They don't have DMA checks at the moment, FW sellers (including cyber-ammo) usually advertise the fact that if you have money to spend, it would be a good idea to buy it, after all, you would already be prepared for the future, since compared to other mainstream anti-cheats, the first and smartest option would be to start detecting the most used options, which would be free firmware. Just make sure you are buying from a place with enough reputation in the DMA market, so you are paying for something that was actually made by the person selling it and not taken from a free place and resold as if it were made by that person (known as fake FW devs). The FW market is full of people like that.
It is always good to take precautions.
