Figure 3: SASE – End to end landscape view
Currently, the SASE market is a crowded space with various technologies and vendors bringing their own points of view. In the near future, great convergence and consolidation is expected. Here are the three types of solution providers and their focus areas:
- Connectivity centric solution providers: Most traditional networking vendors, like Cisco and VMware, are expanding their product portfolios to the edge to improve user experiences and to optimize wide area network (WAN) connectivity.
- Security centric solution providers: Vendors in this category of offerings primarily focus on the security aspects by customizing technology solutions. Some of the key players in this segment are Akamai Technologies, Palo Alto Networks, etc. and these are sometimes bundled along with SDWAN offerings.
- Compliance solution providers: While it is important to have secure connections, it’s equally crucial to have control over the data that is being accessed, which is why compliance and governance are essential across industries. Some of the players in this segment focus on identity management (IDAM) and compliance solutions that include, but are not limited to antivirus, data protection, and data loss prevention. Some of the players in this segment are Zscaler, McAfee Antivirus, Cisco virtual private network (VPN), Microsoft multifactor authentication (MFA), etc.
Some of the vendors providing SASE technologies as a whole, in addition to the major players mentioned earlier are Versa Networks, Cato Networks, Fortinet, Aruba, Cloudflare, Perimeter 81. The vendors in this category are emerging technology companies that can offer differentiated value propositions.
- For flexible, cost effective scalable bandwidth, approximately 30% of companies will use only internet WAN connectivity by 2023, compared with approximately 15% in 2020.
- From less than 5% in 2020, 30% of enterprises will adopt cloud delivered standard wire gauge (SWG), cloud access security broker (CASB), zero trust network access (ZTNA), and branch office firewall as a service (FWaaS) capabilities from the same vendor by 2024.
- By 2025, at least 60% of enterprises will have explicit strategies and timelines for SASE adoption encompassing user, branch, and edge access, up from 10% in 2020.
SASE adoption models1
As SASE evolves as a model and framework, and the transformation models require time to mature, the existing models have some advantages before becoming full-fledged matured models. Key approaches for SASE adoption include process, people, measurement, technologies, and strategy. The strategy will be a combination of short, medium, and long term.
