Composica 4.0 is available as both an on-demand solution (ASP/SaaS) hosted on our servers, or as an installed solution on the customer's servers. 

The installed solution is ideal for customers such as banks, government departments, and other large organizations, which often disallow Internet access for security reasons. The hosted solution is ideal for small to medium size businesses. 

Note that both of these deployment options offer the exact same set of features.
