How to Build and Migrate to a SASE Security Framework
Summary
A six-stage guide to SASE adoption recommends assessing infrastructure, piloting in controlled environments, migrating workloads gradually, redesigning policies, training teams, and continuously reviewing security and performance.
Key points
- Start with an infrastructure audit covering shadow systems, network topology, traffic flows, application dependencies, and compliance needs.
- Pilot SASE in limited environments for three to six months, setting performance baselines and validating access policies and operational procedures.
- Migrate workload groups in phases, keeping legacy systems available for one to three months so teams can roll back if problems arise.
- Redesign policies rather than mechanically copying legacy rules; apply least privilege and base access on identity, device posture, and application sensitivity.
- Train network and security teams in cloud-native architectures, automation, identity integration, and distributed policy management.
- Review policies quarterly and monitor application performance as user populations, traffic, and threats change.
- A comprehensive deployment can take one to two years and requires sustained investment and IT leadership commitment.
