fwiw: don't agree to anything based on claims companies or people make to you. Especially for security services. Take the information & claims they make & try to do your research as to the information being valid. Sounds like you're a skeptical person already, thats good.
one note is; it appears Comcast securty uses (poss requires) a Comcast internet (internet/phone?) modem for service & alarm monitoring over (via) the internet. If internet goes down so does Alarm monitoring & reporting. If someone cuts the internet cable outside the house, again no Alarm monitoring & reporting.
Established & long time trusted security companies offer choices in methods of Alarm monitoring & reporting that are less vulnerable.
So make choices using Informed-judgement :)
