Alfasentinel builds commercial security infrastructure for the modern API and AI stack. Our products — ApiSentinel and AgentSentinel — monitor production systems in real time, detecting behavioral anomalies that signature-based tools miss. ApiSentinel protects API surfaces against BOLA, brute force, rate spike, and shadow API attacks. AgentSentinel monitors LLM-powered agents for prompt injection, jailbreaks, PII leakage, cost spikes, and runaway loops. Both products are production-ready, self-hosted capable, and free to start.
