Napera's appliance works in conjunction with Microsoft's Network Access Protection (NAP), and will support three different operating systems: XP with Service Pack 3, Vista, and Mac OS X. It allows for guest and identity-based access. It installs a small agent on each device that is used for the health check, and to help secure your computer and guide you with the remediation process. It also works with both wired and wireless networks too. Category: Endpoint network security appliance Pricing: $3495 for 24 gigabit managed ports. There are also stackable add-ons when you have larger networks. While this is expensive compared to other managed switches (Dell sells one for $500), it is a bargain when compared to full-featured NAC products from Cisco and others. Pros: Easy to use and setup No Windows servers required to operate NAP Cons: Only Windows XP with SP3supported Browsers must be at least IE7, Firefox 2 or Safari 3 Windows agents use Active X to install themselves Napera Networks Inc 9423 SE 36th St Mercer Island, WA 98040 425 747 7142 http://www.napera.com
