Cisco ASA Firewall Review

Powerful firewall and VPN device that is highly stable with multiple contexts but has latency and NATing issues

Valuable Features:

-Powerful firewall provides multiple contexts. -Highly stable firewall for campus traffic with no shutdown and zero maintenance compared to the Juniper SRX family which performs like a software firewall after 3 months of operation and did not allow the administrator to login. -Easy to use both GUI and command line. Also it may be more easily used through a management application like Cisco ASDM

Room for Improvement:

-Latency and delay due to configuration and monitoring of multiple VLANS and traffic -Increases the delay as the firewall and IPS polices increase -We faced usually a problem with NATING

Other Advice:

Cisco delivers a powerful firewall -- it’s not just a firewall but also a modular device that can deliver IPS hosting and wireless LAN controller as well. It also provides site to site VPN and remote access VPN services.
