Why use a VPN such as CryptoSeal Connect?
Whenever you connect to Internet servers using public wifi or other insecure networks, it's easy for people to monitor your traffic. If you're just browsing the news, no big deal, but if you are accessing and managing sensitive business servers, . SSL and ssh can help, but all it takes is one unencrypted connection to a network service for someone to steal passwords or other authenticatiovn credentials. Just monitoring your traffic may reveal business information about you or your clients which you may have a legal duty to protect.
If you travel internationally, or are involved in a high profile business or profession, you may be a target of directed attacks. Plus, do you really want every Internet service you use to know your location (based on IP) when you connect from any network?
VPNs also allow you to take sensitive servers entirely off the public Internet. Why should anyone who can steal a password have full access to your source code, or your internal accounting data, or an in-house mail server? A VPN also allows you to give limited access to contractors or vendors, managing it centrally, and is a "belt and suspenders" security solution in case a service is misconfigured, a user has weak passwords, or or a new vulnerability is found.
