Managed IT Services for Ontario Businesses

Ontario is one of the busiest business cities in the Inland Empire, with about 5,400 establishments in its ZIP codes, more than any city we serve except Riverside. Integrity Tech is about 3 miles north in Rancho Cucamonga, close enough for same-day on-site help, and we support Ontario companies with managed IT, cybersecurity and compliance.

Built Around Ontario's Airport Economy

Ontario International Airport (ONT) handled more than 7.1 million passengers and 835,129 tons of cargo in 2025, and it hosts West Coast bases for Amazon Air, FedEx and UPS. That traffic supports a dense cluster of businesses we know well:

• Logistics and distribution. About 126 warehousing companies and 119 trucking firms. We keep warehouse Wi-Fi, scanners, label printers and WMS connections running across shifts.
• Aviation maintenance and aerospace. Repair stations at ONT such as Certified Aviation Services, and defense suppliers like PRC Composites, which makes composite containers largely for the Department of Defense. We help these shops meet DFARS, NIST SP 800-171 and CMMC requirements.
• Manufacturing. About 398 manufacturing establishments, the most of any city within 20 miles of our office.

What Ontario Companies Ask Us For

• Network separation between office, warehouse and shop-floor systems
• After-hours security monitoring for operations that run nights and weekends
• NIST 800-171 gap assessments, SPRS score help, SSPs and Microsoft GCC High for defense work
• On-site support for businesses near the airport
• VoIP phones and tested backups
