Firewall devices, guarding internal networks from the Internet, have been a key element of network security for over two decades. Over these years, firewalls have developed in sophistication, functionality and performance—but until recently they remained physically bound to the premises of the networks they protect.

Recent years, however, have seen the emergence of Internet-located firewalls, which operate remotely from the networks they protect. These security services go by various names, such as cloud-based firewalls, security-as-a-service, and cloud security. The breadth of functionality these services offer is variable. For example, some provide very specific services, like spam filtering or virus scanning; while others offer a broad Unified Threat Management (UTM)-like service. What they do have in common, though, is that some or all of the traffic to and from the client’s premises passes through the firewall provider’s cloud-located equipment, where it is examined and filtered.

The cloud-based approach to network security is making a strong play in today’s market, and attracting a good deal of interest. This paper considers the drivers behind cloud-based security, and examines the reasons why on-premises firewalls will long continue to have a strong market presence.
