PROBLEM

Traditional tools can't handle cloud scale

Teams are stuck choosing between two broken approaches:

Knocklabs MCP

Built for the AI Security Era

Traditional SIEMs can't handle AI workloads. Queries are too slow and too expensive for AI agents to explore freely.

Knocklabs is the only platform with the speed and economics to make AI-driven security viable.

MCP UI
API-First Architecture

Every query, every dataset available programmatically

Built for integrations, automation, and custom workflows. Connect Knocklabs to your existing tools and security stack.

Native MCP Support

Fast access to your Security Data Lake with Model Context Protocol

AI agents get structured access to your security data through a standardized interface built for intelligence tools.

Built for AI Workloads

Fast and economical for AI to freely iterate

Enable investigations that would timeout or cost too much in traditional SIEMs. AI needs complete context, Knocklabs delivers it.

“We can search through a full year of logs in seconds, giving us visibility into an order of magnitude more data than before. Analysis at this kind of scale is essential in the cloud era.”
