SASE (Security as a Service) delivers an integrated network and security platform that connects users, offices, and data centers securely. This unified, cloud-native architecture helps organizations adapt to the growing need for remote workers and mobile applications.

Using identity as the core context, SASE dynamically applies security services and policies to each WAN session. It ensures all connections are inspected and secured regardless of location, app, or encryption.

SD-WAN

Unlike traditional WAN solutions like MPLS, which require a significant investment in hardware, SD-WAN decouples the network control and management functions from the networking hardware. It makes deploying, scaling, and operating easier and can help reduce costs.

Moreover, the centralized control and policy application can accommodate fluctuations in traffic, allowing for a reliable user experience. It benefits digital enterprises that want to optimize and scale their networks in line with their growth, technology upgrades, and business goals.

SASE, or Secure Access Service Edge, is a cloud-native network architecture that combines software-defined wide-area networking (SD-WAN) with security functionality in a single solution. It promises to simplify WAN deployments, improve efficiency and security, and provide application-specific bandwidth policies.

SASE uses intelligent routing to connect remote and branch users directly to cloud services and improve end-user application performance to achieve this. It also includes features such as CASB, FWaaS, and ZTNA, which combine to deliver a comprehensive security solution for enterprise WANs.

The main benefit of SASE is that it brings consistent security policy enforcement across the entire network and provides remote monitoring, inspection, and auditing. It also eliminates the need for a separate security architecture at every branch office or data center. It saves organizations time and money while ensuring their WAN infrastructure stays updated with changing security regulations and threats.

CAST

SASE components combine SD-WAN technology with network security functionality into a single cloud-native solution. It enables enterprises to connect remote and branch users directly to cloud services and improves end-user network and application performance.

SASE addresses a significant challenge facing digital organizations today: how to keep up with the growth of SaaS applications, shadow IT, data growth, and the growing number of dispersed and remote employees. In these challenges, many enterprises need a next-generation CASB in their SASE architecture to protect cloud services and ensure employee safety.

CASBs offer visibility into cloud content, compliance with data policies, cloud security, and protection from malware, phishing, and other cyber threats. They also provide vital data privacy controls and help IT ensure compliance with data residency laws.

One key benefit of a CASB is that it can be used to inspect and analyze data from all cloud environments, including public, private, and hybrid clouds. This ability provides deep security that follows data from when it leaves the organization’s data center to its final destination in the cloud.

CASBs can assess configuration risk for IaaS, PaaS, and SaaS services. This assessment can help protect a company’s sensitive data, even if the service is misconfigured. It can also help prevent data breaches by providing additional insurance against misconfigurations.

FWaaS

FWaaS is a cloud-based firewall that offers advanced security capabilities without the need to deploy and manage firewall appliances. FWaaS also gives IT departments complete network visibility and control over all internet traffic, no matter where it originates or ends.

Using deep packet inspection, FWaaS can detect threats hidden inside data packets. This technology allows FWaaS to recognize and block suspicious traffic before it can damage your network.

In addition to FWaaS, SASE also uses cloud-access security brokers (CASB), zero-trust network access (ZTNA), cloud-secure web gateways (CSWG), and other security technologies as core abilities. SASE also combines these core capabilities to deliver a range of threat detection functions independent of location.

SASE’s global fabric of PoPs delivers a complete set of WAN and security capabilities with low latency wherever business offices, cloud applications, or mobile users are located. SASE providers must have extensive peering relationships with each other and their customers to provide low latency.

Moreover, SASE provides a flexible and scalable approach to cloud adoption that allows organizations to scale their networks up or down as needed. It reduces the cost of OpEx consumption and makes it easier to adjust to the needs of new employees or incoming applications.

ZTNA

SASE is a security framework that unites several critical network security services and networking capabilities in one unified model. It reduces the cost of deploying, managing, and maintaining multiple solutions for securing enterprise data and applications, which can increase the productivity of IT teams and improve user experiences.

SASE’s core abilities include SD-WAN, SWG, CASB, and FWaaS. It is cloud-delivered and scalable as your organization grows, enabling accelerating digital transformation and freeing IT team members from repetitive tasks.

The foundation for a SASE solution is an identity management platform that provides secure access to applications and data through a robust digital identity, regardless of device or location. It minimizes the danger of unauthorized users or malicious actors by ensuring that only authorized users and devices can access business resources.

Zero Trust Network Access (ZTNA) is a security architecture that relies on identity-based access control and the principle of least privilege, limiting access to only those applications or devices that need it. It eliminates the risk of lateral movement and enables employees to work from anywhere, anytime, without fear of being compromised or accessing confidential information.

ZTNA connects users to applications via a cloud-based connector installed in the same network as the application. The service authenticates the user and validates the application before granting access. It reduces the need for a separate agent on the user’s device and helps businesses provide secure connectivity to employees using BYOD or unmanaged devices.
