The Juniper SRX4100 delivers perimeter security for data centre and enterprise edge environments where strong protection and reliable connectivity are essential. It combines high-throughput inspection with high availability to help safeguard critical services without compromising performance.
As application density, encrypted traffic and segmentation demands rise together, infrastructure teams need security controls that keep pace without adding unnecessary rack or management overhead.
The Juniper SRX4100 is an enterprise firewall for campus edges, regional sites and compact data centre environments that need strong inspection in 1U space. It is built for production networks where perimeter control and internal segmentation must stay consistent under load.
With 60 Gbps firewall throughput, 20 Gbps NGFW throughput and 12 Gbps SSL inspection throughput, the platform is sized for traffic that is both high volume and heavily encrypted. Its 10,000,000 maximum concurrent sessions give it the headroom needed for large user populations, distributed endpoints and persistent application flows.
The SRX4100 helps security teams apply inspection and segmentation at the point where traffic enters and exits the environment. That supports clearer policy enforcement, steadier performance and a more practical security tier for sites that need capacity beyond mid-range models.
Speak to our team about the Juniper SRX4100 if you are planning edge security for a dense site, a regional hub or a space-constrained data centre.
Juniper SRX4100 is a security platform for enterprise and service provider edge environments, delivering centralized policy enforcement, resilient connectivity, and scalable protection for demanding network deployments.
High-Throughput Security Processing
The platform is designed to sustain large inspection workloads with firewall throughput validated at 60 Gbps.
Session Scalability
It supports high connection density for busy environments with up to 10,000,000 concurrent sessions.
Edge Deployment Fit
Its architecture is suited to security enforcement at the network edge where traffic growth and policy complexity must be managed together.
Enterprise Traffic Control
It provides a centralized control point for protecting and segmenting enterprise network traffic across connected environments.
High Availability Support
Built-in HA support helps maintain service continuity by enabling resilient security operation in active network environments.
Operational Continuity
The platform is designed to reduce disruption during maintenance or failure events through availability-oriented deployment models.
Policy Enforcement Consistency
Security policy can be applied consistently across traffic flows to preserve control as conditions change.
If you need edge security that can handle growth, continuity, and policy control, our team can help align the SRX4100 to your network architecture.

Juniper SRX4100 is an enterprise firewall for high-throughput edge security in finance, healthcare, data centres, manufacturing, and energy environments. It fits teams that need stronger inspection and segmentation without moving to a larger SRX4200-class deployment.
Financial institutions use the SRX4100 at campus or regional edge sites where regulated traffic, partner links, and secure user access all converge. It gives security teams the throughput needed to inspect flows without creating a bottleneck.
Healthcare networks deploy the SRX4100 at larger hospital edges to separate clinical systems, guest access, and administrative traffic. It supports busy operational environments where auditability, user density, and partner connectivity all place pressure on the firewall tier.
For data centres, the SRX4100 suits perimeter and DMZ layers that must enforce policy at speed while staying within tight rack space. It helps avoid firewall congestion where east-west and north-south traffic are both active.
Manufacturing teams place the SRX4100 between office IT, production networks, cameras, and remote access paths. The added capacity is useful where segmentation must be consistent across large sites and plant operations cannot tolerate weak perimeter control.
Energy and utilities organisations deploy the SRX4100 at regional hubs to protect OT, IT, and corporate WAN connections. It supports controlled inspection and segmentation where remote operational access and site-to-site traffic need tight governance.
We can help design and deploy SRX4100 security for finance, healthcare, data centre, manufacturing, and utility environments, with sizing and deployment support aligned to your traffic profile, resilience needs, and staffing model.
