As workloads move to the public cloud, they introduce challenges around not only how to secure the data, but also around securing communication between workloads running in the cloud and other locations.
Network and security professionals must perform a delicate balancing act, delivering the benefits of cloud technologies without undermining the security of the organization. This challenge can only be met by a security solution that keeps pace with evolving threats while matching the agility and scalability of cloud environments—without sacrificing reliability, visibility, and control.
Juniper Networks addresses these challenges head-on by extending the capabilities of the award-winning Juniper Networks® SRX Series Services Gateways as a cloud-native virtual firewall for Microsoft Azure, empowering security professionals to deploy and scale firewall protection for workloads running within Azure. The Juniper Networks vSRX Virtual Firewall offers unparalleled next-generation firewall (NGFW) security that includes intrusion prevention system (IPS), malware protection, app control, and on-demand threat detection. The vSRX also supports communications security with secure SD-WAN, Azure virtual networks, and SD-LAN for secure segmentation between workloads.
The vSRX for Azure automated provisioning capabilities allow network and security administrators to quickly and efficiently provision and scale firewall protection to meet the dynamic needs of cloud environments. By combining the vSRX with the power of Junos Space® Security Director or Contrail® Service Orchestration, administrators can significantly improve policy configuration, management, and visibility into both physical and virtual assets from a common, centralized platform.
Juniper is committed to helping customers realize the value of their existing investments, and has invested in interoperability for all of its SRX Series firewalls. In addition to Security Director and Contrail Service Orchestration, the vSRX also supports OpenContrail® as well as other third-party management solutions. The vSRX can also be integrated with other next-generation cloud orchestration tools such as OpenStack, either directly or through rich APIs.
In addition to public cloud and traditional virtualization use cases, the vSRX allows service providers and enterprises to deploy a secure SD-WAN fabric with edge defenses that are adaptable to any site’s individual needs, while also providing the flexibility to defend virtualized and service-oriented applications wherever they exist throughout the network.
Security Director can manage up to 25,000 SRX Series firewalls—whether physical, virtual, or containerized—from a single management instance. This allows organizations to use a single platform to manage, automate, and orchestrate network security, virtualization, and interconnectivity, from endpoint to edge and every cloud in between.
Architecture and Key Components
The vSRX on Azure can secure communications between workloads running in different virtual networks and/or an on-premises data center. The vSRX VPN capability allows for secure connectivity between virtual network peering in the same Azure region and global virtual network peering across Azure regions. This allows the vSRX to offer secure connectivity between Azure virtual networks without having to send data flows over the Internet, which minimizes cost, latency, and availability concerns.
vSRX Virtual Firewall can make use of multiple connectivity options to securely connect sites—whether virtual or physical—to the enterprise WAN fabric. Secure connectivity can be extended to include other data centers (such as collocation of third-party cloud deployments) that may need to securely communicate with the cloud workloads.
To access applications hosted in the Azure cloud, branch offices traditionally leverage connections back through corporate campus locations and then access the applications in Azure. In this situation, secure SD-WAN can be deployed at the branch and use vSRX on Azure to activate a more optimized solution for connectivity that goes directly to Azure, bypassing the need to access cloud applications through the campus network.
A vSRX deployed in Azure can act as an SD-WAN spoke or hub, offering secure access between campus and branch locations and Azure directly as part of a larger SD-WAN deployment. It can also act as the SD-WAN hub where it provides secure access to cloud resources hosted in Azure, becoming the central point for regionally based Internet breakouts. This allows vSRX on Azure to not only secure workloads, but also provide secure SD-WAN connectivity that fits changing business needs.
Firewalls protect workloads, but not all firewalls are created equal. With vSRX on Azure, customers can ensure policies are consistently deployed across their entire network, whether those workloads operate on premises, in the public cloud, or at the edge. Customers already using SRX Series firewalls in their networks can easily extend those policies to vSRX Virtual Firewall operating in the public cloud or elsewhere.
vSRX supports the creation and deployment of firewall policies using metadata tags, which facilitates security automation and reduces the number of rules required during initial implementation or ongoing maintenance. This metadata gives security administrators greater visibility by providing a full network view based on the metadata tags, meaning they are no longer limited to IP address-based rule management and filtering.
In addition to policy enforcement, the vSRX provides advanced security services, including IPS, antivirus, and anti-malware, to identify and block advanced threats targeting workloads hosted in the Azure cloud.
To secure communication and ensure workload segmentation on Azure, the vSRX can be deployed to enforce policies regarding which communications should be allowed between workload segments. The vSRX facilitates granular network segmentation and control by applying security policies at the virtualized workload level. From a security perspective, the more granular level at which a threat can be blocked, the more effective it will be containing the threat’s propagation.

Advanced Security Services
Implementing nonintegrated legacy systems built around traditional firewalls and individual standalone appliances and software is no longer enough to protect against today’s sophisticated attacks. Juniper’s advanced security suite enables users to deploy multiple technologies to meet the unique and evolving needs of modern organizations and the constantly changing threat landscape. Real-time updates ensure that technologies, policies, and other security measures are always current.
The vSRX for Azure delivers a versatile and powerful set of advanced security services, including IPS, malware protection, app control, and content security.
Intrusion Prevention System
IPS for vSRX for Azure controls access to IT networks, protecting systems from attack by inspecting data and taking actions such as blocking attacks as they are developing or creating a series of rules in the firewall. IPS tightly integrates Juniper’s applications security features with the network infrastructure to further mitigate threats and defend against a wide range of attacks and vulnerabilities.
Juniper Advanced Threat Prevention
Juniper Advanced Threat Prevention integrates with the vSRX for Azure to provide dynamic, automated protection against known malware and advanced zero-day threats, resulting in nearly instantaneous responses.
