SASE has never been more relevant. The accelerated and sustained transition to a hybrid workforce has made converged cloud networking and cloud security a necessity.
Work is no longer conducted at just one place. The branch has evolved, and the “trusted perimeter” has dissolved. Both users and applications are everywhere—now more than ever. This new normal requires secure and optimized access to the data center and cloud services for users to enable a productive, anywhere workforce.
Highly distributed workloads and users require a software-defined and converged architectural approach for secure, agile, and optimal application access from branch and campus locations. Combining cloud-delivered SD-WAN with security services, SASE is the ultimate architecture to provide you with the agility, simplicity, security, and scale you need to embrace cloud and SaaS.
Better resiliency is crucial when you have many small branch offices. With limited bandwidth at remote locations, you need cost-efficient and high-performing connections that are easy to deploy and manage.
SASE stands for Secure Access Service Edge.
An ideal SASE solution provides consistent, secure access from anywhere, but not all vendors are up to the challenge. Look for a SASE vendor that can deliver integrated networking and security to reduce operational complexity. A SASE solution should also take a cloud-first approach, offer robust intrinsic security capabilities, including Zero Trust Network Access (ZTNA) and scalable network capabilities like cloud-based SD-WAN.
Adoption of SASE enables benefits such as better application performance and improved data security, enabling consistently optimized network access from anywhere. In addition, the best SASE solutions deliver operational simplicity and are based on a cloud-first approach.
SASE solves many challenges, such as operational complexity and compromised cybersecurity. However, since SASE combines networking and security, it can be a challenge to implement when teams are siloed. Selecting vendors can also be an issue, especially when multiple products or vendors are required.
Businesses are moving applications to the cloud while allowing users to access them remotely. At the same time, companies must protect themselves from ever-evolving security threats. SASE allows IT to support these changes by providing the same experience whether users are in the office or outside it. SASE combines network and security services to enable a unified edge and cloud service model.
If you're ready to adopt SASE, make sure your IT teams are prepared. Since SASE combines networking and security functions, siloed networking and security teams present a hurdle to adoption. It's also important to find a vendor that offers flexibility and ideally stick to one or two vendors to reduce complexity.
Capabilities of SASE include:
SASE is delivered as a cloud service with a multitenant architecture. Direct cloud access is offered through globally distributed points of presence (PoPs).
SASE is cloud-delivered networking with security. SASE components include software-defined wide area network (SD-WAN), Secure Access, Cloud Web Security and Cloud Firewall.
Security Services Edge (SSE) is a subset of a SASE that includes just the security components. A full SASE solution requires both network and security functionality to connect distributed users to distributed applications securely, quickly, and reliably.
