If you buy it with &quot;Security Plus&quot;. But the ASA5505 does not do intrusion prevention. Might be worth the upgrade to the 5510.<br />
<br />
Thanks!

Hello,<br />
I am looking for a new firewall to provide ISP failover. I have a cable model and a DSL line. The cablem modem is faster and is the primary, but does fail in bad weather.<br />
<br />
Do I need a ASA 5505 or ASA5510?<br />
<br />
Thank you!

Cisco ASA 5505 or 5510 - For ISP FailOver

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
