At Guardian Telecom Advisors, we understand the evolving landscape of enterprise networking and security. As companies increasingly adopt cloud-first strategies, traditional networking solutions like MPLS (Multiprotocol Label Switching) are becoming less viable. In this blog, we explore Secure Access Service Edge (SASE), its benefits, the right time to consider migrating, key concerns, and how to navigate this transition seamlessly.
What is SASE?
Secure Access Service Edge (SASE) is a transformative architecture that integrates networking and network security functions. It builds on established technologies like cloud-based security, SD-WAN (Software-Defined Wide Area Network), and zero-trust access. By converging these technologies, SASE offers immediate and long-term benefits, including enhanced protection, improved user experience, agility, and increased productivity for IT teams and business users. A mature SASE solution can be delivered as a turnkey as-a-service subscription or as individual components tailored to your specific needs.
When is it Time to Consider Migrating to SASE?
MPLS has been a reliable networking solution for over two decades. However, in today's cloud-centric world, its limitations are becoming more apparent. According to a 2023 survey of CIOs, CISOs, and IT leaders, 62% plan to eliminate MPLS, with only 7% intending to invest further in it. The clear trend towards SASE and other modern solutions indicates that now is the time to consider migrating, especially if you are experiencing performance issues, facing increased security risks, seeking greater flexibility, or desiring cost efficiency.
Performance Issues
MPLS may no longer meet the performance demands of cloud applications and remote workforces. As more businesses move to cloud-based applications and services, the need for a network that can handle high traffic volumes with low latency becomes critical.
Increased Security Risks
Traditional MPLS might be inadequate in addressing today's sophisticated security threats. SASE offers robust security measures to safeguard data and applications, making it a more suitable choice for modern enterprises.
Greater Flexibility
Modern businesses need scalable and agile networking solutions to keep pace with digital transformation. SASE provides the flexibility to quickly adapt to new opportunities and challenges.
Cost Efficiency
SASE can offer a more cost-effective alternative by reducing the need for expensive hardware and maintenance. By consolidating networking and security functions, enterprises can achieve significant cost savings.
Key Concerns with Migrating to SASE
Migrating to a new network architecture can be daunting, and enterprises often hesitate due to perceived risks. Common concerns include the belief that MPLS is the only way to attain guaranteed performance and reliable security, the time and expertise required for migration, and the fear of unexpected surprises or outages during a large-scale migration. However, with the right approach, these risks can be mitigated and avoided.
Guaranteed Performance and Security
There is a belief that MPLS is the only way to attain guaranteed performance and reliable security. However, modern SASE solutions provide similar, if not better, performance and security through advanced technologies like secure SD-WAN and cloud-based security services.
Internal Resources
Migration requires time and expertise, which are often in short supply. Partnering with experienced advisors like Guardian Telecom Advisors can help you navigate the complexities of migration and ensure a smooth transition.
Migration Complexity
The fear of unexpected surprises or outages during a large-scale migration can be a significant deterrent. However, with a well-defined migration plan and the right tools, these risks can be effectively managed.
Navigating the Current Landscape: Tips for a Smooth SASE Migration
Successfully migrating to SASE involves careful planning and leveraging the right tools and expertise. Here are some strategies to ensure a smooth transition:
Choose the Right Tools
Managed SASE solutions and secure SD-WAN provide flexibility and visibility to optimize the routing of critical and latency-sensitive applications. Software-defined networks (SDN) make scaling or descoping transport simpler compared to MPLS. Platforms that offer a holistic view of network performance across the first, middle, and last miles of connectivity are essential. Ensure your solution reduces complexity and offers easy correlation between network and security events. Modern IT teams need cloud-like reporting and visibility available 24x7.
Define a Comprehensive Migration Strategy
Creating a project plan is crucial. Perform migrations in stages, considering all impacted teams and workflows. Clearly define who, how, and when stakeholders will be notified of key events. Update policies for new partners, tools, or processes. Outline hardware staging needs and circuits that require provisioning or deprovisioning. Use migration as an opportunity to update and create new documentation across the enterprise. Update incident response plans to accommodate new partners and vendors.
Build a Winning Team of Experts
Assign a dedicated project team to ensure seamless execution with a project manager, network architect, and 24/7 Network Operations Center (NOC). Agree on strict service level agreements (SLAs) to cover the performance of the first, middle, and last mile of service, and service-related items like tickets, maintenance, and incident response. Ensure that all knowledge is shared and documented in a central repository.
