What is Lost When Armor Protection Trial Expires

My Armor trial expires in about a week. What will I lose when this trial expires? Specifically, without an active subscription, will I continue to get alerts when new devices connect to my network?

I am not too concerned about my "score" as it seems to be on a sine wave - 83, then down to 62, then back to 83, then 62. Has repeated the pattern every few days with no changes to the network, and no real explanation on what it takes to get (or keep) a good score.

Likewise, in almost 30 days since the trial started, I have received one notification that a malicious URL was blocked. No idea of how the URL was triggered (it was not a direct link I wanted to follow), or when the block occurred. Only that a link was blocked on Machine X.

I have tried calling Netgear, twice, and have spent over two hours on the phone and none of the three reps I spoke to have had any idea about what I was asking.

Any insights on the above would be much appreciated. Thanks!
