cSRX Container Firewall

The cSRX Container Firewall protects containerized applications and environments with advanced security services, including content security and intrusion prevention system (IPS). Purpose-built for containers, the cSRX next-generation firewall can be spun up or down in less than a second for the agility needed to manage transitory container environments like Kubernetes.

Whether you’re using a physical, virtual, or containerized firewall, Juniper delivers comprehensive visibility from edge to cloud; the cSRX adds visibility into securing applications that run in your containers. You can deploy security policies that limit access to specific applications, while intrusion prevention protects applications not easily patched. To safeguard applications from east-west traffic, the cSRX limits traffic between container segments using Layer 4–7 security policies.
