Nowadays many large companies have outsourced their development to offshore. Almost all large organizations I've worked with has a large number of developers in India. One common issue is how to let them access to our SCM system?
Many use VPN, but have concerns, because these developers has nothing to do with our organization, e.g. we outsource to IBM, IBM gives it to India, and so on. There are concerns to let these developers come into our WAN/LAN directly from VPN.
I've worked with ClearCase and RTC, as well as MS TFS, and I also put a couple of posts here to discuss this issue. https://jazz.net/forum/questions/90147/rtc-offshore-access
I am just wondering how you guys are handling this issue and what product/solution works best for you.
