[Kingsman] Why do the Kingsman not have a way to make sure failed candidates don't expose their existence.

So in Kingsman: the Golden Circle a former candidate for Kingsman, Charlie, gets the group wiped out by telling the main villain about their existence.    The fact that the group doesn't have any way to stop previous candidates from revealing them seems like a major security risk.  The whole reason Charlie failed to become a Kingsman was that he didn't pass the test to not give them up, so they even knew he couldn't be trusted.  With all the technology and resources they have, how does the Kingsman not have a way to prevent someone like Charlie from talking about them.

We had ways, back when Maggie was in charge and this whole outfit ran ship-shape.  If you didn't pass the tests, they were fatal, and that was that.  Wrote something up about a training accident for the families, small obituary in the papers, then brandy and cigars in the sitting room.
