How secure is Identity-Based encryption?

Over the past several years, I was always taught to never create my own crypto algorithm. But now I'm looking into Voltage SecureMail (which does use identity-based encryption) and I think I'm way over my head in trying to figure out the quality of the system.

If you've used Voltage before, I'm looking to see how secure cryptosystems actually are (and Voltage particularly). I think I'm underqualified to fully know so any help on this would be greatly appreciated

    How secure is Identity-Based encryption?

    It is potentially as secure as the encryption algorithms used by the provider. I'm not aware that Voltage publishes the specific algorithms they use; at least, I didn't find a mention in web-site specifications nor in any reviews I saw. I did not do an exhaustive search.

    Various generally reliable sources seem satisfied with Voltage as far as security goes, though some point out that the same type of service is available for less cost and can provide more features.

    Without actual publication of algorithms, it is not possible to to give a definitive answer to "how secure" it is. If anyone knows a source for Voltage, a fairly direct assessment would be possible.
