Artemis Security

Artemis Security offers an AI-native security operations platform designed to replace or augment traditional SIEMs. The platform focuses on threat detection, investigation, and response across identity, cloud, endpoint, network, and SaaS environments.

Core capabilities include:

• Adaptive, environment-specific detection engineering that continuously generates and tunes detections based on the customer's unique infrastructure, users, and business context
• Autonomous threat investigation using AI agents that correlate signals across multiple log sources, trace attack chains, and produce complete case reports with timelines, evidence, and recommended response actions
• Threat intelligence automation that maps incoming threat reports to MITRE ATT&CK, identifies coverage gaps, and generates environment-specific detections within hours
• Natural language querying ("AI Mode") that allows analysts to investigate and explore security data without writing query syntax such as SPL, KQL, or SQL
• Federated data querying to avoid forced ingestion costs while maintaining broad visibility
• Environment intelligence that surfaces security posture issues, shadow IT/AI usage, and cost optimization opportunities

The platform targets enterprise security operations teams and positions itself as a full-lifecycle solution covering detection, correlation, investigation, response, and containment. It claims a 96% reduction in mean time to resolution compared to legacy tooling.

Customers referenced include organizations in financial services, technology, and insurance sectors. The platform integrates with existing security stacks and can function as a standalone SIEM replacement.
