I have felt for decades that Mistress Lori's tubes / cages are the most secure on the market. They require a piercing and are expensive and so I would target that for the long run.
Anything leather is a toy.
Many that are plastic or silicone are toys.
There is much debate about scrotum anchored devices being toys. IMHO you can't put handcuffs on an octopus tentacle. An unachored penis will find it's way out of a tube or cage.
So that leaves piercing, pluging, and tethering.
Tethering products have not come into the market very much and have not attracted much attention. But it does have some promise.
Plugging is scrotum anchoring with an added rod or tube that extends inside the urethra to (or close to) the scrotum ring. This could have some health issues in regard to bladder infection and trauma for active folks.
Piercing of some form is the commonly accepted secure means. It will take a while for healing and stretching to achieve a size to support a steel device. So begin thonking about this and how serious you are about chastity now.
Take Lori's advice and start with an inexpensive scrotum anchored device to see if the chastity device lifestyle will work for you.

Your request about plugging, was that a urethra or a butt plug. If the latter, IMHO, it should be thought of seperately. There are devices that have butt plugs attached. But due to anatomy differences from man to man I doubt one could find one that would be flexible enough to be comfortable long term.
One could fashion an acceptable solution by simply cabling a plug to the device. The plug would then be in place or produce an ominous bulge in public.
