| Secure Access Service Edge (SASE) is a cloud architecture that delivers network and security-as-a-service functions together as a single cloud service. The acronym SASE is pronounced "sassy." Traditional network security efforts focused on the network perimeter and security policies were designed to protect the corporate network from outside threats. While this model was effective during the early days of the internet, it has become increasingly less effective in a world where a corporate network's architecture is distributed. SASE software allows organizations to view their network and security tools in a single management console, without needing to know where network components, endpoints or end users are physically located. To keep the data secure, SASE uses a zero-trust security model. Instead of sending traffic back to the data center to be inspected, SASE clients send traffic to a point of presence (PoP) for inspection before traffic can be forwarded to the internet or to other SASE clients. Essentially, the SASE architecture seeks to redefine the role of the private data center by making it a "virtual private data center." No longer the sole guardian of corporate information, the physical data center becomes just one of several locations to store data across the wide area network (WAN).
With the number of remote workers increasing, and organizations increasingly using cloud services to run applications, SASE offers a convenient, agile, cost-effective and scalable SaaS product for networking and security. Continue reading about SASE...
