I'm using Visnetic Firewall (from on all of my Windows
servers, and probably on all of my Windows clients pretty soon. One thing I
like from Visnetic is:
- It is just a packet filter. Doesn't do any application level filtering,
which is a good thing for a server. Who would keep watching the console of
the server for popup generated by a firewall asking "do you want to allow
this application to send packets to that destination"
- As far as I know, since it is simple, it hasn't had any security issues,
like Zone Alarm did, Kerio did, and the funniest one was Blackice, which was
exploited by witty worm. My principle is, a firewall suppose to protect the
system it's protecting. If a firewall since it is made quite complex, with
all kind of unnecessary features, then have some vulnerabilities in it, which
instead protecting its host now is threatening its host then what good does
it have?
- It is now configurable both by GUI and command line
- Has sequence number hardening and tarpit
