About Prophet Security

Prophet Security pioneers Agentic AI to automate security operations, shifting cybersecurity power dynamics to favor defenders. You will build an AI SOC Platform that triages, investigates, and responds to over 1 million security alerts. This saves an estimated 360,000 hours of manual investigation time for customers like Docker and Fortune 500 companies. Our platform reduces mean time to respond by 10x and decreases false positives by 96%. We recently raised $41 million in funding, including a $30 million Series A led by Accel.
