Proprietary device firewall

Firewall options for the individual or for those running a small office range from native OS firewalls to special-purpose devices. Most individuals and small office/home office (SOHO) users are concerned about security but don’t want to spend more than really necessary. Obtaining a reasonable level of security for most home or small office environments is actually quite easy and cost effective. First, an understanding of the common threats facing such an environment suggests that firewall options can be simple and inexpensive.
