How to replace ISA Server?

Question

proxy

It is used as a proxy for distribution of the Internet to end users and restrictions. I filter users on ip and NTLM.
I look towards squid and 3proxy .

Answer 1

The squid will be quite high-grade replacement. But then the OS will have to be changed to FreeBSD/Linux.

Answer 2

Squid, it is also available under Windows.

Answer 3

If you are interested in Windows-way analogues, then I can recommend Traffic Inspector. Simple and reliable, there are cases of operation on networks with several thousand users.
Analogues from the unix world have already been recommended to you. Squid is a very powerful program, with a million knobs and knobs that you can tweak. This is his strength and weakness. Strength - you can do almost anything, weakness - a high entry threshold for inexperienced (in the nix environment) admins, you can easily break something with careless actions without understanding the essence of the program.

Answer 4

to run squid "as is" you need to enter your local network, enter hostname and that's it.
further already in stages and restrictions, etc.
and it is not at all difficult to adjust to all sorts of bells and whistles.

Answer 5

If you do not want to change the OS, then the ISA Server is now called Microsoft Forefront
