I would use a Hardware Firewall.
We use Panda ( http://www.pandasecurity.com/usa/enterprise/solutions/gatedefender-performa/ )

Hello
I agree with awawada regarding hardware firewall
Basically it depends on your network scale, how many users exists, internet bandwidth, if VPN exist etc

We use Fortigate, is suggested for larger networks than Panda can hold

Agree with the others that a hardware-based firewall is the way to go.

I'd suggest evaluating your needs and the available funds. A firewall in general will keep out the bad guys and also filter, if you want, outgoing traffic to keep things more under control on the inside.

Remember that security should be a multi-layered approach. For example in my environment, we have AV protection on the desktops, we have a hardware-based firewall, an IDS/IPS device, email filtering and web filtering. Most of these are separate devices and/or services. We are currently looking to upgrade our firewall and the new one will have IDS/IPS built in. Once that's up, we'll be moving away from our current solution for that.

We've used Cisco PIX devices in the past and have found them to be very configurable and robust. Cisco no longer makes them and we are now looking at the Cisco ASA device.  Juniper also makes a nice hardware-based firewall, but I have no direct knowledge of them.

I can't speak to Fortigate as I've never used that.  However, in general terms, beyond what you've mentioned look at features - does it do what I need it to do and support - can I get the contract that I need at a price I can afford.
