SASE Solutions for Business

Secure Access Service Edge (SASE) is a cloud architecture model that combines multiple network and security functions and delivers them as a single, unified cloud service. This enables organizations to easily and effectively secure their entire network infrastructure—no matter where network components are located—using one set of networking and security policies.

 

What is SASE?

SASE is a security framework that converges software-defined wide area networking (SD-WAN) and Zero Trust security solutions into a converged cloud-delivered platform that securely connects users, systems, endpoints, and remote networks to apps and resources. SASE has four main traits:

- Identity-driven: Access is granted based on the identity of users and devices.
- Cloud-native: Both infrastructure and security solutions are cloud-delivered.
- Supports all edges: Every physical, digital, and logical edge is protected.
- Globally distributed: Users are secured no matter where they work.

The main goal of SASE architecture is to provide a seamless user experience, optimized connectivity, and comprehensive security in a way that supports the dynamic secure access needs of digital enterprises. Instead of backhauling traffic to traditional datacenters or private networks for security inspections, SASE enables devices and remote systems to seamlessly access apps and resources wherever they are—and at any time.

 

Why SASE?

SASE offers many benefits for businesses that have embraced a remote or hybrid work model, BYOD, and/or the use of third-party cloud applications. Some of the advantages of SASE are:

- Reduced complexity: SASE simplifies the management and deployment of network and security solutions by consolidating them into a single cloud service that can be easily configured and updated.
- Improved performance: SASE optimizes the network performance and user experience by routing traffic through the nearest cloud edge point, reducing latency and bandwidth consumption.
- Enhanced security: SASE provides consistent and granular security policies that can be applied to all network components, regardless of their location or device type. SASE also leverages Zero Trust principles to verify every request and prevent unauthorized access to sensitive data and applications.
- Lower costs: SASE reduces the operational and capital expenses associated with maintaining multiple network and security solutions, hardware, and licenses. SASE also enables businesses to scale up or down their network and security needs as per their demand, without compromising on quality or efficiency.

How SASE Works?

SASE can be broken down into six essential elements:

- Software-defined wide area network (SD-WAN): A software-defined wide area network is an overlay architecture that uses routing or switching software to create virtual connections between endpoints —both physical and logical. SD-WANs provide near-unlimited paths for user traffic, which optimizes the user experience, and allows for powerful flexibility in encryption and policy management.
- Firewall as a service (FWaaS): Firewall as a service moves firewall protection to the cloud instead of the traditional network perimeter. This enables organizations to securely connect a remote, mobile workforce to the corporate network, while still enforcing consistent security policies that reach beyond the organization’s geographic footprint.
- Secure web gateway (SWG): A secure web gateway is a web security service that filters unauthorized traffic from accessing a particular network. The goal of a SWG is to zero in on threats before they penetrate a virtual perimeter. A SWG accomplishes this by combining technologies like malicious code detection, malware elimination, and URL filtering.
- Cloud access security broker (CASB): A cloud access security broker is a security solution that monitors and controls the use of cloud applications and services by users and devices. A CASB provides visibility into cloud activity, enforces data security and compliance policies, and protects against data breaches and insider threats.
- Zero Trust Network Access (ZTNA): Zero Trust Network Access is a set of consolidated, cloud-based technologies that operates on a framework in which trust is never implicit and access is granted on a need-to-know, least-privileged basis across all users, devices, and applications. In this model, all users must be authenticated, authorized, and continuously validated before being granted access to company private applications and data. ZTNA eliminates the poor user experience, operational complexities, costs, and risk of a traditional VPN.
- Additional security tools: Some SASE providers also bundle additional security tools into their SASE solutions, such as email security, DNS filtering, or threat intelligence. These tools provide extra layers of protection and visibility for the network and its users.

SASE delivers all of these functionalities as a single service at the network edge, as opposed to the traditional method of delivering it to the data center. This enables organizations using a SASE solution to deliver universal, consolidated security and connectivity to all of their endpoints, applications, and users.

Choosing Kylada SASE Solutions:

There are many SASE solutions available in the market, each with its own features, capabilities, and pricing. To choose the best SASE solution for your business, you should consider the following factors:
