Cisco CISCO861-K9 Full Product Description

1. Short Overview

Suffix Breakdown

• CISCO861: Official full PID part number for the Ethernet-only base model of Cisco 860 Series small business ISR
• -K9: Permanent Cisco cryptographic license bundle, enabling AES-128/AES-192/AES-256, 3DES, DES, SHA-1/SHA-2, IKEv1/IKEv2 full encryption suite with hardware offload supportCisco

Core Differentiators

1. vs wireless variant CISCO861W-GN-A-K9: CISCO861-K9 omits built-in 802.11n MIMO wireless AP hardware; wireless SKUs add dual-band WLAN for on-site mobile client accessCisco.
2. vs ADSL integrated CISCO867-K9 series: 867 models integrate onboard ADSL2/2+ POTS modem; CISCO861-K9 relies solely on Ethernet-based broadband uplinks (cable, fiber media converter, metro-Ethernet).
3. vs compact C812-K9 desktop router: C812 only has two standalone Gigabit ports without internal switch; CISCO861-K9 integrates a 4-port managed FE switch to connect multiple local endpoints without external switches.
4. vs industrial hardened C819HG series: CISCO861-K9 is commercial indoor desktop chassis with standard narrow temperature range, not certified for extreme industrial, vehicle or outdoor cabinet deployments.

5. Typical Deployment Scenarios

1. Small Retail Store Secure Broadband Gateway
   The integrated 4-port LAN switch connects POS payment terminals, office PCs and IP surveillance cameras; persistent IPsec VPN tunnels securely transmit transaction data back to retail corporate data centers, while the zone firewall isolates sensitive payment systems from public internet threats.
2. Tiny Regional Satellite Office Branch Router
   Cost-effective wired ISR for small remote offices with cable/fiber Ethernet broadband uplinks, supporting up to four local wired endpoints without purchasing external access switches.
3. Teleworker Home Office Secure VPN Gateway
   Deployed at remote employee residences to establish encrypted Easy VPN tunnels back to corporate headquarters; stateful firewall protects home office devices from internet malware and unauthorized access.
4. Low-Density Unmanned IoT Site Wired Edge Router
   Aggregates small-scale IP cameras and environmental monitoring sensors via FE LAN ports, maintaining persistent encrypted IPsec tunnels to central cloud or on-premises management platforms.
5. Secondary Backup Broadband Router
   Used as standby wired gateway to provide business continuity during primary network equipment outages, supporting fast failover for critical POS or office communications.
