Base Filtering Engine is needed for some functions (HTTP scanning) of ESET NOD32 Antivirtus, and it will complain about it not being available if it is disabled. This service is also needed for proper functionality of ZoneAlarm v9.2.x (free).

Windows 8

Stopping or disabling the BFE service will significantly reduce the security of the system. It will also result in unpredictable behavior in IPsec management and firewall applications.

Additional Information

If you use an external hardware firewall/gateway/router between your computer and the internet, do not use IPsec (VPN tunneling, etc) and Internet Connection Sharing (ICS), then this service and the following group of services can be disabled:

I highly recommend that you do not disable the Windows Firewall unless you use a different software firewall or external hardware solution, but the services listed above are all involved with each other.
