The Cisco Secure FPR4245 delivers high-end firewall protection for data-centre environments where security inspection must scale with heavy traffic. As the highest-capacity model in the Secure Firewall 4200 series, it combines threat inspection with resilient connectivity to keep critical workloads protected without becoming a bottleneck.
Dense traffic, segmented workloads and remote access paths put constant pressure on security controls to keep pace without adding friction to core operations.
Cisco Secure FPR4245 is built for data-centre, service-provider and large enterprise edge environments where inspection load is high and policy needs to stay close to critical traffic. It delivers 180 Gbps firewall throughput, 90 Gbps NGFW throughput and support for 40,000,000 concurrent sessions.
That capacity gives infrastructure teams headroom for heavy north-south and east-west flows, plus the VPN and segmentation demands that come with mixed application estates. HA support helps keep the platform aligned with availability expectations in production.
The result is a firewall role that can absorb growth in traffic and policy complexity without forcing an early refresh or multiple appliances. It gives teams a compact platform for stronger inspection, clearer separation and more predictable edge operations.
Our team can help assess Cisco Secure FPR4245 for your environment and map it to the traffic patterns, availability targets and security controls you need.
Cisco Secure FPR4245 is a security platform for enterprise network environments that combines firewall deployment with resilient operations and high-capacity traffic handling for consistent perimeter control.
High-Throughput Inspection
The platform is designed to sustain firewall processing at up to 180 Gbps, supporting demanding network security deployments.
Large Session Capacity
It supports up to 40,000,000 concurrent sessions to maintain stateful inspection across extensive user and application activity.
Enterprise Network Fit
Its architecture is suited to security enforcement in large, connected environments where consistent traffic inspection is required.
Deployment Flexibility
The platform can be positioned for enterprise firewall use where performance and operational consistency must be maintained together.
High Availability Support
Built-in HA support helps maintain service continuity by enabling resilient firewall operation in paired deployments.
Operational Continuity
The platform is structured to support ongoing security enforcement without introducing unnecessary interruption to network traffic handling.
Controlled Security Posture
It provides a foundation for centralized enforcement that aligns security policy with enterprise network operations.
If you are planning a high-capacity firewall deployment with resilience requirements, our Cisco experts can help match Cisco Secure FPR4245 to your network architecture and operational goals.
The Cisco Secure FPR4245 is built for heavy security inspection at high-traffic edges, internal segmentation points and VPN hubs where the firewall must keep pace with demanding application, partner and remote-access flows without becoming a bottleneck.
In data centres running mixed application tiers and tenant networks, teams need inspection that scales with north-south and east-west traffic. The FPR4245 gives security headroom for dense environments where policy separation must stay close to critical workloads.
Telecom operators often carry subscriber, management and customer traffic through the same security layers. The FPR4245 fits these roles when inline protection must sustain high throughput while preserving enough margin for busy service-edge traffic.
Finance teams need strong perimeter control, encrypted-traffic inspection and secure VPN access around sensitive applications. The FPR4245 supports these environments when audit expectations are high and security controls must not slow regulated user and application traffic.
Software development estates use the firewall to isolate dev, test, production and remote-access traffic across cloud-adjacent environments. The FPR4245 suits teams that need clear separation and protected internet access without adding friction to delivery pipelines.
Healthcare organisations depend on secure access to EHR, imaging and external partner links while clinical services remain responsive. The FPR4245 is a practical choice where inspection, segmentation and remote access must stay in step with care workflows.
Our team can help design and deploy Cisco Secure FPR4245 firewalls for data centres, telecom edges, finance, software development and healthcare environments, with sizing and deployment support shaped around your traffic pattern and recovery needs.
