THE SAFEST PLACE TO MEET IS THE ONE PEOPLE TRUST.

Cinder protects users in the interactions where they're most vulnerable. Stop scams, harassment, and predatory behavior before they drive people off your platform.

  • Policy enforcement

    Enforce community standards across messages, profiles, and posts. Agents trained on your policies handle volume automatically and escalate the cases that need a human.

  • Phishing and scam prevention

    Detect romance scams, financial manipulation, and phishing attempts in messages and profiles before your users are harmed. Trained on the patterns specific to your platform.

  • Harassment and abuse detection

    Identify coordinated harassment, repeat offenders, and emerging toxic behavior patterns before they escalate. Surface the full account history so reviewers see the context, not just the latest report.

  • DIY workflow builder

    Build, test, and deploy review workflows without engineering support. Route signals by content type, severity, or user history and get the right work to the right reviewer every time.

Cinder provided rigorous adversarial testing that matched our release velocity. Their team found important edge cases and helped us address them before launch.
