What is SASE? Protecting Your Business Network With SASE
The Future of Network Security in the Cloud
With an increase in remote users and software-as-a-service (SaaS) applications, data moving from the data center to cloud services, and more traffic going to public cloud services and branch offices than back to the data center, the need for a new approach for network security has risen.
Existing network approaches and technologies simply no longer provide the levels of security and access control digital organizations need. These organizations demand immediate, uninterrupted access for their users, no matter where they are located. With an increase in remote users and software-as-a-service (SaaS) applications, data moving from the data center to cloud services, and more traffic going to public cloud services and branch offices than back to the data center, the need for a new approach for network security has risen.
What is SASE?
Secure Access Service Edge (SASE) is the convergence of wide area networking, or WAN, and network security services like CASB, FWaaS and Zero Trust, into a single, cloud-delivered service model. SASE makes it possible for identities of entities to be associated with people, groups of people (branch offices), devices, applications, services, IoT systems or edge computing locations. SASE converges SD-WAN and Security Service Edge (SSE) functions, including FWaaS, CASB, DLP, SWG, and ZTNA, into a unified, cloud-native service.
1. Identity-driven
User and resource identities determine the level of access, networking experience, and quality of service for every network connection, based on a unified organizational policy.
2. Cloud-native
SASE is elastic, self-healing, and self-maintaining. Its cloud native nature allows it to rapidly adapt to business needs and make network services available from any location.
3. Support for all edges
SASE can equally service any edge including on-premise data centers, branch offices, cloud resources, and mobile users on the go.
4. Globally distributed
SASE operates on a global scale to deliver all networking and security capabilities with high performance and low latency experience for all edges.
SASE benefits for your business
SASE eliminates the effort and costs required to maintain complex and fragmented infrastructure made of point solutions, reduces the risk for breach and data loss with optimal security posture, enables secure work from anywhere and improves access to global applications on premises and in the cloud.
Performance Benefits
1. Instant connectivity
The SASE architecture leverages key cloud capabilities including elasticity and scalability. This provides a platform that instantly adapts to emerging business needs, such as connecting a remote workforce with just a click of a button; or provisioning new resources easily for quick global expansion.
2. Single-pass processing
True SASE implements a single-pass engine that processes each packet for multiple networking and security objectives in parallel. This delivers maximum flexibility with minimal latency and resource requirements.
3. Global availability
SASE’s globally distributed PoPs ensure that all networking and security capabilities are available everywhere, delivering the best possible experience to all edges.
4. Simple management
Managing an ever-growing pile of point solutions is becoming too complex, too slow. One of the SASE benefits is that, management becomes simple via a single-pane-of-glass that provides control across an entire enterprise.
5. No maintenance
IT is relieved of maintenance tasks like patching and hardware replacements, and can focus efforts on responding quickly to evolving business challenges.
Security Benefits
1. Same security everywhere
Legacy appliances often lack critical functions such as IPS, NGFW, and SWG. SASE solves this problem with a full security stack built into its underlying network infrastructure, with all edges enjoying the same level of protection from a unified policy.
2. Identity based
User and resource identity, as opposed to just an IP address, drives SASE policies. This approach reduces operational overhead by letting enterprises develop one set of networking and security policies for users regardless of device or location.
3. No capacity limitations
A cloud-native service, SASE removes all appliance capacity concerns, enabling IT to fully protect all resources and maintain an optimal security posture.
4. Self-healing platform
A SASE platform can recover from failures at all levels of its architecture, ensuring an always-on service for maximum uptime.
5. Full visibility
With SASE, IT has complete visibility into the network as all WAN and Internet traffic passes through the SASE Cloud. There are no blind spots and IT is able to easily maintain control of the entire network.
Costs Benefits
1. Quick ROI
SASE enables augmenting or replacing MPLS altogether. This offers an immediate, significant cost-saving compared to the expensive MPLS links.
2. Optimized cost model
SASE eliminates the need for any CAPEX purchases and in-house management and maintenance. All costs are transformed to OPEX.

Get Unbeatable Cybersecurity Without Breaking The Bank
Achieving excellence in cybersecurity doesn’t mean you have to hire and invest large amounts in resources, skills, and software tools. In fact, most businesses already have security tools included in their license packages, but struggle with scarcity in resources, expertise, and therefore don't make the prioritization of cybersecurity over other more “pressing” business needs.

Hybrid Network Architecture - Security For Your Cloud & On-site Data Center
Often businesses are running servers that host custom applications like email servers, custom applications etc., and will therefore need a hybrid network security solution. In such cases you will need both a SASE and SD-WAN network security solution, also known as hybrid network security.
