Thanks very much.... we're looking a series of models currently and all
the feedback I've received so far has been extremely helpful...

Best regards!

I've been using both these boxes for a while, the SSGs in particular,  
so I'll chime in.

Eric is right, the WebUI for ScreenOS is not very good, but it's far  
better than any of the interfaces I've seen on any other security  
devices. It has its quirks, but it does get the job done.

I have no complaints about the SSG hardware, you get decent port  
density across the line and 90% of the functionality you will want is  
there out of the box with no additional licensing required (stateful  
firewall, IPSec, all routing protocols, etc). Don't bother with the  
Antivirus and Antispam on ScreenOS, it sucks and Juniper knows it. The  
web filtering works pretty well, though.

They're very flexible with regards to interoperability with other  
vendors (even Cisco). I've connected one to just about every vendor  
imaginable and there is always a way to make it work.

If you're looking for a cheap router/firewall/VPN box, then the SSGs  
from Juniper are the way to go right now. JunOS Enhanced Services  
could make our lives even better too...

What he said -- with the J series you get JunOS and now JunOS Enhanced  
Services, so you get a full-fledged firewall as well. No need to  
convert them to ScreenOS (unless you need a feature that hasn't been  
ported from ScreenOS to JunOS ES yet). The only thing I really don't  
like in the J series is the lack of a non rack mount form factor. A  
lot of small and branch offices don't necessarily have racks and it  
can be cumbersome to convince someone they need a 19" wide noisebox to  
be their router.
