Which one company technology is better to secure your network? Juniper , CISCO or Hawaii?

I prefer Juniper SRX Because it has more security features than CISCO PIX or ASA.Checkpoint and palo alto also good feature base and better security products currently available in market. But expense is too high on these products 

I partially agree on that but you need to look at the technical part, for example Cisco provides unmatched support globally while Juniper products are highly efficient, Sonicwall is easy to administer, Sophos provides more functionality as UTM.

you need to define what you are looking for in the first place 

i think Cisco & microsoft is big and largest in the world

Palo Alto Devices, Provides you a good sight of what inbound and outbound traffic.If you are looking for URL filters i better prefer cloud solutions like Zscaler.

I think every one has choice to get better product from market but its depends one your employer because he can purchase cheapest or highest price product. Cisco & Hawaii products easily available in the world wide and its support & service is better than juniper. Juniper is high class product manufacturer in the filed of of IT and i think its support & services are not available in world wide. So, in my point of view & experience Cisco & Hawaii is better than other firewall & IT equipment's.
