Roblox Releases Early Warning System to Help Keep Children Safer Online

SAN MATEO, Calif.--(BUSINESS WIRE)--Roblox Corporation (NYSE: RBLX), an immersive gaming and creation platform, today announced Roblox Sentinel, an artificial intelligence (AI) system that helps detect child endangerment communications early so Roblox can investigate instances sooner and flag to law enforcement when needed. Sentinel is open source and available for other digital platforms across the industry to utilize.

As part of Roblox’s open-source safety toolkit, Sentinel is an early-warning system designed to identify subtle, hard-to-detect communication patterns that could indicate potential grooming. Since late 2024, Sentinel has been helping Roblox take prompt action and investigate to help keep users safer. In the first half of 2025, Sentinel aided our team in submitting approximately 1,200 reports of potential child exploitation attempts to the National Center for Missing and Exploited Children.

“AI has become foundational to how Roblox approaches safety, and how we help keep our users safe,” said Matt Kaufman, Chief Safety Officer at Roblox. “Contributing to the open-source community is key to our approach to online safety as we know these challenges exist across the digital world. We aim to share our technologies and collaborate with other leaders to make the internet a safer place.”

A strategic blend of experienced humans and AI is imperative in scaling safety on Roblox, including detecting potential signals identified by Sentinel. Expert analysts review cases that the AI system flags as potentially violative. The analysts’ decisions create a cycle that allows Roblox to continuously tailor and refine the examples, indexes, and training sets. This process with humans is vital in helping Sentinel adjust and stay up to date with new and developing patterns of bad actors.

Roblox works to improve safety across the industry wherever possible by open-sourcing innovative technical solutions, as well as collaborating with partners including ROOST, in which Roblox is a founding partner, and the Tech Coalition’s Lantern project.

“Too many platforms today lack access to the sophisticated tools needed to identify and prevent online harms, particularly those targeting children,” said Juliet Shen, ROOST Head of Product. “At ROOST, we believe that robust safety protections should be accessible to anyone committed to protecting their users, and we’re so excited that Roblox is contributing more openly available tools to the trust and safety space.”
