LifeSize, a division of Logitech, said it ships all of its products with auto-answer disabled by default. Secure deployment remains a challenge with video conferencing systems, and the company is committed to simplifying the process, it said.

LifeSize said it offers a client-server NAT (Network Address Translation) traversal product called LifeSize Transit, which helps administrators set up conferencing behind the firewall with encryption. A cheaper option is LifeSize's Connections, which involves downloading a program to a computer. The cloud-based service allows for encrypted calling behind the firewall with a simplified setup process.

LifeSize is also doing more to try to educate its customers. On Tuesday, it launched the LifeSize Enablement Network, which is a series of short video training clips to educate its customers more about it products. That program was in development well before Rapid7's findings were publicized, according to a LifeSize spokeswoman.

But Moore feels overall teleconferencing systems should be made easier to securely deploy since they "are not very well understood by the technical people," he said.
