What is SASE (pronounced Sassy)

Secure Access Service Edge (SASE) delivers converged network and security as a service capabilities, including SD-WAN, SWG, CASB, NGFW and zero trust network access (ZTNA). SASE supports branch office, remote worker and on-premises secure access use cases. SASE is primarily delivered as a service and enables zero trust access based on the identity of the device or entity, combined with real-time context and security and compliance policies (Source)

​

Why Choose SASE

SASE allows the organizations to move beyond the traditional network perimeter and focus on securing access to resources, regardless of where they are located or how they are accessed. This is in line with the concept of Zero Trust security model, which assumes that all requests and traffic are untrusted and must be verified before they are granted access.

This approach allows for more granular and dynamic security controls that can adapt to changing network conditions and user behavior. It also enables organizations to more easily secure access to cloud-based resources and applications, which have become increasingly important with the rise of remote work and cloud migration. Additionally, SASE provides a more cost-effective and scalable solution, as it eliminates the need for multiple point solutions and allows for the centralization of security management.

​

The primary components of a SASE Architecture include:

• Software-Defined WAN (SD-WAN): SASE leverages the capabilities of SD-WAN to provide optimized network routing between SASE points of presence (PoPs).

• Firewall as a Service (FWaaS): A firewall is the foundation of any network security stack. SASE includes FWaaS to provide strong protection with minimal overhead and management.

• Zero-Trust Network Access (ZTNA): ZTNA (also called SDP) offers an alternative to legacy secure remote access solutions that embraces zero-trust policies and provides access to resources on a case-by-case basis.

• Cloud Access Security Broker (CASB): A cloud-based security solution like SASE logically needs to provide security for cloud applications. CASB is integrated into SASE to monitor and secure access to cloud-based resources.

• Data Loss Prevention (DLP): SASE leverages DLP to help protect against data loss and potential breaches by controlling the movement of data in and out of cloud applications.

• Secure Web Gateway (SWG): SWG solutions protect users against malware, phishing, and other Internet-borne threats. SASE offers SWG protection to all users, regardless of their location.

• Consolidated Management: Complex and disconnected security is one of the main challenges that SASE is designed to solve. SASE users should be able to monitor and manage all of their security solutions from a single pane of glass.

 

​​​Achieving true convergence across all of these components is essential for an organization to fully achieve the benefits of SASE.

​

Making the move to a SASE architecture does not have to be tackled all in one shot.

Let Zephon show you how to incrementally achieve SASE. 

​

​​According to Gartner:

​

​"By 2025, 80% of enterprise will have adopted a strategy to unify web, cloud services and private application access from a single vendor's security service convergence platform."
 

 
"By 2025, at least 60% of enterprises will have explicit strategies and timelines for SASE adoption encompassing user, branch and edge access, up from 10% in 2020."
