Secure Access Service Edge (SASE)

Converging Networking and Security

What is it

Secure Access Service Edge (SASE) is an architecture that converges networking and security policies. It is a new approach to providing secure access to cloud applications, data, and services from any location and offers the scalability, performance, and cost-effectiveness required for today’s digital landscape. By building on existing SD-WAN offerings to add cloud-scale security enterprises can securely support a hybrid workforce.

How it works

As a cloud-based architecture, SASE infuses into the network, incorporating security components like Zero-Trust Network Access (ZTNA), Secure Web Gateway (SWG), and Cloud Access Security Broker (CASB).

The integration of these security components into one cloud-based solution enables enterprises to overcome the limitations of traditional on-premise security. SASE is capable of delivering consistent and comprehensive policies and security standards across the entire network.


Enabling enterprises to completely rethink their security strategy, SASE offers several benefits including:

Consistent Security Policies and Standards

Over the entire network including cloud-based applications, data, and services from any location

Increased Network Performance and End-User Experience

By eliminating the need to “bottleneck” traffic to specific locations such as company headquarters for security applications.

Cost Savings

From the ability to significantly reduce on-premise security applications which typically have a short lifespan due to bandwidth limitations

Simplified Management

Due to the integration of network and security components into one unified solution

Seamless Scalability and Flexibility

Through leveraging the software-as-a-service consumption model, enterprises can pay for what they need, when they need


With so much buzz around the term SASE, and the wide range of vendors with different security backgrounds such as network-centric, firewall-centric, security-centric, and pureplay, it’s essential for enterprises to understand SASE’s capabilities against the business problems they aim for SASE to address. This will help determine if SASE is an appropriate solution, quantify the benefits and provide the ability to compare any SASE transformation.

While completing the business use case, enterprises may find alternative security architectures like Security Service Edge (SSE) more suitable or even the stepping stone towards. From here enterprises can focus on the technical architecture and operational model, including managed services.

Coevolve has worked with clients all over the world and understands that over-complicating the business case and technical architecture can be counter-productive in the race to meet business expectations and requirements. With our Professional services we help enterprises perform tasks and offer dynamic and specialized support in the design, implementation and management of SASE solutions.
