Ask HN: Remote access, are you using a VPN?

This is more related to startups and small business, curious how some of you are working around network access to common git/repos/etc. Are you using a VPN to connect to your servers or work network? If not how do you manage access? I was skimming over https://news.ycombinator.com/item?id=6906979 and some of the answers made me question access to common work areas. Thanks.
