LMI is plenty secure if you use good passwords. With all the technology available, good passwords with a minimum of 8 characters, alphanumeric with one capital letter and a number INSIDE the password is strong. As the administrator, the passwords should be made by you in an acromyn or similar and no staff member should make their own password.
LMI Pro is not only legal, the benefits are worth it. If I were using Microsoft with Server 2008 or better, I would use RWA or RDP, which is a no brainer.
