Keep branch and small-office traffic under control with a firewall platform designed for consistent perimeter enforcement. Cisco Secure Firewall 220 Appliance, ASA gives IT teams a compact security point for controlling access, segmenting traffic, and supporting remote connectivity where a full enterprise chassis would be unnecessary. This model is a strong fit when you need Cisco firewall architecture in a smaller footprint and want to maintain familiar ASA-based operations. It supports the kind of day-to-day security posture that matters in distributed environments: clear policy boundaries, controlled exposure to the internet, and a stable platform for protecting business applications. For organizations standardizing on Cisco security, the 220 Appliance helps extend the same operational discipline across branch locations, remote sites, and smaller network segments. It is built for teams that value predictable deployment, manageable scale, and a trusted platform for enforcing access rules at the edge.
