Detect behavioral change
User and entity behavior analytics (UEBA) and correlation connect identity, endpoint, email, and cloud activity to reveal changes that deserve attention.
Fluency Security AI-centric security operations
The Unbounded SIEM
Prioritized cases. Evidence-backed answers. A clearer plan.
Fluency is an AI-centric SIEM that turns security activity into decisions your team can act on. Behavioral analytics, correlation, clustering, and risk scoring provide the foundation. Claude and Codex extend that understanding into investigations, operational planning, and certification readiness through Fluency’s MCP server.

The SIEM foundation
Fewer cases. Clearer priorities. Evidence behind every answer.
Effective AI starts with a SIEM that understands security activity. Fluency brings related events together so analysts and agents can investigate with context.
Cluster related activity
Clustering brings related signals into meaningful cases, reducing the number of separate alerts an analyst needs to investigate.
Prioritize with risk scoring
Risk scores help teams focus on critical cases. Timelines and source evidence support the investigation and the decision about what to do next.
For the manager
Analyze, forecast, and compare your security operation.
Go beyond closing cases. Examine system health, throughput, usage, billing, and coverage gaps to understand what is happening, what comes next, and what needs to change.
Forecast
Where does this land if nothing changes?
Project capacity and cost from usage and throughput trends. See the assumptions behind the forecast and revisit them as conditions change.
Compare
Is this worse than last time, and why?
Compare environments and periods to understand changes in coverage, workload, and performance. Identify where the team needs to focus next.
Analyze
What does this actually mean?
Examine cases, system health, usage, and billing with the underlying evidence. Explain the gaps and turn the findings into practical next actions.
Bring the findings into your operating plan: decide which gaps to address, where to invest, and how to measure improvement.
Evidence and certification readiness
Understand what your evidence actually supports.
Fluency analyzes available security evidence and documented processes to help teams assess readiness, identify gaps, and prioritize the work needed to close them.
Assess the evidence
Distinguish controls supported by evidence from those partially supported or not yet demonstrated. Keep the basis and limits of each finding visible.
Plan the next action
Identify missing telemetry, incomplete evidence, and process gaps. Turn the assessment into a prioritized remediation plan that teams can review.
Complement your compliance platform
Use the operational analysis alongside platforms such as Vanta and Drata. Fluency supports certification readiness; certification decisions remain with the assessor.
AI access through MCP
Give Claude and Codex the context to do the work.
Fluency’s Model Context Protocol server supplies tools, context, and operational guidance. It helps agents select capabilities, combine them into workflows, and interpret results within the user’s permissions and customer scope.

Inside Fluency Companion
One case. Twelve events. One decision.
Companion brings correlated evidence, behavioral context, risk, and the next action into one working view. Analysts can inspect the case, then carry the investigation into Claude without rebuilding the context.
Product screenshots use the Expo demonstration tenant with synthetic identities and intentionally unhealthy posture.
The company behind the product
A team that helps you put security intelligence to work.
Fluency combines its SIEM with hands-on deployment and ongoing support. We help customers overcome integration obstacles, establish useful workflows, and build operational capability.
Deploy with a practical plan
Agree on the first sources, access requirements, and questions to answer. Verify data flow and usable results as onboarding progresses.
Operate across customers
For MSSPs, multi-tenant workflows support customer onboarding, health reviews, investigations, and reporting within the appropriate customer scope.
Keep improving with support
Work with a team that understands the product and the operational obstacles. Fluency was recognized for Best Support in G2’s Fall 2026 reports.
Watch the story
See what it means to be Unbounded.
See how Fluency evolved beyond the limits of SaaS SIEM and gives security leaders access not just to data, but to knowledge.
The Unbounded SIEM
Free AI from SIEM API Ignorance
See why AI needs governed access to SIEM knowledge—not another brittle API integration—and how Fluency makes that operating model practical.
Behavioral AI Triage
Stop Sending Every SIEM Alert to AI—Use UEBA Clusters Instead
See how behavior clusters give AI the correlated context it needs to investigate meaningful activity instead of processing isolated alerts one at a time.
Operational modes
Install the operating model, not another prompt box.
Fluency packages skills, functions, and MCP server wiring so agentic clients can run safe operational workflows without exposing raw Fluency APIs. The MCP server remains the deterministic logic layer; the client routes, composes, and presents.
Ask questions no one dared to ask before, never mind dared to answer. Which tenants are unhealthy? Which signatures need ATT&CK mapping? Which customer has hidden operational risk?
