FPR3105-ASA-K9 Description
The Cisco FPR3105-ASA-K9, also called the Secure Firewall 3105 ASA appliance, is the entry-level ASA firewall in the Cisco 3100 Series. Designed for mid-sized enterprises and branch data centers, it combines Cisco’s proven ASA software with modern hardware scaling up to 20 Gbps stateful firewall throughput (10 Gbps multiprotocol).With support for 2 million concurrent connections and 90,000 new connections per second, the Firepower 3105 ASA ensures responsive protection under heavy loads. It provides 5.5 Gbps IPsec VPN throughput and accommodates up to 2,000 VPN peers, enabling secure connectivity for remote users and inter-branch networks.The appliance includes 8×RJ-45 and 8×SFP+ interfaces, expandable to 24 total ports with an optional module, allowing flexible 1G/10G deployments. High availability is ensured with Active/Active and Active/Standby HA, while dual PSU options (AC or DC) and hot-swappable fans deliver enterprise-grade resiliency.For operations, the FPR3105-ASA can be managed locally with Cisco Adaptive Security Device Manager (ASDM) or centrally via Cisco Security Manager or Cisco Defense Orchestrator (CDO), making it suitable both for standalone branch use and multi-site enterprise rollouts.
