The security needs for home and business firewalls are different because of how hackers perceive their value. Businesses are more valuable targets to attackers than home users as they hold large amounts of data such as client details and trade secrets that can be sold. This gives hackers added incentive to coordinate complex, targeted, attacks not often seen on home networks.
Business-grade firewalls come with a much larger set of features needed to defend against these sophisticated attacks. The advanced firewalls utilized by businesses can provide many extra security features including managing individual ports, filtering packets, SSL inspection, geoblocking, and many more.
