The Cisco Secure Firewall ISA3000 Series is a ruggedized industrial firewall designed to protect
operational technology (OT) networks in harsh environments such as manufacturing plants, energy facilities,
transportation systems, and utility substations. Built specifically for industrial deployments, it combines
enterprise-grade cybersecurity with hardware engineered to withstand extreme operating conditions.
Industrial-Grade Hardware
Rugged DIN-rail mounted appliance for industrial cabinets and control rooms.
Operating temperature range from -40°C to 60°C.
Designed to resist vibration, shock, electrical surge, and electromagnetic interference.
Reliable operation in remote or unmanned industrial locations.
OT Network Security and Segmentation
Creates secure industrial DMZs between enterprise IT and plant networks.
Supports segmentation of manufacturing cells, substations, and process zones.
Helps prevent lateral movement of cyber threats within industrial environments.
Advanced Threat Protection
Powered by global threat intelligence from Cisco Talos.
Detects and blocks malware, exploits, and targeted attacks against industrial systems.
Supports advanced malware protection (AMP) for continuous file analysis and retrospective detection.
Industrial Protocol Awareness
Understands industrial control system protocols and traffic patterns.
Enables granular inspection and policy enforcement without disrupting production processes.
Integrated IT and OT Security
Part of the Cisco Secure Firewall / Firepower ecosystem.
Centralized policy management aligned with enterprise security frameworks.
Integrates with Cisco security platforms including Cyber Vision, Identity Services Engine (ISE), and SecureX.
Flexible Connectivity and Management
Multiple hardware models with copper and fiber interfaces.
Optional licenses for VPN, intrusion prevention, URL filtering, and advanced malware protection.
Management via local device manager or centralized security management platforms.
The ISA3000 Series is commonly deployed to secure industrial control networks, protect vulnerable legacy
equipment, and enforce segmentation across critical infrastructure environments.
