Secure Access Service Edge (SASE)

service overview

What is SASE?

Secure Access Service Edge (SASE) is an enterprise networking technology category that combines the capabilities of network and security point solutions into a unified, global cloud-native service. It is an architectural transformation of enterprise networking and security that enables IT to provide a holistic, agile and adaptable service to the digital business. What makes SASE unique is its transformational impact across multiple IT domains.

Tackling emerging challenges with point solutions can lead to technical issues that are complex and costly to manage. This ultimately slows down IT and its adaptability to these business requirements. SASE offers a new networking and security platform that is identity-driven, cloud-based, distributed worldwide and connects all network edges securely.

SASE is the amalgamation of networking and security that enhances access performance, reduces complexity, and bolsters your security posture on a massive scale. Our SASE solution is built on a cloud-based architecture, is distributed globally across many Points of Presence (PoPs); and supports all edges of your network. Including locations, applications, clouds and users.

With SASE, enterprises can bolster their security, and respond to changes in operational, business conditions or the competitive environment.

The challenge.

Point solutions for networking and security are too convoluted to manage and costly to own. Current networking and security solutions are incompatible with the cloud-centric and mobile-first digital business. The network is rigid and static, and security is heavily fragmented across multiple domains. Together, networking and security are slowing down the business instead of enabling innovation and agility.

The SubRosa solution.

Cloud-native Convergence of Networking and Security enables Simplicity, Agility, and Lower Costs. Through a globally distributed cloud service that provides enterprise network and security capabilities to all edges.


SASE value for WAN transformation.

Transformation and the WAN transformation is often comprised of multiple projects involving SD-WAN, Internet security, cloud migration, mobile access, and more. As such, it is not a quick process.

When considering your next investment in your network architecture, you should be asking yourself if the right decision is choosing a solution that addresses the current needs, or a SASE solution that can address both current and future projects requirements: future proofing.

Your questions

Frequently Asked Questions

What is SASE used for?

SASE is used to deliver converged enterprise network and security services from a globally distributed cloud service. SASE overcomes the cost, complexity and rigidity of loosely integrated and geographically bound point solutions. When combined with a global private backbone, SASE can also address WAN and cloud connectivity challenges.

What is the difference between point solution such as SD WAN, and SASE?

Point solutions address specific networking and security requirements. The need to scale and maintain each solution separately, makes IT infrastructure complex and costly. SASE is transformational when compared to to the legacy technological silos. It provides a globally based cloud service that replaces physical and virtual point solution with a cost effective, scalable alternative.

What is the difference between SD-WAN and SASE?

SD-WAN is key to the SASE platform as it connects branch locations and datacenters to the SASE cloud service. SASE extends SD-WAN to enable the WAN transformation journey that includes security, cloud, and mobility at a global scale.

Why is SASE Important?

The combination of network and security into a cloud-native service that allows IT teams to connect and secure all business locations and users in a cost-effective and scalable way is why SASE is important.

Is SASE better than point solutions such as SD-WAN & VPN?

Point solutions can only deliver the capabilities that a business needs at a growing complexity and costs. This is a result of the shift to a greater reliance on cloud computing services, and an increasing mobile workforce,SASE’s cloud-native, globally distributed architecture delivers the capabilities that businesses need to all users and locations globally, overcoming the cost, complexity and high costs associated with running legacy point solutions.

Is SASE better than SD-WAN?

SD-WAN is the first step in the WAN transformation journey. SD-WNA lacks key security functions, global connectivity functionality, as well as support for cloud resources and mobile users.A full SASE platform can support the entire WAN transformation, as it enables IT to provide the network and security functions that businesses needs in an agile and cost-effective way.

How secure is SASE?

SASE is secure end-to-end. All communication across the SASE platform is encrypted. Additional threat prevention capabilities include decryption, anti-malware, URL filtering, firewalls and IPS are natively integrated into SASE, and are globally available to all connected edges.

What is not a SASE?

SASE is a cloud service that is identity-driven, cloud-native, globally distributed, and supports all edges. Alternative architectures, such as service chaining appliances, hosting appliances and virtual machines, and telco bundles, are based on point solutions not a converged software stack designed for the cloud.
