I have a customer who is currently using a Pix 506E. Since this device is reaching its end-of-life I am going to replace this Pix with an ASA5510. This client wants Content Filtering to be a feature on the new firewall. They want to be able to block streaming media, nudity, social networking sites, etc. What kind of license or module must I use on the ASA to allowing me to do content filtering as well on this ASA. I was reading about the Content Security and Control Security Services Module below: Seems expensive.
Is there other ways to do this besides purchasing the module like maybe websense? is there a special license needed for it? Thanks
