Blog Secure Access Service Edge The Right Steps to SASE: Refactor Internal Data Center Controls to Closed Loop Risk Management

The Right Steps to SASE: Refactor Internal Data Center Controls to Closed Loop Risk Management

The following is an excerpt from Netskope’s recent book Designing a SASE Architecture for Dummies. This is the sixth in a series of seven posts detailing a set of incremental steps for implementing a well-functioning SASE architecture.

Throughout this series, we repeat that the data center is just one more place people and data have to go—it’s no longer the center of attention. When you’re far along in your SASE implementation using NG-SWG, it’s time to reconsider the data center.

Perhaps a few applications that are either too unwieldy to move or too precious to let out of your sight remain in the data center. To access these applications, you could use Netskope Private Access, which eliminates the VPN while providing secure access from anywhere in the world.

As for all those other boxes and bits that have been replaced by NG-SWG services in a SASE architecture? This is your opportunity to dramatically reduce the complexity and upkeep cost of your network, with those old systems depreciating out of existence and receding into the past while you and your enterprise look forward.

True SASE yields ongoing operational cost savings. Table 5-6 shows a snapshot of what that can look like with a successful SASE implementation. Your finance people will be among the many stakeholders to thank you!
