By implementing networking and security in a thin and hardened software layer that runs directly on the bare metal of their servers, VMware customers are uniquely able to configure their networks and enforce security policies at the lowest level of their software stack.

Guard Against Threats from Anywhere

VMware NSX enables micro-segmentation, which defines and enforces network security policies consistently, on any workload hosted anywhere. This approach makes VMware NSX ideal for securing intra–data center network traffic, isolating disparate networks, and simplifying networks that would otherwise require complex access policies. This inline process is invisible to users and keeps potential security threats out of sight and out of mind.

Secure Applications from the Inside

VMware AppDefense is a data center endpoint security product that protects applications running in virtualized environments. Unlike other security products, AppDefense understands an application’s intended state and behavior and monitors it for changes that indicate a threat. When a threat is detected, AppDefense automatically responds by alerting your security operations center so the threat can be eradicated.

Ensure the Security of Digital Infrastructure Around the World

VMware maintains best-in-class security standards in all facets of our products and cloud services, and aligns with the major compliance certifications. Modernize, scale, and automate your digital infrastructure with agility, and without making any concessions in security.

Keep Virtual Machines Safe

VMware vSphere was developed from the ground up to run virtual machines securely. It incorporates powerful features that address the security concerns of the most demanding data center environments and provides security mechanisms at multiple layers, from the virtualization layer to software design. 

What NSX Enables


VMware NSX Data Center is the network virtualization platform for the Software-Defined Data Center (SDDC), delivering networking and security entirely in software, abstracted from the underlying physical infrastructure. Running in the VMware ESXi hypervisor, NSX Data Center enables the Virtual Cloud Network, providing pervasive, end-to-end connectivity for your apps and data, wherever they are.


VMware NSX-T Data Center provides support for bare-metal hosts, in addition to heterogeneous hypervisor and container environments running on-premises and in public clouds.


VMware NSX Cloud, together with NSX Data Center, provides a uniform operational model across public cloud and on-premises deployments. This allows cloud IT to simplify and scale operations across a growing number of virtual networks, availability zones, regions, and clouds. NSX Cloud is an extension of NSX Data Center technology that brings the NSX networking and security framework to cloud-native applications for a consistent management paradigm across private and public clouds.

AppDefense Proactive Security

"By combining services, VMware offers a technology suite that is more than the sum of its parts and points to the future of network security."



VMware AppDefense proactively protects virtualized data center endpoints and applications by monitoring them for suspicious changes from their Intended state.

Protects itself from attacks

AppDefense installs in the hypervisor-an isolated environment that protects it from being compromised. App Defense uses the privileged position of the hypervisor to provide the best context for monitoring applications and detecting anomalies.

Understands your applications

AppDefense monitors the intended state of applications based upon their function. A web server, for instance, is followed to see which web services are used when running. This information is collected, stored, and monitored to detect unexpected changes.

Automates precision responses

When a threat is detected, AppDefense coordinates with vSphere and VMware NSX Data Center to automatically isolate and halt altered endpoints.

Gartner Peer Insights reviews constitute the subjective opinions of individual end users based on their own experiences, and do not represent the views of Gartner or its affiliates.


“VMware is the only vendor that is even close to offering a complete hyper-segmentation service. NSX micro-segmentation combined with AppDefense provides something akin to hyper-segmentation.”


“The Virtual Cloud Network is VMware’s best architecture to date, as it gives its customers the ability to deploy the right network and security services wherever they want, whenever they want, without disrupting business operations.”

Network World

“NSX returns to my list of winning products for another year because VMware keeps ratcheting up the excellence. NSX makes automating network security easy and integrates this automation with existing virtualization management tools. vSphere is still the best virtualization platform on the market from a feature and ecosystem perspective.”
