The suspension came into effect on 20 July, with the company currently forbidden from offering its services to UK players.
The list of its suspended online casinos includes casinoplanet.com, genesiscasino.com and vegashero.com, although Genesis Global believes this disciplinary action is "not only disproportionate but also inconsistent."
In a statement sent to Gambling Insider, the brand said: "Following the latest assessment, the GC decided to review Genesis’s British Remote Operating licence. In addition, a decision was taken by them to temporarily suspend this same license.
"Genesis has since taken independent legal advice and is of the opinion that the decision to suspend their operating license is not only disproportionate but also inconsistent with the GC’s previous regulatory enforcement action in regard to other operators. As a result, Genesis has confirmed that they will therefore be vigorously appealing against the decision to suspend using all channels open to it.
"In parallel, Genesis will fully cooperate with the GC in its license review and has already taken the initiative to voluntarily provide the regulator with an action plan following the assessment, prior to the suspension and review decision. Genesis has expressed their extreme level of disappointed with this determination and outcome and is therefore firmly committed to complying with the GC’s extensive range of regulations."
