International betting integrity body ESSA has announced PokerStars' sports betting brand BetStars as the latest operator to join the association.
The addition of BetStars takes ESSA's membership to 25 sports betting operators and follows that of 888sport, which became a member in January.
"Backed by Amaya, one of the world's largest gaming groups with 108 million registered customers, the addition of BetStars brings clear advantages for ESSA and its alert platform, whilst BetStars will benefit from access to a growing and effective operator run network focused on protecting its members' businesses from fraud," he said.
Zeno Osskó, Managing Director of BetStars, added: "BetStars is committed to keeping online betting fun and safe for our customers. The move to join ESSA underlines that approach and our determination to identify and tackle those that seek to manipulate sporting events against fellow consumers and responsible operators.
"We look forward to engaging closely with our partners within ESSA to maintain the integrity of sportsbook markets."
