all devices, elevated policies for sensitive systems, and restrictive policies for high-risk groups.
- Rollout strategy: Phased rollout: pilot group → staged deployment (by OU/location) → monitoring and rollback plan. Use pre-deployment posture scans to identify conflicts.
- Agent sizing and exclusions: Tune scan schedules, exclusions for virtualization and backup software, and scan performance options to avoid resource contention.
- High availability: Configure redundant management servers and consider clustering or failover for SEPM where supported.
