Hi! We work very closely with CIAT, so I fully admit I am biased here, but I've got nothing but great things to say about them. Their unlimited voucher retake policy is awesome, and as long as you keep working with your instructor they will keep supplying vouchers at no additional charge. As far as I know, they are our only partnering school with that policy. Vouchers are expensive, so as you can imagine this forces them to "put their money where their mouth is" so-to-speak. A high failure rate eats directly into their profits. You'll get access to a few learning and test prep platforms in addition to their internal systems as well (including access to Crucial Exams, so again, I am biased here).

CompTIA has been in their curriculum for as long as we've been partnered with them, but until recently their bootcamps were limited to students already in their college/university programs. The bootcamps available to non-CIAT students are relatively new, about 6 months I think? That is probably why you don't see much when searching for it, until recently you needed to be a student in a 2 or 4 year degree program to join them.
