Xen Bilişim Deployment Process
- 1. Discovery & sizing: Current environment, user count, OS/cloud distribution and compliance requirements analysed; correct SKU and licence count proposed.
- 2. Pilot deployment: A 10-25 device subset goes live; integration with existing security stack tested; alerting + reporting configured.
- 3. Full rollout: Phased rollout across all endpoints; policy templates applied; user training and IT runbook delivered.
- 4. Optimisation & follow-up: 90-day post-launch tuning: false-positive triage, policy hardening, KPI review and quarterly health-checks.
Typical end-to-end timeline: 2-4 weeks (varies by user count and integration scope).
