I am looking for network security appliances for my office networks. I am having 70 computers connected in the network. I came across few company Sonicwall, WatchGuard, Cyberoam. Any suggestions guys?
I don’t know about other companies that you have mentioned, however I am using a product offered by WatchGurad i.e. network security appliance. It protects my network very well from various web threats.
Allow me to say, however, that a Cisco ASA is NOT something that you just plug into your network and forget about. It needs to be configured properly which should only be done by a CCNA/CCNP certified professional. A network of 70 computers would justify this cost. Whatever you do, don't be cheap. The worst thing you can do is buy a cheap firewall and wind up having your entire network penetrated. The other hardware firewalls are cheaper and easier to setup, but I guarantee you they're not nearly as good.
