Yes, they are. This is because all Quickfire games are actually from Microgaming, and its smaller studios. Microgaming and, by extension, Quickfire are licensed and regulated by a number of top gaming jurisdictions. This means that the games have to be audited regularly to ensure the RNGs operating the game are running fairly. The games always pass these tests too, so you can rest easy knowing you're getting a fair gaming experience when you play these games at online casinos.
