The emergence of Secure Access Service Edge (SASE) has transformed the network security landscape, promising improved efficiency and advanced security. For network architects navigating the complexities of SASE deployment, understanding the process, its impact, and learning from others’ experiences can be invaluable. This blog post explores these aspects of successful SASE deployment.
SASE Deployment Background
As businesses increasingly move towards cloud-based solutions and remote work, the demand for secure and efficient networks has soared. Traditional network architectures, with their focus on perimeter security, struggle to keep pace with these changing dynamics. SASE, a converged network and security model, emerges as the solution.
SASE is a cloud-native architecture that integrates wide area networking (WAN) capabilities and network security services into a single platform. It provides secure and fast network access, irrespective of the user’s location, making it ideal for today’s distributed workforce.
SASE Deployment Process
The deployment of SASE is a multi-step process that requires careful planning and execution:
- Assessment: Start with an in-depth assessment of your existing network architecture and security systems.
- Define Objectives: Identify what you aim to achieve with SASE, such as improved network performance, enhanced security, or support for remote work.
- Choose a Provider: Look for a SASE provider that best meets your needs, considering factors such as global coverage, security offerings, and scalability.
- Implementation: Configure and test the SASE system. Implement it in a phased manner to avoid business disruption.
Evaluation: Regularly evaluate the system’s performance to ensure it meets the set objectives.
SASE Impact on Business
The implementation of SASE can bring about significant positive changes in businesses:
- Improved Performance: By routing traffic through the shortest path and using advanced techniques like WAN optimisation, SASE significantly enhances network performance.
- Enhanced Security: SASE provides comprehensive security features, including Secure Web Gateways (SWG), Firewall-as-a-Service (FWaaS), and Zero Trust Network Access (ZTNA), thus strengthening your network security.
- Scalability: SASE can easily scale up or down based on your needs, offering flexibility and cost-effectiveness.
- Support for Remote Work: With its location-independent design, SASE is ideal for supporting remote work, ensuring secure and efficient network access for all users.
While SASE holds immense promise, successful deployment requires learning from the experiences of others:
- Preparation is Key: Prioritise educating your IT team about SASE, assessing their skills, and ensuring they are prepared for the transition.
- Partner Selection Matters: Choose your SASE provider carefully. Ensure they can meet your specific requirements and provide robust support.
- Phased Implementation Works Best: Deploy SASE in stages rather than all at once. This approach minimises disruption and allows for issues to be addressed promptly.
- Continuous Evaluation is Crucial: Regularly monitor and evaluate your SASE system’s performance to ensure it continues to meet your evolving needs.
Navigating the path to successful SASE deployment might seem challenging, but with a clear understanding of the process, its business impact, and key lessons learned, network architects can guide their organisations towards enhanced network efficiency and security. Embrace SASE as your pathway to a more secure and efficient network.
