I can't access their website. However, I can access the website for Alliacense. I googled the address show for Alliacense and the following came up.

Voltage Security, Inc.
20400 Stevens Creek Boulevard
Suite 500
Cupertino, CA 95014
USA Tel: +1 (408) 886-3200
I called Voltage Security and was told they have occupied this suite since December. The receptionist said that they receive mail for TPL but they send it back to the post office. Was TPL using this same address? Was anyone aware that they have moved?

PTSC has admitted to moving its office, however, no public statement has been given as to the new location. Wonder what is going on with both companies.
