Gartner introduced Secure Access Service Edge or SASE in 2019 in a research note titled “The Future of Network Security Is in the Cloud.” SASE is a new enterprise networking technology category, and it is a combination of SD-WAN capabilities comprising of various security services delivered through a cloud-based delivery model. It offers highly customizable policy-based control for performance and security to simplify network management.
SASE combines networking and security to improve app performance, reduce infrastructure complexity, and protect confidential data. However, only a few suppliers can provide a complete SASE portfolio with supreme networking and security capabilities as they struggle to integrate various technology acquisitions to build a reliable solution.
SASE security solution helps to strengthen enterprise network security. The SASE market is expected to grow at a compounded annual growth rate of 116%. SASE is based on a suite of dynamic edge security and connectivity capabilities delivered through the cloud. Here are five essential things that you need to know when considering SASE for your business.
· Define Your Needs
To build a SASE architecture in your business, you need to consider the SASE framework carefully. It defines various network and security functions, including traffic shaping, latency optimization, Firewall as a Service (FWaaS), Zero-Trust Network Architecture (ZTNA), Secure Web Gateway (SWG), and more. Some vendors cover most of these SASE functions in a ‘single-pass solution. Hence, your vendor will provide you with SD-WAN and Security solutions. However, while this offering may sound convenient, it doesn’t mean that you will receive the best solution out there. In a ‘best of breed’ platform, you integrate your business with Network and Security providers. It leverages your proximity to the PoPs (point of purchase). It allows you to pick up the choice of vendor for each feature. Depending on your need, choose the right vendor.
· SASE Exists At The Edge
You can deploy SASE natively in the public cloud or at the Edge of the cloud. Edge Cloud is an interchangeable cloud ecosystem that encompasses the storage and computes assets located at the Edge. Finding SASE on the edge cloud allows you to adapt to changing needs securely and in real-time.
· Proximity Is Key
Devise an appropriate strategy that allows you to use the SASE to execute an application and deliver data as close to the end-user as possible. It helps to minimize the time it takes to provide web content to users. SASE should enable you to optimize the Applications, Data, and Users and the interactions among them.
· Long-Term Vision And Viability
While choosing a SASE vendor and architecture, ensure that your vendor has developed the SASE solution with long-term vision and the agility to rapidly adjust to new market requirements. The SASE architecture should be able to integrate the upcoming technology smoothly.
· Know Which Solution Fits
Ensure that your vendor is not selling the SASE solution based on false claims about its use cases. No single SASE solution will likely fit into all use cases. You need to prepare a list of your organization’s needs and priorities and match it with various vendors’ SASE features. Do not fall prey to the marketing gimmicks and choose a SASE solution wisely.
Keep in mind the points mentioned above to choose the right SASE. It converges networking and security, optimizing access performance, minimizing operational complexity, and enhancing your business’s security posture.
