About Prophet Security

Prophet Security sells Prophet Agentic AI SOC Platform, which automates the process of triaging, investigating and remediating security alerts. Prophet Security says security teams are buried in alerts, fragmented workflows, and tools that do not talk to each other. Prophet Security says it is building an AI SOC platform that brings reasoning, context, and consistency to every alert.[3][4]

Prophet AI spans autonomous alert investigation and response, continuous threat hunting, and closed-loop detection engineering. Prophet Security says Prophet AI agents work in unison across detection engineering, threat investigation and response, and threat hunting. Prophet AI investigates every alert with senior-analyst depth and delivers determinations that can be audited. Prophet AI responds through scoped Agent Actions, autonomously or with customer sign-off.[3][12]

For threat hunting, Prophet AI lets users ask any question of their environment in plain language to find hidden threats. Prophet AI researches emerging threats and provides the hunt, ready to run or schedule. For detection engineering, Prophet AI maps MITRE ATT&CK coverage from a customer's own investigations. Prophet AI ships tuned and net-new detections, backtested and ready for customer approval. Prophet Security offers human experts behind the AI, 24x7x365, with every malicious determination reviewed.[3]

Prophet AI automates high-volume tasks including alert triage, contextualization, false positive filtering, phishing analysis, IOC enrichment, incident response, and threat hunting. Prophet AI escalates cases to humans only when it detects a verified threat or a complex ambiguity requiring expert judgment. Prophet Security says Prophet AI auto-closes an alert with a detailed justification when the data proves an activity is benign. Prophet AI shows the logs, timestamps, or user actions it used to justify its finding, so customers can audit the logic.[6]

Prophet Security says it is built to be vendor-agnostic, integrating with an existing security stack rather than replacing it. Prophet Security connects via API to SIEMs including Crowdstrike NG-SIEM, Microsoft Sentinel, Cisco Splunk, Elastic, and Sumo Logic, to EDRs including CrowdStrike, Microsoft Defender, and SentinelOne, and to identity providers Okta and Microsoft Entra ID. Prophet Security supports webhooks for custom sources and bespoke business processes. Prophet Security supports bi-directional integration with SIEM and SOAR platforms, and Prophet AI can update the ticket or case management system with the results. Prophet Security says onboarding typically involves connecting API keys, after which the AI maps the customer's data schema.[6][15]

Prophet AI deploys as a dedicated single-tenant, with a bring your own key option and no training of AI models with personal data. Prophet Security says customers can run the data plane in their own VPC. Prophet Security says it can operate in a Human-in-the-Loop or Human-on-the-loop manner.
