What Security Information Systems does
Security Information Systems (SIS) is a privately-held Orlando, Florida-based software company that has built Alarm Center, an on-premises Windows/SQL alarm monitoring and integration platform, since 1987. The platform is purpose-built to centralize command and control across multi-site physical-security operations for federal, state, and local government agencies, educational institutions, critical infrastructure operators, and central monitoring stations, with more than 5,000 cumulative installations reported across 120 countries. Its core technical differentiator is the proprietary Universal Data Integration System (UDIS), which integrates signals from 85+ types of alarm receivers spanning multiple decades and manufacturers, backed by a library of 100+ third-party system integrations.
Alarm Center follows a modular architecture: the Monitoring & Dispatch Module is the required base, extended by optional add-ons including Video Integration, Sync Agent, Web Suite, Graphical Aid, Access Control System Integration, Billing, CAD Integration, Reporter, Service, Dealer Access, Print Catcher, and Custom Integration. The platform is certified under UL 1981, the Risk Management Framework (RMF), DoD ACAS, and SCCVI, and holds Authority to Operate on Department of Defense networks worldwide, with 99.99% claimed uptime for mission-critical deployments.
SIS operates a hybrid revenue model combining perpetual on-premises software licenses, recurring annual maintenance and support across three tiers (Office Hours, Emergency, and Platinum), and hourly-billed professional services including training, custom integrations, and dispatch-center setup. Since June 2019, SIS has operated as a wholly-owned subsidiary of EverCommerce (NASDAQ: EVCM), a SaaS platform serving more than 690,000 SMBs. The company goes to market primarily through direct enterprise field sales targeting federal, state, and local government customers, supplemented by a flagship reseller partnership with Carahsoft Technology Corp. formalized in June 2025 to broaden reach across federal, state, local, education, and healthcare procurement vehicles.
