Secure Access Service Edge
Provide the levels of security and access control that digital organizations need, delivering immediate, uninterrupted access for your users, no matter where they’re located.

What is Secure Access Service Edge (SASE)?

Secure Access Service Edge (SASE) is still a relatively new architectural concept that converges WAN capabilities, i.e. SD-WAN, and Security Service Edge (SSE) functions, such as Secure Web Gateway (SWG), Cloud Access Security Brokers (CASB), and Zero Trust Network Access (ZTNA), into a unified, cloud-native service.

The requirement is being driven by digital transformation and shifts the focal point to the identity of the user and/or device rather than the Data Center.

This supports the dynamic secure access and performance needs organizations have today across all edges (WAN, cloud, mobile, and IoT), regardless of user, location or application in a Work From Anywhere world.

However, designing the perfect SASE architecture won’t happen overnight, and many challenges will arise for the following reasons.

Siloed People

Building a SASE architecture requires networking and security teams to work very closely together.

Yet there’s traditionally been a lack of co-ordination between both sides, and a failure to understand each other’s priorities.

This has often resulted in a history of tension.

Close co-operation will therefore be required across these teams at management level to ensure the security team understands WAN processes, and vice versa.

Siloed Processes

Continuing the siloed theme, a recent global survey concluded that over 55% of security decisions were made in separate teams to those responsible for the WAN, and only 16% of security teams were involved in WAN projects from the outset.

The main reason was that the network team often sees the security team as an obstacle.

Tool Proliferation

Most organizations are already suffering from networking and security tool proliferation, so agreeing on a rationalized standard that serves both teams across a SASE platform won’t be easy.

Further, because of the fast-changing landscape of security tools and security threats, at least 35% of teams want the ability to drop tools from their portfolio and quickly adopt others when and where gaps arise.

While some flexibility in a SASE platform will be required, such a frequent switch-out of technologies is likely to create unnecessary inefficiencies.

Take a different approach to SASE

Successful I&O leaders are approaching SASE as a roadmap exercise and are defining their path over multiple years as one converged networking and security team.

Our Approach to SASE
