What is the Juniper vSRX Virtual Firewall?

The Juniper vSRX Virtual Firewall is a next-generation firewall software that delivers the same advanced security and networking feature set as physical Juniper SRX Series firewalls, in a virtual form factor.

Built on Junos OS, vSRX is engineered to secure virtualised workloads across multi-tenant infrastructures while integrating with cloud orchestration platforms, SDN solutions, and centralised management tools. Its virtual form factor enables flexible deployment and scaling to match dynamic traffic and security demands.

Deployment and Integration

vSRX can be deployed on standard x86 hypervisors (e.g., VMware ESXi, KVM) and major public cloud marketplaces (AWS, Azure, GCP), offering flexible licensing options including Bring-Your-Own-License (BYOL) and pay-as-you-go.

Juniper vSRX works with SDN and NFV platforms, such as Juniper Contrail and other third-party tools, enabling automated deployment of security policies and flexible routing of traffic between virtual network services.
