Fluency Security AI-centric security operations

The Unbounded SIEM

Exceptional investigation. The whole security program beyond it.

UEBA, clustering, fault-tolerant risk scoring, and AI swarm investigation help Fluency cut through noise and close cases efficiently. Fluency Companion extends that same intelligence across the entire environment: find weaknesses, measure platform and data health, assess certification evidence, forecast capacity and cost, and guide the operating plan through a permission-aware MCP interface.

The Unbounded advantage

The agent knows what you mean. MCP teaches it how to use Fluency.

How an agent uses Fluency through MCPThe user asks an agentic AI a security question. Fluency MCP supplies operating knowledge, governed functions, tenant scope, and evidence rules so the agent can use Fluency SIEM to analyze, forecast, compare, investigate, assess posture, and create reports.YOUYOUR AGENTUnderstands intentFLUENCY MCPTeaches the agenthow to use FluencyFLUENCY SIEMDATA + ANALYTICSCAPABILITIESHealth + postureCertificationInvestigationForecastCompareReports + plansASKINTENTGOVERNED USEEVIDENCE + RESULTS RETURN

For MSSPs, CISOs, and CIOs

Turn exceptional investigation into a complete security service.

Turn security telemetry into an ongoing advisory service. Show where the environment is weak, what changed, whether controls and evidence support certification goals, and what the organization should improve next.

Analyze

What does the whole environment tell us?

Examine health, coverage, assets, vulnerabilities, controls, usage, and cases together to identify weaknesses and explain what matters.

Forecast

Where does this lead if nothing changes?

Project capacity, workload, cost, and risk from the evidence already in Fluency, with assumptions leaders can inspect and revisit.

Compare

What changed, where, and why?

Compare tenants, environments, teams, and time periods to reveal meaningful differences and direct the next operating decision.

Give the CISO or CIO a defensible operating plan: which gaps to address, where to invest, what to monitor, 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.

The SIEM foundation

Cut through the noise. Investigate with the full picture.

Fluency is built to excel at investigation. It organizes security activity before AI spends tokens on it, giving analysts and swarm workflows the correlated context needed to reach defensible closure efficiently.

Detect behavioral change

User and entity behavior analytics (UEBA) and correlation connect identity, endpoint, email, and cloud activity to reveal changes that deserve attention.

Cluster related activity

Clustering brings related signals into meaningful cases, reducing the number of separate alerts an analyst needs to investigate.

Investigate with AI swarms

Specialized AI work can follow the evidence in parallel, while risk scores, timelines, and source records keep the conclusion focused and reviewable.

Fluency Companion + MCP

One governed interface to the whole security operation.

Fluency Companion gives Claude and Codex permission-aware tools, context, and operational guidance—not only for investigations, but for health, posture, certification evidence, onboarding, reporting, billing, detection engineering, and planning.

Inside Fluency Companion

One exceptional investigation. One part of a larger system.

Companion brings correlated evidence, behavioral context, risk, and the next action into one working view. The same governed interface supports health reviews, certification evidence, weakness analysis, reporting, and operating plans without rebuilding the context.

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?
