The Gartner® 2022 Strategic Roadmap for SASE Convergence report is now available from VMware. In this helpful report, the global analyst firm explains best-practice business and technical approaches for a SASE migration plan. The report lays out specific choices that security and risk management leaders can make around cloud-delivered networks and security, zero trust, SD-WAN, and SASE. It includes:
- Specific short-term and long-term recommendations for working toward a SASE architecture
- Detailed views of the current state of SASE architecture vs. the future state
- Suggestions for creating a gap analysis
- A timeline and roadmap for getting to SASE, broken into high-, medium- and lower-priority goals
The business need for SD-WAN and SASE
App and data traffic is shifting rapidly away from the old hardware-based model of office-to-data center. In the new distributed model, apps, data and the workers who use them can be located almost anywhere. However, a traditional centralized network that relies heavily on hardware must backhaul traffic through a single choke point in the data center. This slows traffic, introduces security risks, and creates poor user experiences—the opposite of what the distributed model was built to achieve.
A secure access service edge (SASE) architecture solves this problem by, at its core, shifting from a hardware-based approach to security and networking to a cloud-based approach. With SD-WAN as the primary connectivity technology, SASE brings networking and security services together in the cloud so that the distributed model can connect people and devices anywhere, at any time.
“Over the next four years, the market for SASE will grow at a CAGR of 32%, reaching almost $15 billion by 2025.”Gartner, 2022 Strategic Roadmap for SASE Convergence
Defined in 2019, SASE became an extremely popular concept in 2020 as the pandemic drove millions of employees to work from home. IT leaders soon realized that legacy digital systems were not providing the connectivity, security, or user experience needed to successfully navigate this massive change. Although SASE was not developed to address remote work, it was the right idea at the right time, and its use exploded. Now SASE architectures with SD-WAN are starting to serve multiple use cases in areas including multi-cloud, IoT, and edge compute.
Roadblocks and how to clear them
The 2022 Strategic Roadmap for SASE Convergence report also talks about obstacles to SASE adoption and both short-term and long-term ways to overcome those obstacles.
For example, many companies have not been able to see the benefits of moving to single-vendor SASE, or even dual-vendor SASE, because of existing vendor contracts and the way that enterprise buying centers have operated.
Traditionally, a networking team bought networking products, a security team bought security products, and those teams had little if any interaction. SASE is bringing these teams together over technologies such as zero-trust network access (ZTNA), which encompasses aspects of both networking and security. As SASE solutions mature, these buying and management teams will find better ways to work together. And as SASE vendors mature, it will be simpler to choose solutions with the right mix of functions for any given enterprise.
“In the 2022 Gartner CISO: Security Vendor Consolidation XDR and SASE Trends Survey, over one-third of respondents indicated they will have SASE implemented by the end of 2022, and 75% of respondents either have or will have SASE by 2024 or later.”Gartner, 2022 Strategic Roadmap for SASE Convergence
