Leased Lines v. VPN
Posted on 2005-04-15
Our company currently leases T1 lines from our main office to every remote office, 12 in total. We have one location that VPNs in using 3com hardware. The powers that be see that the office that VPNs in are able to do everything (well almost) that the leased line offices can do, at a fraction of the cost. I now need to give reasons why we should or should not move everything to VPN solution.
This is what I have so far.
Cost – VPN’s are less expensive that leased lines
Scalability – Access where you may not be able to get a leased line
Less expensive equipment
Slower speeds – users less productive
Security - as with any vpn solution, you are opening doorways into the network.
Inconsistent remote access performance due to changes in Internet connectivity
No entrance into the network if the Internet connection is broken
I would like someone that is experienced with VPN to give me a rundown of the pros and cons of moving everything to a vpn solution. Has anybody tried this and had it blow up on them? Has anybody tried this and have it work great?
I myself have limited experience with VPN in a coorporate envrionment.
What should my security conserns be? I am sure I will need to purchase new equipment to make this work both reliably and secure.
I currently use ISA server 2004 and a 3Com firewalls.
Thanks for all comments.
