Are bespoke travel companies reliable when it comes to security?

Absolutely. A bespoke private travel company will ensure that you get the best experience from your trip,  and this will mean absolutely nothing if there is no optimal security. 

One of the things that such services offer is an extensive understanding of your destination. For this reason, they are able to properly devise a plan that makes sure that you are not only able to have fun everywhere you go, but you are able to do so safely while staying away from the less pleasant parts of your destination.

Another great thing about bespoke private travel is that it is flexible and it can include pretty much any kind of arrangement you want in your travel – as long as you can afford it. 

But of course, given the fact that these arrangements are usually suited for luxury travels worldwide, I doubt you will need extreme security measures in the first place.
