Captivate for ISA Firewalls Looking for Beta Testers

Captive Portal for ISA Firewalls

There are many scenarios where a web proxy provider wishes to inject a special process before allowing access to the Internet. Some simple examples are:

  • Display a “Terms of Service” screen or policy page which the user must read and acknowledge.
  • On a wireless network segment, always direct the user to a custom start page first, before allowing other browsing. This could be a home page, or an external web app that collects information or payment.
    On a wireless network segment, track and log new users by IP and MAC address.
  • Require users to authenticate to ISA with a web form before allowing browsing. This is useful when you cannot control the browser proxy settings, but your users will still have accounts that are known to ISA.
  • Block access to other protocols (such as FTP, SSH, etc.) until a user passes the authorization process, then allow those protocols.


Captivate for ISA Server from Collective Software is a filter for ISA 2006 and 2004 that adds flexible captive portal functionality to your proxied networks. It directly supports all of the above scenarios, and has scriptable features to extend and enhance its functionality.

This product is currently in beta testing. Please submit comments, questions, and feature requests to the beta program. It is not mandatory to register with us before trying the filter, but we appreciate the opportunity to find out about your needs!
