Palo Alto Networks vs Juniper SRX -- Firewall & NGFW Compared

Palo Alto Networks vs Juniper SRX

Juniper SRX competes as a security gateway with strong networking DNA, making it ideal for environments where advanced routing and security must converge on a single platform. Palo Alto Networks is the stronger pure NGFW with superior threat prevention and application visibility, but Juniper SRX excels when enterprise-grade routing capabilities like BGP, OSPF, and MPLS are as important as firewall security.

The Verdict

Choose Juniper SRX if advanced routing capabilities and Junos OS expertise are central to your requirements, particularly in service provider or complex network environments. Choose Palo Alto Networks if security efficacy, application visibility, and threat prevention are your primary decision criteria and you need a purpose-built NGFW.
