I had a Viper alarm with these features installed in my car back in 2012 and immediately noticed that while their iOS app used SSL to talk to the API, it never actually validated the certificate, and was trivial to set up a man-in-the-middle proxy to grab a user's auth token and make requests as them. According to their reply their devs weren't able to replicate it, which told me all I needed to know about their ability to write secure software. It's good to hear they responded quickly in this instance, but I'm not sure I'd ever trust their devices again.
