Fluency vs. Google Chronicle

Comparing a streaming SIEM with built-in AI workflows vs. a Google-scale log lake. Speed and intelligence aren’t the same thing.

🤖 Where Is Chronicle’s AI?

To be fair, Chronicle is leveraging AI within its rule engine to help craft better detections. But there’s no operational AI responsible for investigating or responding to alerts. Because Chronicle does not reduce the volume of events and alerts, performing atomic AI analysis on each would likely be cost-prohibitive. The result is a system that enriches but does not act—a stark contrast to Fluency, where AI plays an active, decision-making role in the SOC.

Chronicle’s AI Gaps

  • No public implementation of ISO 42001 guardrails
  • No use of MCP or interoperable AI standards
  • Detection limited to predefined rule logic and enrichment
  • No user-definable workflows or streaming memory
  • AI is passive—never executes decisions or closes issues

Fluency’s AI Design and Execution

  • Streaming Multi-Context Processing (MCP) engine
  • Analyst workflows built into the system (Validate → Scope → Respond → Review)
  • AI closes and annotates tickets automatically
  • FPL enables behavior-level analysis with memory and feedback
  • Real-time detection with analyst-level response

🧠 Log Lake or Live System?

Chronicle excels at storing, indexing, and correlating logs at scale. But detection happens after the fact. Fluency processes events in real time—building context and triggering responses the moment events arrive.

Chronicle’s Retrospective Design

  • Focused on ingestion and search—not streaming analysis
  • Events processed after landing, not during transit
  • Detection relies on rules and correlation, not stateful logic
  • AI assists threat hunting, but not detection or response
  • No support for inline automation or memory-aware processes

Fluency’s Real-Time Philosophy

  • Inline streaming analysis with memory
  • Detections are part of live workflows, not queries
  • Uses context chains and process memory, not one-time matches
  • Behavioral tracking, anomaly detection, and response are built-in
  • FPL transforms alerts into actions—at speed
