We have been extremely pleased with Sofie at A-1 Security. Not only did she come by and do a walk-around assessment of our house, she followed up several times to be sure we actually knew how to use it.
Their process is to assess the house for likely entry points and secure those. We didn't even think about it and would have had trips in all the wrong places.
We even have access from our phones to arm/disarm and get notifications of any faults. I know when the nanny takes the kids for a walk and returns back, or if I forgot to arm it when I left. I even disarm as I'm pulling up so I don't have to drop everything immediately when I walk in the house.
She (and they) do an amazing job, and they're local.
With our remote recorded cameras and bidirectional alarm systems, you will know if your children are coming home on time, whether they are doing homework or playing video games, and whether they are inviting friends into your home.
