Transitioning from traditional WAN architectures to a modern Secure Access Service Edge (SASE) model is more than a technological shift—it’s a strategic evolution. Success depends on a well-planned, phased approach that minimizes disruption while maximizing return on investment. With careful planning, organizations can achieve secure, agile, and future-ready networks. Here are eight essential steps to guide your SASE migration.
1. Assemble a Cross-Functional Team
To ensure a smooth migration, break down silos between networking and security teams. Include key stakeholders like application owners and workplace transformation leaders for a comprehensive perspective. A unified team ensures seamless implementation and minimizes resistance during the transition.
2. Define Clear Objectives
Clearly articulate your goals for SASE adoption. Common objectives might include:
- Enabling remote work and work-from-anywhere flexibility.
- Simplifying global connectivity with secure, low-latency access.
- Eliminating backhauling and appliance sprawl by leveraging direct internet access (DIA).
- Optimizing performance for critical cloud applications.
Your objectives will shape the roadmap and guide decision-making throughout the project.
3. Assess Network and User Requirements
Not all sites or users have the same needs. Analyze your current network setup to determine:
- Connectivity options: Match each site with the right solution (e.g., MPLS for critical locations, broadband for smaller branches).
- User requirements: Decide between agent-based deployments or agentless browser connections.
- Application mapping: Link applications and users to SASE points of presence (PoPs) for high-performance access and minimal latency.
Understanding these needs will help you design a SASE network that delivers reliable performance across all users and locations.
4. Future-Proof Your Network
Consider how your SASE solution will scale with future business needs, including:
- Supporting global expansion or flexible work policies.
- Facilitating cloud migration or hybrid cloud strategies.
- Adapting to mergers, acquisitions, or other changes.
By aligning your SASE model with long-term objectives, you can ensure your network remains agile and resilient in the face of change.
5. Choose the Right Provider
Craft a Request for Information (RFI) that outlines your current network architecture and desired outcomes. Look for vendors who:
- Offer robust SASE architecture with proven scalability.
- Provide a comprehensive set of security and networking features.
- Deliver strong support and customer service.
An RFI helps narrow your options and sets the stage for a successful proof of concept.
6. Adopt a Phased Deployment Strategy
SASE is best implemented as a gradual transformation, not a one-time overhaul. Start small:
- Focus on specific sites, user groups, or applications.
- Transition as MPLS contracts expire or legacy hardware reaches end-of-life.
- Begin with remote workers or new locations before scaling across the organization.
This approach reduces costs, minimizes disruption, and allows you to measure success incrementally.
7. Build a Strong Business Case
When presenting SASE to leadership, emphasize its potential to:
- Simplify network complexity.
- Optimize costs compared to traditional WAN models.
- Strengthen security with centralized, cloud-native protections.
Use real-world case studies and data from early adopters to reinforce the value of SASE as a business investment.
8. Test, Evaluate, and Migrate
Conduct a Proof of Concept (PoC) with two or three shortlisted providers. Test each solution for up to 60 days, focusing on diverse use cases to ensure a thorough evaluation. Once you’ve identified the best fit, move forward with full-scale migration.
Unlock the Future of Networking with SASE
Migrating to a SASE architecture doesn’t have to be overwhelming. By following these eight steps—building a cross-functional team, defining clear objectives, and adopting a phased deployment—you can ensure a smooth transition and maximize the benefits of this modern approach.
