"If your company has people on the road, such as sales or technical people, a VPN is a good method for letting them access data on the company network. Many different VPN solutions can be bought, but many are free. Here, I discuss only solutions you can set up without buying a commercial VPN product. The main VPN solution used for more complex tasks is IPsec; some people use PPTP. Although PPTP is usable, security flaws have occurred in its past, and it simply does not match up to IPsec."
