What is SASE?

SASE is the convergence of cloud networking and cloud security for simplicity, scalability, flexibility and pervasive security. Combining network security functions with WAN capabilities, SASE delivers secure, optimal and automated access to applications and workloads in the cloud by extending software-defined networking and security to the doorstep of major IaaS and SaaS providers. Regardless of the location of users and applications, SASE provides unified secure access from a single management platform.

SASE is Cloud

Meet the dynamic needs of a distributed, digital workforce.

Benefits of SASE

SASE secures the newly distributed workforce and network edge so people, apps and devices can communicate from anywhere. The VMware SASE advantage is a unified edge and cloud service model with a single place to manage business policy, configuration, and monitoring.

Cloud-First Approach

Enable multi-cloud interconnect with VMware SD-WAN cloud gateways. VMware SASE services are completely cloud-based and easy to consume and scale. 

Intrinsic Security

Protect against attacks at all levels with robust security, including contextual access, network security, application protection and workload encryption.

Assured Application Performance

Ensure user access and an optimized experience for mission-critical applications, even with a single link and degraded network conditions.

Operational Simplicity

Simplify day 0-1 operations with automation and zero-touch provisioning. Transform day 2 operations and self-heal your network with actionable insights.

SASE Components

SASE architecture works together to provide a cloud-first approach, application quality assurance, intrinsic security, and operational simplicity. The components of SASE include: software-defined wide area network ( SD-WAN), zero trust network access ( ZTNA), cloud web security (CWS), and artificial intelligence for IT operations (AIOps).


Decouples networking services from the underlying networks, allowing application traffic to be carried independently of the underlying physical or transport components.

Cloud Web Security

Provides a set of cloud-based security services that include a secure web gateway (SWG), cloud access security broker (CASB), data loss prevention (DLP), and remote browser isolation (RBI).

Zero Trust Network Access

Shifts from network-centric security to an approach based on identity, location and context that “trusts no one,” granting authorized resources on-demand.


Reduce network troubleshooting and optimization and improve the end user experience through network analytics, problem isolation and actionable remediation enabled by AI/ML.

Frequently Asked Questions

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:

  • Cloud-native, multitenant platform for on-ramp to public and private cloud.
  • Unified secure access for branch, campus, and mobile users.
  • Contextual access based on user identity, device location, and security posture.
  • Web and security policy control.

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.
