FPR2140-ASA-K9 Description
The Cisco FPR2140-ASA-K9, also known as the Firepower 2140 ASA appliance or Secure Firewall ASA 2140, is the most powerful ASA-based firewall in the Firepower 2100 Series. Designed for large enterprises, data centers, and service providers, it delivers 20 Gbps stateful firewall throughput (10 Gbps multiprotocol) with 3 million concurrent sessions and 75,000 new connections per second, making it an excellent fit for mission-critical, high-capacity environments.For secure connectivity, the appliance supports 2 Gbps IPsec VPN throughput and up to 10,000 VPN peers, enabling large-scale site-to-site and remote access VPN deployments. Multi-context support (2 included; up to 40) allows service providers and MSSPs to run multiple virtual firewalls on a single physical platform.High availability features include Active/Active and Active/Standby modes, dual hot-swappable 400W AC PSUs (standard), optional DC support, and redundant fan modules, ensuring enterprise-grade resiliency and uptime. Management is intuitive with Cisco ASDM for local administration, and scalable through Cisco Security Manager or the cloud-based Cisco Defense Orchestrator (CDO) for centralized policy control.

Key Features
Highest-Performance ASA in 2100 Series
The Cisco FPR2140-ASA-K9, also known as the Firepower 2140 ASA appliance or Secure Firewall ASA 2140, provides 20 Gbps stateful firewall throughput (10 Gbps multiprotocol), making it the top ASA option in the Firepower 2100 lineup.
Massive Session & Connection Capacity
Supports 3 million concurrent sessions and 75,000 new connections per second, ensuring stability and responsiveness even in large-scale enterprise or data center deployments.
Enterprise-Grade High Availability
Provides Active/Active and Active/Standby HA, combined with dual 400W AC PSU (standard) and hot-swappable fans for continuous operations in mission-critical environments.
Extensive VPN Services
Delivers 2 Gbps IPsec VPN throughput with support for up to 10,000 VPN peers, allowing secure global remote access and inter-branch communication.
Multi-Tenant Capabilities
Comes with 2 contexts by default (expandable up to 40), ideal for enterprises, government, and MSSPs that need network segmentation or multi-customer isolation.
Flexible Management Options
Easy to configure locally via Cisco Adaptive Security Device Manager (ASDM), with centralized orchestration available through Cisco Security Manager or the cloud-based Cisco Defense Orchestrator (CDO).
Applications Scenarios
Best fit for high-capacity firewalling (20 Gbps) at data centers, WAN edges, or internet gateways, where uptime and throughput are critical.
Ideal for compliance-driven sectors that require large VPN capacity, multi-context isolation, and redundant PSU design to safeguard sensitive data and ensure regulatory compliance.
With up to 40 security contexts, centralized management, and 10G-ready interfaces, the FPR2140-ASA is a strong choice for multi-tenant managed firewall services and carrier-grade networks.
