®
Small Business ISA500 Series Integrated Security Appliance?
A. The Cisco Small Business ISA500 Series Integrated Security Appliance is an all-in-one security solution.
It combines highly secure Internet, wireless, site-to-site, and remote access with a breadth of unified threat
management (UTM) capabilities that include firewall, email, and web security, and application control to
provide the peace of mind you need in order to know your small or medium business is protected. Optimized
specifically for small and medium businesses, it is an affordable and easy-to-use solution that can be set up
to start protecting your business in minutes. It takes full advantage of Cisco Security Intelligence Operations
(SIO), which provide unrivaled threat intelligence to deliver superior threat protection. The combined power
of the ISA500’s comprehensive UTM security capabilities, easy-to-use design, and superior threat
intelligence, helps keep your organization secure, and increases both uptime and employee productivity while
minimizing risk and operational costs.

Q. What are the primary differences between the ISA550 and ISA570 appliances?
A. Listed below is a table that outlines the primary differences between the ISA550 and IS570 appliances. The
key differences between the two models is their performance and VPN scalability (refer to the Table 1). Thus,
selecting between the two models should be based on the customers’ traffic volume and the number of
remote offices and mobile workers that need to be supported. Generally speaking, for a site with total
protected users of more than 25, we suggest the ISA570 because of its higher UTM throughput. Also, if a
business is expecting to interconnect more than three remote offices to each other, we recommend the
ISA570 because it supports a larger number of site-to-site VPN tunnels than the ISA550. Similarly, if a
business needs to provide more than ten remote workers with VPN access, we recommend the ISA570.
