Common reasons to contact us
The free tier covers 1,000 requests/hour (~720K/month) with no card and no expiry. Growth (€49/mo founding price) raises that to 5,000 requests/hour, and Enterprise adds custom volume pricing, SLA guarantees, dedicated IP ranges, and on-call support.
Our security engineers can help you design the right integration pattern for your stack — whether that's server-side API calls, the JavaScript SDK, or webhook-based alerting.
Responsible disclosure, partnership inquiries, or questions about specific detection signals. See our responsible disclosure policy for vulnerability reporting.
Sentinel is built and operated by a small team of security engineers focused exclusively on fraud and bot detection. We don't outsource support — when you email us, you get an engineer who has read your integration logs.
