Microsoft's ISA Server provides a sophisticated, application-layer aware firewall that can guard your business network from external and internal attacks. ISA Server performs deep inspection of Internet protocols such as HTTP, which allows ISA Server to uncover many threats that can get past conventional firewalls. The combined firewall and VPN design of ISA Server supports stateful filtering of all VPN traffic. ISA Servers are the centerpiece of Microsoft's network security strategy, and NOVA's Microsoft certified engineers and security consultants can help you bolster your network security through expert deployment of ISA Servers.
