SASE Benefits For Your Enterprise In 2022

SASE comprises a technologies package that integrates security features into the global network fabric so that it is always available regardless of user location, application, or the resource that is being accessed.

Security demands for enterprise networks have heightened since the advent of Coronavirus pandemic which necessitated remote work systems in most organizations. SASE has shown to offer lots of solutions to keep the network safe.

SASE Explained

SASE meaning security access service edge is a cloud-based technique that functions by incorporating security and network capabilities in a unified framework. It uses an inspection engine to analyze traffic at an edge point of presence before it is forwarded or routed.

It gives access to on-premises resources and cloud-based services via a centralized approach. This is done by combining network security and access controls via a unique management control. This allows firms to have absolute visibility into network and application performance and take p; prompt steps to avoid attacks.

A SASE solution also classifies traffic and restricts unauthorized applications or content access. It also assures a proactive security posture by allowing organizations to create a unique identity and access based on security policy conditions in place of fixed policies that were fixed on perimeters.

It ensures enhanced security as access is granted only to certain applications required by users in line with their work profiles. It also ensures that the user is authenticated and authorized using the multi-factor authentication that allows users access to all applications with a single set of credentials. With DNS as the security control point, it is easier to detect and stop cyberattacks on time.

Components Of A SASE model

SASE can be divided into six main elements in terms of its technologies and capabilities:

Software-Defined Wide Area Network (SD-WAN)

Software-defined wide area network (SD-WAN) is an overlay architecture that minimizes complexity and maximizes the user’s experience by choosing the perfect route for traffic to cloud apps, data centers, and the internet. It also permits the rapid deployment of new services and apps and helps you control policies across many locations.

Secure Web Gateway (SWG)

A secure web gateway prevents unsecured internet traffic from accessing your internal network. It protects users and employees from being victims of vulnerable websites, malware, malicious web traffic, internet-borne viruses, and other cyber threats.

Cloud Access Security (CASB)

Cloud access security (CASB) broker prevent lack of visibility, data leaks, regulatory noncompliance, and malware infection by ensuring the safe use of cloud apps and services. Cloud apps hosted in private clouds, public clouds, or delivered as SaaS (software-as-a-service) are secured.

Firewall as a Service (FWaaS)

Firewall as a service (FWaaS) allows you to replace physical firewall appliances with cloud firewalls that supply advanced Layer 7/next-generation firewall capabilities, along with access controls, like DNS security, advanced threat prevention,

URL filtering and intrusion prevention systems (IPS).

Zero Trust Network Access (ZTNA)

Zero trust network access allows remote users access to internal apps based on granular policies. In addition, remote users can secure connectivity, exposing your apps to the internet.

Why Choose SASE For Your Enterprise?

Here are some reasons you should consider Security Access Service Edge for your business.

Cost Reduction

With SASE, enterprises exclude several vendors’ irregular models of virtual appliances and leverage a unique cloud-native solution. 

Enterprises can deliver more technologies and services through a single provider instead of two or more, removing the cost of miscellaneous appliances and minimizing the cost related to unneeded network complexity. For instance, SASE simplifies ongoing patches, upgrades, and network maintenance, further reducing cost.

Also, reducing network complexity implies a reduction in the workload for IT staff and which automatically reduces the IT staffing costs.

WAN Scalability

SASE offers to WAN architecture what AWS, Digital Ocean, and Azure did for application delivery. It activated elasticity and hyper-scalability within the WAN infrastructure.  

With SASE, IT can access a site online within minutes instead of weeks as it is with a traditional WAN. Also, less physical hardware equals less maintenance downtime and reduced additional software licenses. With these improved efficiencies, IT can delegate higher priority tasks to staff like security and network monitoring.

Ease Of Management

One of the major SASE benefits is the ease of management. This is so because SASE management is a central cloud-based management application that manages the entire service from a single point.

For example, Managing SD-WAN, SWG, NGFW, and VPN devices across many office locations in an enterprise network requires increased IT labor as more sites are included.

However, Security Access Service Edge management complexity doesn’t move along with the network growth because it’s a single cloud-based management application. Hence it controls the whole service so that the IT team doesn’t need to spend time with overwhelming maintenance tasks like hardware replacement and patches.

Edge To Edge Security

SASE is designed to connect and secure the enterprise WAN in a simple way that enhances performance. Since SD-WAN is a major part of the SASE solution, features like WAN optimizations and an active-active failover improves network resilience and increases performance.

Being a part of a whole network security stack, a SASE solution includes functionality such as IPS, NGFW, SWG, and next-generation network architecture; therefore, the cloud-native model shields all the edges to attain proper network visibility.

Conclusion

The Security Access Service Edge activities can not be overemphasized; however, to crown it all, SASE is known to provide constant network monitoring that shows the performance of data flow, which includes remote data streams that are distributed across virtualized data centers and cloud environments.
