Porvide high security without using a proxy
Â
Hello Georgia.
Bluecoat proxy is an Internet proxy appliance. Â Although it is very robust, it can be quite pricey. Â Here are a couple of software alternatives that are free. Â All you need is to provide the hardware which, depending on how many computers you want to protect, can be anything from an old Pentium PC to a high-end server.
1. Â pfSense. Â This is a customized installation of FreeBSD that has been optimized for use as a router and firewall. Check out all its features here:
2.  SmoothWall Express. SmoothWall Express is similar to pfSense except it is based on GNU/Linux instead of FreeBSD.  Like pfSense it is full-featured, robust and best of all free. http://www.smoothwall.org/
3. Â IPCop. Â IPCop is also based on Linux. Â It is more suited for home and small office users. Â http://www.ipcop.org/
4. Â m0n0wall. Â m0n0wall is also based on FreeBSD. Â https://m0n0.ch/wall/

You saved me a lot of money,  Sollis Parallag . Thank you very much. I am currently using pfSense and thought it can't be compared with other pricey softwares, it works very great!
