Secure Access Service Edge (SASE) is a network architecture that combines software-defined wide area networking (SD-WAN ) and security functionality into a unified cloud service that promises simplified WAN deployments, improved efficiency and security, and application-specific bandwidth policies. billion by 2025. What is SASE?
In a bid to replace MPLS circuits and SD-WAN appliances, Cloudflare has introduced Magic WAN and Magic Firewall and partnerships with VMware, Aruba, Digital Realty, CoreSite and EdgeConneX.
In response to these realities, Gartner coined a new term, secure service edge (SSE), which is essentially SASE minus SD-WAN , the network access part of the equation. As previously noted, SASE adds SD-WAN. Palo Alto has a strong ZTNA offering, and it can provide SD-WAN for organizations that want to take the single-vendor SASE route.
SASE vs. SD-WAN SSE can be considered a subset of SASE (secure access service edge), which is a term coined by Gartner to describe a cloud-based service that combines networking and security to give remote workers safe access to internet-based resources. SSE is essentially SASE minus SD-WAN, the network access part of the equation.
Greg Ferro examines a potential SDN use case (an OpenFlow use case) in the form of enterprise firewall migrations. He follows that post up with a post examining PCoIP on WAN connections , where he provides some good information on PCoIP and VPNs, WAN accelerators, and protocol tuning. OVS on VirtualBox? Why yes, I think I will.
Monitoring of LAN, WAN, VPN, and distributed sites. Monitoring of virtual servers. SLA monitoring (service level agreement). Monitoring QoS (Quality of service, for example, to monitor VoIP). Environmental monitoring. Extensive event logging. IPv6 support. Monitoring without agents. Flexible Alerts. Various user interfaces. Detailed reports.
And then theres Broadcom, which has traditionally been known as a chip maker, but has the potential to offer a full-stack solution to enterprise customers based on its hardware offerings (GPUs, network adapters, controllers and switches) and software from its acquisitions of CA, Symantec and VMware.
