St. Louis IT and Cybersecurity Company
Inzo Technologies® is a St. Louis IT company headquartered in Chesterfield, in St. Louis County. Since 1989, first as STL Communications, we have helped St. Louis organizations reduce technology risk and run more reliably, with managed IT, cybersecurity, business phone systems and healthcare technology from one team that owns the outcome.
IT, cybersecurity and phone systems from one St. Louis team
Most St. Louis businesses end up with separate vendors for IT support, security, phones and specialized systems, and nobody owns the gaps between them. We bring them under one team: managed IT and cybersecurity, a cybersecurity risk assessment to show where you stand, business phone systems including cloud voice and Avaya support, and healthcare technology and system integration such as West-Com nurse call, access control and wander management.
Managed IT and cybersecurity services for St. Louis businesses
Five connected service layers plus the risk assessment we use to find and prioritize what to fix, all run by one local team.
Managed IT Support
Keep your team productive and your systems running with support that has no hourly or block-hour charges, proactive monitoring, and vendor coordination.
Managed Network Services
Managed firewalls, switches, wireless, and network monitoring across every site, device, and remote worker.
Cybersecurity Services
Layered defenses across devices, accounts, email, and web activity that stop threats before they reach your business.
Security Operations & Monitoring
A U.S.-based Security Operations Center (SOC) that monitors your environment and responds to threats it detects.
Data Protection & Recovery
Verified backups and tested recovery, including Microsoft 365, so ransomware or hardware failure does not become a crisis.
Cybersecurity Risk Assessment
Identify security gaps, understand your exposure, and prioritize the improvements that will reduce risk across your environment.

Managed IT support is a monthly agreement with no hourly or block-hour charges. The price depends on what is in scope, so we work through it with you in a 15-minute Insight Session. Whoever you talk to, get a written list of what the monthly price covers and what costs extra.
Hold every provider to the same written requirements: what the monthly price covers, who responds when work stops, who owns security and backups, and how you leave with your accounts and documentation. Our guide on how to compare IT service providers walks through each step.
