LimaCharlie Custom Detection & Response Rules is a security operations platform that enables organizations to create custom detection logic for identifying malicious behavior specific to their environment. The platform provides the ability to design complex, organization-specific detections tailored to unique security requirements. The system supports both pre-made detection rules that can be subscribed to, as well as custom rule creation for specific organizational needs. It includes support for stateful detection types, allowing for more sophisticated detection scenarios that maintain context across multiple events. The platform delivers automated response capabilities with an average detection-to-response time of under 100 milliseconds on endpoints. This rapid response mechanism enables organizations to react quickly to identified threats. Users can craft detection rules using flexible logic to match their specific security strategy and use cases. The platform is designed to give security teams control over their detection and response workflows, allowing them to implement custom security logic beyond standard signature-based approaches.
