Secure Access Service Edge (SASE) has quickly become a buzzword in the realm of network security. By converging network and security services into a unified, cloud-native model, SASE holds the promise of enhancing network efficiency and security. However, deploying this new architecture can be a complex task. This article provides a step-by-step guide for network architects on how to successfully deploy SASE.
The first step to deploying SASE is performing an initial assessment of your current network architecture. This involves a deep dive into your network infrastructure, understanding your traffic patterns, and identifying any bottlenecks or security gaps. You should also assess the level of cloud adoption in your organisation and the needs of your remote workforce.
Understanding your organisation’s current state will provide a benchmark against which you can measure the impact of SASE and help identify the areas that need the most attention.
Planning for SASE Deployment
Once you have a clear picture of your current network status, you can start planning for SASE deployment.
- Define Goals: What do you hope to achieve with SASE? This could be anything from reducing network complexity to improving security or enhancing performance for remote users.
- Choose a SASE Provider: Not all SASE providers are created equal. Ensure the one you choose offers a comprehensive set of security services, has a global network presence, and provides robust support.
- Develop an Implementation Timeline: SASE deployment should be done in phases to avoid disruption. Identify which parts of your network will transition to SASE first, and create a timeline for the rest.
With a clear plan in place, you’re now ready to implement SASE.
- Setup and Configuration: Work with your chosen SASE provider to set up the necessary infrastructure. This includes configuring the network and security services per your requirements.
- Testing: Before a full-scale rollout, conduct comprehensive testing to ensure everything works as expected. Check for any potential issues and fix them before proceeding.
Phased Rollout: Start deploying SASE gradually according to your plan. Monitor the process closely to quickly address any issues that arise.
Evaluating SASE Performance
After the deployment, it’s essential to evaluate the performance of the SASE architecture. Monitor the network’s speed, security, and reliability, and compare it to your initial assessment.
Remember, SASE deployment is not a one-and-done process. Regular evaluations will help you identify areas for improvement and ensure that your network continues to meet the needs of your organisation.
Deploying SASE can be a significant undertaking, but with careful planning, it can lead to a more efficient, secure, and agile network. By understanding your current network, planning for SASE deployment, implementing it correctly, and consistently evaluating its performance, you can successfully navigate the complexities of SASE deployment and reap its benefits.
