Acquisition Opportunity Apex3 Systems was acquired by DSI Security Services in September 2025, creating a potential cross-sell path for DSI to leverage Apex3’s security integration expertise in new markets and existing DSI client bases.

Security Expertise Specialization in security consulting, IP camera systems, video analytics, access control, and secure network topology positions Apex3 to address comprehensive physical security modernization projects for mid-sized campuses and multi-building properties.

Mid-market Focus Headquartered in Illinois with 11-50 employees and annual revenue in the low seven figures to mid eight figures range, Apex3 embodies a scalable but nimble partner ideal for managed services, recurring maintenance, and turnkey security system refresh engagements.

Technology Stack Utilizes a pragmatic tech stack (MySQL, UI libraries, analytics and engagement tools) that supports integration-heavy projects, suggesting opportunities for expanding managed services around data analytics, monitoring, and secure access governance.

Growth Readiness Recent acquisition signals momentum and potential for expanded capabilities; sales conversations can explore bundled security solutions, hybrid cloud or on-premise deployments, and expansion into adjacent markets through DSI’s network.
