## Reactive Security Protocols

Reactive Security Protocols are systems designed to detect and respond to threats in real-time as they unfold on the blockchain. These protocols monitor transaction streams for suspicious patterns and trigger automated defenses, such as pausing contracts or limiting transaction volume.

Unlike proactive security, which focuses on code audits and bug prevention, reactive security acknowledges that vulnerabilities may exist and focuses on minimizing damage once they are triggered. In decentralized finance, this is a critical layer of defense against sophisticated exploits.

It often involves integration with decentralized monitoring networks that alert security teams to potential breaches. By automating the response, it significantly reduces the time between threat detection and mitigation.

This is an essential component of modern, resilient financial architecture.
