Fluency vs. Splunk Enterprise Security

Splunk’s brand is iconic in cybersecurity and observability. But its strength as a log search engine has also become its ceiling. It was built for a world where storing and querying large datasets was the hard part. Today, that problem has shifted—we now need real-time decision-making, not better archives.

The Cisco acquisition, in that context, highlights a tension. Cisco is focused on consolidating and integrating its stack. That’s not a bad strategy—but it’s a slow one. It puts Splunk in a defensive posture during a time when the market is being redefined by AI-driven detection, autonomous response, and streaming-first architectures. In contrast, newer or more focused vendors like Fluency can move faster and design around these new capabilities from the ground up.

🧠 Logs Aren’t Enough—Detection Requires Process

Splunk is an excellent log collector and search engine. But it wasn't built for real-time threat detection or autonomous workflows. Fluency, by contrast, is a full-process system that handles alert evaluation, scoping, response, and review using live data and intelligent logic.

Splunk’s Limitations as a Detection System

Query-based detection introduces lag and misses live context
Expensive index/search cycles discourage high-fidelity detection
No native AI workflows for triage, response, or remediation
Heavy reliance on SOAR for post-alert handling
Rules must be manually tuned and maintained without feedback loops

Fluency’s AI-Driven Detection Engine

Fluency isn’t just a destination for logs—it’s a system that reacts. Every alert is evaluated in context, enriched with history, and handled by AI workflows that perform or recommend action in real time.

Streaming-first architecture—no search delay, no polling
Structured AI workflows from validation through remediation
Integrated MCP support for memory, state, and context handling
Actions are executed directly—not just recommended
Reduced need for SOAR thanks to native automation and logic

⚙️ Search vs. Stream: Two Detection Mindsets

Splunk treats detection as a saved search problem: find events after they happen. Fluency treats detection as an ongoing process—evaluating state and behavior as data flows through the system.

Splunk's Search-Centric Model

Detection is done by scheduled queries or dashboards
No awareness of prior events or behavioral chains
Alert floods require external tooling to manage
Custom rule logic must be hand-built in SPL

Fluency’s Process-Aware System

Logic executes inline—evaluating and responding in real time
Tracks memory and thresholds across behavior streams
FPL makes rule logic reusable and auditable
Handles scoping and ticket closure automatically
