Anti-spam, anti-virus and content filtering ($500-upwards)

  • Competitive features like those in Gibraltar (,en/) and Endian ( but those are based on Linux. I trust security and maturity of BSD any day.

    The scan engines used for above mentioned requirements should be of reputable vendor with punctual & accurate updates. Content filter should be based on advanced content recognition by keyword beside the usual blacklist method.

  • Web url & content filter's and antivirus filter based on squid(or any proxy) must work by ICAP technology.
    In this time free projects on beginner state. I found many commercial, and low free projects (poesia for example - supported Euro-Union).
    AND squid-ICAP-client now not stable :(
