The Juniper SRX345 provides branch firewall protection for growing offices that need secure connectivity and room for additional users and segmented services. With high session capacity and HA support, it helps maintain consistent security and control across business-critical traffic.
Branch and site networks are under steady pressure to carry more users, more segmented traffic and more secure connectivity without adding unnecessary platform complexity.
Juniper SRX345 is a higher-capacity branch firewall for larger offices, clinics, properties and plant environments that need stronger edge control than a smaller branch model can comfortably provide.
It delivers 2 Gbps NGFW throughput and 2 Gbps IPsec VPN throughput, with 12×RJ45 and 4×SFP ports for practical deployment across mixed access and uplink requirements. HA support helps keep the security layer available where the firewall sits on a busy operational path.
That mix gives infrastructure teams room for additional users, VPNs and segmented services, while keeping branch security in a size class that fits the site. It is a practical choice when the operational need has outgrown entry-level edge capacity, but does not justify moving to a larger enterprise firewall.
If you are planning a branch refresh, our team can help assess where the Juniper SRX345 fits your environment and rollout requirements.
The Juniper SRX345 is a network security appliance for enterprise branch and edge environments, providing a compact platform for secure connectivity, policy enforcement, and operational control.
Integrated Security Gateway
The SRX345 is designed to combine network security and connectivity functions in a single branch platform.
Dual Service Alignment
Its architecture supports both security inspection and encrypted connectivity, with 2 Gbps NGFW throughput and 2 Gbps IPsec VPN throughput validating the platform role.
Wired Access Integration
The platform provides 12 RJ45 ports and 4 SFP ports to connect branch users, uplinks, and edge devices within one chassis.
Branch Deployment Fit
The SRX345 is positioned for compact enterprise environments that need centralized policy control at the network edge.
Consistent Policy Enforcement
The platform supports security policy application across branch traffic flows to maintain controlled access at the edge.
Encrypted Traffic Handling
IPsec VPN capability enables secured site connectivity for branch communications that require encrypted transport.
Operational Simplification
Combining security and connectivity functions in one device reduces the number of separate platforms that must be managed in branch deployments.
If you are planning secure branch connectivity or edge policy control, our team can help align the Juniper SRX345 to your access, VPN, and throughput requirements.

Juniper SRX345 is a higher-capacity branch firewall for larger offices, clinics, hotels and plant sites that need stronger segmentation, secure connectivity and more headroom than the SRX340 without moving to a larger enterprise perimeter platform.
In growing professional services branches, the SRX345 supports more staff, VPN users and segmented office traffic at the network edge. It gives IT teams a practical step up when the SRX340 starts to run short of capacity.
Healthcare clinics often need to separate clinical systems, admin users and guest access while keeping traffic auditable and controlled. The SRX345 fits this security tier where stronger branch capacity is needed for daily operations.
Financial branches handling transactions, voice and local breakout traffic need inspection and segmentation without overbuilding the site edge. The SRX345 provides the right level of control for regulated data flows and busier branch demand.
Hotels and conference properties must isolate guest, payment, staff and building-management traffic across one edge device. The SRX345 gives property teams enough branch capacity to keep those networks separated and manageable.
Manufacturing deployments use the SRX345 to protect plant offices, shop-floor systems, cameras and remote-access paths. It suits smaller sites that need OT and IT separation with more headroom than the SRX340.
We can help design and deploy Juniper SRX345 for branch security, segmentation and secure connectivity across professional services, healthcare, finance, hospitality and manufacturing sites.
