Sentinel Visualizer - 2026 Pricing, Features, Reviews & Alternatives

SentVi (formerly Sentinel Visualizer) is Windows-based link analysis and data visualization software built for intelligence analysts, law enforcement, investigators, litigation teams, fraud examiners, and researchers. It takes the data you already have in spreadsheets, databases, and case files and turns it into interactive link charts that reveal hidden relationships among people, organizations, phone numbers, accounts, vehicles, shipments, places, and events.

Import data from Microsoft Excel, CSV files, Access, or SQL Server. Start with a single entity and expand outward one degree at a time, or load thousands of records and let SentVi's automated layouts organize the network for you. Layouts include hierarchical, circular, force-directed, orthogonal, and incremental, with entities grouped by type. Search entities, relationships, and document content; build queries with the Dataset Builder; and filter by entity type, relationship type, or numeric ranges to reduce a crowded chart to what matters.

Analysis tools go beyond drawing. Shortest Path and All Paths show how two entities connect. Social Network Analysis metrics identify key influencers, cut-points, and cliques within a network, and entities can be colored and sized on a gradient by their metrics. Temporal analysis shows how a network changes over time, with timelines built from start and end dates on entities and relationships. Geospatial views plot entities with latitude and longitude on satellite, street, and hybrid maps, with Esri ArcGIS support and Google Earth integration, so investigators can see locations, movements, and patterns alongside the network. A 3D stereoscopic view is included for exploring large charts.

SentVi runs on your PC, your network server, or your cloud, and data is stored in Microsoft SQL Server, an industry-standard format you control. SentVi never sees or touches your data, and the software can run fully disconnected from the internet. SQL Server Express is included at no charge for single-user databases. Multi-User and Enterprise editions share a database across a team with user-by-user read, write, and view permissions for complete data security.

Share results without sharing licenses. Export charts and images for reports and presentations, or save a chart as an SVX file that colleagues open in the free SentVi Reader to view the network and drill down into the details behind it. With the concurrency option, licenses can be shared across unlimited computers, limited by the number of simultaneous users, with no dongle required.

SentVi is created by FMS, Inc., a US-based software company with more than three decades of experience and customers in more than 100 countries. Originally built for the intelligence community and an In-Q-Tel portfolio company, SentVi serves law enforcement, government, defense, legal, financial, and commercial customers worldwide. Available as a perpetual license with optional annual support, or as a monthly subscription. A free trial is available.
