In defence of the game, they do try to give justification for Cerberus' increase in strength between ME2 & ME3. The troops and resources come from Reaper tech, it's implied that most of their attacks are surgical strikes and that their forces are generally smaller than they appear. It's suggested that the garrison on Eden Prime were hiding their numbers and once that was revealed, they got kicked off the colony quite easily. Shepard states in his interview with Allers after the Citadel attack that they basically exhausted their forces trying to take down the Council, though that doesn't really hold water if you do the Cerberus Scientists mission right afterward where it looks like someone kicked a hornets nest towards the end.
The reason for the increase in troops was explained by Sanctuary, but where they get all the ships, armour and equipment is never alluded to. Considering how expensive Project Lazarus and the Normandy SR2 would have been, it's clear they do have some pretty serious funding in their pocket. Presumably they could make back quite a lot of money from those projects; it's not unreasonable to suggest an organisation that created a procedure to cure the dead would be pretty loaded with investor money.
It's also possible that they got all their manufacturing technology by swiping what the Reapers leave behind, since the Reapers don't need fuel or factories. The Reapers harvest a colony, leave the resources behind for their helpful little minions to use, Cerberus swoops in and claims the goods like a bunch of white and gold vultures. The Illusive Man would justify this as pulling a fast one over his enemy, then go back to clutching at his temples and groaning.
