## What is RedELK?

RedELK is a specialized SIEM (Security Information and Event Management) tool designed specifically for red team operations. The tool focuses on monitoring and detecting blue team defensive activities during penetration testing and red team engagements.

The platform provides alerting capabilities to notify red team operators when their activities may have been detected by defensive security measures. This allows red teams to adjust their tactics and maintain operational security during long-term engagements.

RedELK enhances the usability of red team operations by providing visibility into defensive responses and potential detection events. The tool helps red team operators understand when their presence may have been discovered, enabling them to modify their approach or take evasive actions.

The system is built to support extended red team campaigns where maintaining stealth and avoiding detection is critical to the success of the engagement. It serves as an early warning system for red team operators working in environments with active blue team monitoring.
