Cisco ISR 4331 Router Description:

Cisco ISR4331/K9 Integrated Services Router is a cornerstone of modern network infrastructure, engineered to meet the dynamic demands of enterprise branch offices. As a part of the revolutionary Cisco 4000 Series ISRs, the ISR 4331 consolidates essential IT functions into a single, highly secure, and flexible platform, empowering your organization with superior performance and simplified management.

Optimized Performance for Application-Aware Networking: Experience blazing-fast network performance with the ISR 4331, offering an aggregate throughput of 100 Mbps, upgradeable to an impressive 300 Mbps with a performance license. Powered by a multi-core processor and a high-speed backplane, this router can run multiple concurrent services—including encryption, traffic management, and WAN optimization—without compromising data throughput. This ensures your critical applications always receive the bandwidth and prioritization they need.

Integrated Security for Comprehensive Threat Defense: Protect your branch network from evolving cyber threats with the ISR 4331’s integrated security features. With built-in capabilities such as firewall, VPN support (IPsec, DMVPN, FlexVPN), intrusion prevention, and advanced application inspection and control, this router safeguards your data and network assets. You can minimize the need for separate security appliances, simplifying your security posture and reducing operational overhead.

Modular Design for Unmatched Flexibility and Scalability: The ISR 4331 boasts a highly modular architecture, featuring two Network Interface Module (NIM) slots, one Enhanced Service-Module (SM-X) slot, and an Integrated Services Card (ISC) slot. This modularity allows for flexible deployment options and future scalability, enabling you to easily integrate additional WAN connectivity, voice and video services (with optional PVDM4 DSP modules), compute resources (with UCS E-series server modules), and more. Adapt your network as your business grows without costly forklift upgrades.

Enhanced Network Services & Virtualization Ready: Consolidate various IT functions onto a single, high-performance platform. The ISR 4331 can host virtualized network functions and applications, offering unprecedented agility and freedom of choice in deploying services. It supports advanced features like Cisco Intelligent WAN (IWAN) and is SD-WAN enabled, dynamically routing traffic across the “best” links for optimal application experiences. This ensures efficient bandwidth usage, improved application performance, and enhanced data privacy across diverse WAN transport links.

Simplified Management & Reliability: Leverage Cisco IOS XE Software for robust and feature-rich routing. The ISR 4331 is designed for easy manageability, integrating with Cisco DNA Center for centralized control, automation, and analytics across your network. Cisco’s renowned reliability ensures continuous uptime and consistent performance for your business-critical operations.
