The Convergence of Networking and Security: An Introduction to SASE

The Problem with Silos

For many years, networking and security have been treated as two separate disciplines. This has led to a number of problems, including:

Complexity: Managing separate networking and security solutions can be complex and time-consuming.
Inconsistency: It can be difficult to maintain consistent policies across separate networking and security solutions.
Lack of visibility: It can be difficult to get a complete view of the network when networking and security are managed in separate silos.

What is SASE?

Secure Access Service Edge (SASE) is a new approach to networking and security that combines them into a single, cloud-delivered service. SASE is designed to provide a more simple, agile, and secure way to connect users to the applications and data they need.

Key Components of SASE

SASE is made up of a number of key components, including:

SD-WAN: SASE uses SD-WAN to provide a more flexible and agile way to connect branch offices to the cloud.
Firewall as a Service (FWaaS): SASE uses FWaaS to provide a centralized firewall that can be used to protect the entire network.
Zero Trust Network Access (ZTNA): SASE uses ZTNA to provide secure access to applications and data for remote users.
Cloud Access Security Broker (CASB): SASE uses CASB to provide visibility and control over cloud applications.

Benefits of SASE

SASE can provide a number of benefits, including:

Reduced Complexity: SASE can help to reduce the complexity of networking and security by combining them into a single, cloud-delivered service.
Increased Agility: SASE can help organizations to be more agile by allowing them to quickly and easily provision new networking and security services.
Improved Security: SASE can help to improve security by providing a single, unified way to manage security across the entire organization.
Reduced Costs: SASE can help to reduce costs by eliminating the need to purchase and manage separate networking and security solutions.

Conclusion

SASE is a new and innovative way to deliver networking and security services. It offers a number of benefits over the traditional approach, including reduced complexity, increased agility, and improved security. As organizations continue to embrace the cloud, SASE is likely to become an increasingly popular option for delivering networking and security services.
