What is SASE?
The secure access service edge (SASE), pronounced like “sassy”) is a framework identified by Gartner as a means to securely connect entities such as users, systems, and endpoint devices to applications and services that may be located anywhere. Crucially, SASE is not one technology. In its 2019 report “The Future of Network Security is in the Cloud,” Gartner defined the SASE framework as a cloud-based cybersecurity solution that offers “comprehensive WAN capabilities with comprehensive network security functions (such as SWG, CASB, FWaaS, and ZTNA) to support the dynamic secure access needs of digital enterprises.”
SASE is distinct from security service edge (SSE), which Gartner defines as a subset of SASE that only focuses on the security services needed from a SASE cloud platform.
How SASE works:
A SASE architecture combines a software-defined wide area network (SD-WAN) or other WAN with multiple security capabilities (e.g., cloud access security brokers, anti-malware), securing your network traffic as the sum of those functions.
Legacy approaches to inspection and verification, such as forwarding traffic through a multiprotocol label switching (MPLS) service to firewalls in your data center, are effective if that’s where your users are. Today, though, with so many users in remote locations, home offices, and so on, this “hairpinning”—forwarding remote user traffic to your data center, inspecting it, and then sending it back again—tends to reduce productivity and hurt the end user experience.
What makes SASE stand out from point solutions and other secure networking strategies is that it’s both secure and direct. Rather than relying on your data center security, traffic from your users’ devices is inspected at a nearby point of presence (the enforcement point) and sent to its destination from there. This means more efficient access to applications and data, making it the far better option for protecting distributed workforces and data in the cloud.
Benefits of this Technology:
- Reduce costs and complexity
- Provide centralized orchestration and real-time application optimization
- Help secure seamless access for users
- Enable more secure remote and mobile access
- Restrict access based on user, device, and application identity
- Improve security by applying consistent policy
- Increase network and security staff effectiveness with centralized management
