Open Source Alternatives to Thinkst Canary

A deception-based security system that deploys decoy assets across a network to detect intruders. The product uses honeytokens and canary devices to alert security teams when unauthorized users interact with fake servers, files, or credentials. It is designed for security operations teams to identify breaches early by monitoring for activity on assets that have no legitimate business purpose. The system is deployed as a set of virtual or physical devices throughout an organization's infrastructure. By creating a layer of fake targets, the software helps administrators distinguish between normal network traffic and malicious activity. This approach allows organizations to receive high-fidelity alerts without the noise typically associated with traditional security monitoring tools. The software is used to protect corporate environments by providing a proactive way to catch attackers during the reconnaissance phase of a breach.
