VShell Server is a secure alternative to Telnet and FTP that gives you the strong encryption, trusted authentication, and data integrity you need to securely access network resources and transfer data. It is simple to install and set up, enabling you to quickly deploy and fine tune your server environment to comply with internal policies and external regulations. Its extensive configuration options and trusted authentication methods give you the right balance between protecting your network and providing your employees and customers with access to the data they need. Access control lists (ACLs) and virtual directory structures enforce your security policy, while "triggers" initiates protective or corrective measures if it looks like a security problem is developing.
