What Fluency does
Fluency is an AI-native security information and event management (SIEM) platform that packages security operations — investigations, posture reviews, detection engineering, reporting, and service workflows — as callable capabilities rather than console-first workflows. The platform combines streaming analytics, behavioral case analysis, and a permission-aware operating layer (the Logic Layer and MCP server) that exposes functions to AI clients including Anthropic Claude (Co-Work and Code), OpenAI Codex, and ChatGPT. Role-specific skill packages (MSSP, CISO, Investigator) bundle reusable workflows and evidence-backed outputs for distinct personas, and the platform supports 134 configured data sources across 10 AWS regions.
The underlying technology distinguishes Fluency from legacy SIEMs by enforcing scope before action, separating read/local/write mutation tiers, and preserving source-record evidence attached to every AI-generated conclusion. Behavioral analytics cluster related activity into cases with timelines, enrichments, and MITRE ATT&CK mappings, while a fingerprint catalog and replay infrastructure support detection engineering. AI capability spans anomaly detection, natural-language querying, autonomous agent workflows, process automation, knowledge retrieval, and predictive analytics.
Fluency operates a dual GTM: a partner-first channel targeting MSSPs and MSPs with multi-tenant architecture and entry pricing as low as $30/month per tenant, alongside direct enterprise sales with transparent public pricing — asset-based ($10/user/month, $16/server/month, $200 minimum) and capacity-based ($2.99/GB, $118 minimum). Founded in 2013 and headquartered in Rockville, Maryland, Fluency is a privately held, bootstrapped company with 1–10 employees, serving customers across MSSPs, enterprise CISOs, SOC managers/analysts, and detection engineers.

Fluency product offering
Product offeringCore offering
Fluency sells an AI-native Security Information and Event Management (SIEM) platform that ingests streaming telemetry, performs behavioral analytics, and assembles evidence-backed cases. The platform exposes a headless operating layer (Logic Layer with MCP server) so analysts, MSSPs, CISOs, and AI clients such as Claude, Codex, and ChatGPT can run investigations, posture checks, reports, and detection workflows through permission-aware functions and role-specific packages without direct console access.
Product overview
Fluency is an AI-native SIEM platform built around reusable security operations rather than console-first workflows. The core platform (Fluency SIEM) combines streaming analytics, behavioral cases, analyst-ready workflows, and headless operating surfaces. The Logic Layer provides the permission-aware operating abstraction between AI clients and infrastructure, exposing operational intent through deterministic workflow logic, skills, and evidence stores. The MCP Server enables AI clients (Claude Co-Work, Claude Code, Codex, ChatGPT) to safely execute bounded security workflows. Role-specific packages (MSSP, CISO, Investigator) bundle skills and functions tailored to different operating surfaces. Pricing offers choice between Asset-based ($10/user, $16/server) and Capacity-based ($2.99/GB) models. The Partner Program enables MSPs and MSSPs to deliver Fluency's capabilities with multi-tenant architecture and dedicated client spaces.
