The Juniper SRX400 provides comprehensive network protection and operational flexibility by converging routing, switching, WAN connectivity, and firewall capabilities into one device. It supports secure zero-touch provisioning with QR-code onboarding to simplify large-scale deployments across multiple sites. Built with tamper-proof security features including a Trusted Platform Module, Secure Boot, and Hardware Root of Trust, it ensures high reliability and autonomous protection against modern threats.

Suitable for

• Securing remote branch offices and retail locations
• Deploying distributed enterprise networking and security
• Powering networked devices using integrated PoE+ ports
• Implementing reliable routing, switching, and SD-WAN connectivity

When it may not be suitable

This firewall may not be suitable for large data centers or high-density core network environments that require high-speed 10GbE or 40GbE fiber interfaces beyond the capacity of this desktop model. Additionally, environments that require active cooling systems or high-density modular expansion slots will need a different hardware class.

Key specifications

• 8 x RJ45 1GbE ports
• 2 x SFP 1GbE ports
• 2 x PoE+ ports
• AC power supply
• Junos Evo operating system
• Common Criteria certifications including NDPP, VPNEP, FWEP, and IPSEP
• Fanless desktop form factor

How to use

Connect the firewall to your power source using the included AC power supply and link your network devices to the RJ45 or SFP ports. Initial setup and configuration can be managed securely using secure zero-touch provisioning or through the Junos Evo operating system interface. Ensure the unit is placed in a well-ventilated area appropriate for fanless desktop appliances, and verify network policies and security certifications match your organizational requirements.

What to consider before purchase

• Verify that the 1GbE port density and SFP options meet your current and near-future wired connectivity requirements
• Confirm that the power budget and PoE+ capabilities are sufficient for powering your connected edge devices
• Check physical space availability for a desktop-form-factor appliance

For optimal network security and reliability, ensure the Junos Evo operating system is regularly updated and that physical placement complies with operational temperature guidelines for fanless devices.
