Secure Access Service Edge (SASE)

Secure Access Service Edge is a unified technology to protect Web, cloud and private app usage.

What is SASE?

Secure Access Service Edge (SASE) is a new category of enterprise networks introduced by Gartner. SASE converges SD-WAN and several network security solutions (FWaaS, CASB, SWG and ZTNA) into a unified cloud-native service.

Until now, network access was implemented with complex and expensive solutions, managed as silos. However, this has made IT less agile.

With SASE, companies can reduce the time it takes to develop new products, deploy them to market and respond quickly to changes in the competitive business landscape. 


What does it mean to adopt a SASE solution?

The shift to smart working and the emergence of a cloud-centric culture are having a major impact on enterprise networks and informationsecurity. Network models have changed, and companies must implement new services and meet new requirements quickly. 

A SASE schedule provides the agility and flexibility needed in this new environment. SASE allows new branches to be deployed remotely with reduced overhead. It also provides the security stack to ensure that employees and contractors can access systems securely from anywhere.

As a result, Gartner predicts that 20 percent of companies will soon be using SWG, ZTNA and FWaas from the same vendor (more on SASE components below). By 2024, at least 40 percent of companies are expected to have an official SASE adoption strategy.

What are the benefits of SASE?

Improves agility

With SASE, it is easy to deploy new resources. All that is needed is to provide a perimeter client and connect it to the SASE platform. There is no need to maintain local infrastructure.

Improves safety through unified criteria

SASE provides a complete security stack, protecting all resources with a unified security policy. It provides complete visibility into WAN and Internet traffic without blind spots.

Simplification of the network stack

SASE provides a simpler network and security stack by consolidating multiple solutions. It reduces initial costs and eliminates the need for in-house management.

How does SASE work?

SASE provides a single cloud-based network that connects and protects any physical, cloud, or mobile enterprise resource anywhere. A SASE schedule has four main features:

Identity guide

Users' identities and resources determine the level of access, network experience, and quality of service for each network connection, based on a unified organizational policy.

Cloud Native

SASE is elastic, self-healing, and self-sufficient. Its nature enables it to adapt quickly to business needs and make network services available from anywhere.

Support for all margins

SASE can equally serve any edge, including on-premise data centers, branch offices, cloud resources and mobile users on the go.

Global distribution

SASE operates on a global scale to provide full network and security capabilities with a high-performance, low-latency experience for all locations.

What does SASE consist of?

Software-defined WAN (SD-WAN)

SD-WAN enables optimal WAN management. SASE leverages SD-WAN capabilities in order to provide optimized network routing, global connectivity, WAN and Internet security, cloud acceleration, and remote access.

Firewall as a Service (Fwaas)

A firewall is the foundation of any network security stack. SASE includes FWaaS to provide the scalability and elasticity needed for digital business and to extend a complete network security stack wherever it is needed.

Zero Trust Network Access (ZTNA).

ZTNA offers a modern approach to protecting application access for users. It embraces a zero-trust policy, in which application access is dynamically adjusted based on user identity, location, device type, and more.

Unified Management

SASE solves the complexity of managing heterogeneous products. A true SASE allows users to monitor and manage all network and security solutions from a single control panel.

Cloud Access Security Broker (CASB)

CASB helps companies adapt to new threats arising from cloud computing. When provided as part of a SASE service, the complexity of integration with CASB itself is obviously eliminated.

Secure Web Gateway (SWG)

SWG solutions protect users from malware, phishing, and other Web-borne threats. SASE offers SWG protection to all users, everywhere, and eliminates the need to maintain policies across multiple platforms.

With Cato Networks, we have integrated together SD-WAN capabilities, a backbone and a security service for our sites and mobile users, at a much lower cost.

What problems can you solve with SASE?

Networking and security solutions are too complex to manage and expensive to own

Current network and security solutions such as remote VPN access are incompatible with cloud-centric, mobile-first digital business. Networking is rigid and static, and security is fragmented across multiple domains. Together, networking and security are slowing down business instead of enabling innovation and agility.

Cloud-native convergence of network and security enables simplicity, agility and lower costs

Cato Networks provides the world's first SASE platform(and has been recognized by Gartner as a "Sample Vendor" in the SASE category of the "Hype Cycle for Enterprise Networking, 2019″) through a globally distributed cloud service that provides enterprise network and security capabilities at all edges.



Service Agility


Slow and complicated

IT teams must configure different solutions across multiple consoles while maintaining consistency and control of the infrastructure. Provisioning new resources is slow and depends on complex multi-product integrations.

Cato SASE Cloud

Quick and easy

Cato Networks enables IT teams to deliver optimized networks and powerful security to all sites, applications, and users regardless of location. Provisioning new resources is quick and easy with Cato's full range of optimization and security features immediately available.



Visibility and Control

The dreaded Silos

Technical silos created by the most effective solutions limit collaboration among teams. Lack of visibility and fragmented control lead to slower problem resolution, decreased security with relative dissatisfaction on the part of the business. 

Teamwork rediscovered

IT teams leverage Cato's converged software stack to maximize visibility into network traffic and security events. From the same interface, IT professionals configure and enforce corporate policies across the enterprise. This enables better collaboration among teams, improving overall service delivery to the business. 



Infrastructure Management

Intense workload

Owning and managing multiple on-premise networking and security solutions forces IT teams to spend a lot of time on day-to-day management, scaling and upgrading. This leaves less time to complete projects for the business.

Focus on Business

With Cato Networks, IT teams are relieved of the hard work of infrastructure maintenance. Cato Networks ensures that up-to-date service is ready to optimize and protect all customer network traffic everywhere. This allows IT to focus valuable resources and expertise on company-specific requirements.




Visibility and Control

Complexity costs

Purchasing, integrating, and maintaining multiple products is expensive. Each product must be organized to support current needs and future growth and often requires upgrades as requirements change. As the number of products increases, complexity increases exponentially. In addition, transferring complexity to service providers only increases their costs, leading companies to pay more or suffer the loss of service quality.

Simplicity costs less

Cato Networks greatly simplifies the delivery of networking and security to the enterprise. The required functionality is built-in, undefined, and there is no need to size, scale, or maintain the Cato Networks service. Cato's cloud-based platform and flexible management options enable significant cost reductions.

SASE value for WAN transformation

Digital change and WAN transformation does not happen overnight. In fact, this is often composed of multiple projects involving SD-WAN, Internet security, cloud migration, mobile access and more.

As you consider your next incremental investment in your network (SD-WAN, a global connectivity solution, or a security solution), ask yourself whether the right decision is to choose a solution that meets the needs of the current project or a strategic SASE platform that can meet the requirements of current and future projects.

SASE is used to deliver converged enterprise networks and security services from a globally distributed cloud service. SASE overcomes the cost, complexity, and inflexibility of loosely integrated, geographically constrained solutions. When combined with a global private exchange, SASE can also address the challenges of WAN and cloud connectivity.

Solutions such as SD-WAN, NGFW, SWG, and VPN meet specific network and security requirements. The need to purchase, size, scale and maintain each solution separately makes the IT infrastructure complex and expensive. SASE is an alternative to those technology silos. It provides a globally distributed cloud service that replaces the physical and virtual solution with a cost-effective, scalable and agile alternative.

SD-WAN is a key component of the SASE platform that connects branch offices and data centers to the SASE cloud service. SASE extends SD-WAN to address the entire WAN transformation journey that includes security, cloud, and mobility on a global scale.

SASE is important because the convergence of network and security in a cloud-native service enables IT teams to connect and secure all corporate locations and users in an agile, cost-effective and scalable way.

As a result of the shift to the cloud and the increase in the mobile workforce, solutions can provide only the functionality the business needs at increasing complexity and cost. SASE's converged, cloud-native, globally distributed organization easily delivers the functionality the business needs to all users. SASE thus overcomes the cost, complexity and high overhead of running many legacy solutions.

SD-WAN is only the first step in the WAN transformation journey. It lacks key security functions , global connectivity capabilities, and support for cloud resources and mobile users. A comprehensive SASE platform can support the entire WAN transformation journey, as it enables IT to provide the network and security functions needed by the business in an agile and cost-effective manner.

SASE is end-to-end protected. All communications through the SASE platform are encrypted. Threat prevention capabilities, including decryption, firewall, URL filtering, anti-malware and IPS, are natively integrated into SASE and are available globally for all connected edge devices.

SASE is an identity-based service with an integrated, globally distributed cloud that supports all margins. Alternative architectures, such as service chaining appliances, hosting appliances and virtual machines, and telecommunications bundles, are based on solutions and not on a converged software stack designed for the cloud.
