Can I deploy only the firewall functionality?
Yes, you can deploy the firewall as a locked-down security solution. As part of the setup process, you can select the ISA Server mode: firewall, cache, or integrated. In firewall mode, you can secure network communication by configuring rules that control communication between your corporate network and the Internet. You can also publish internal servers, securely sharing data on your internal servers with Internet users. In cache mode, you can improve network performance and save bandwidth by storing commonly accessed objects closer to the user. You can also publish internal Web servers. Integrated mode combines the features of both firewall and the cache, ensuring security and enhancing performance. In all modes, you can benefit from ISA Server enterprise policy management, real-time monitoring and reporting features.
