Responsive by design. Every email or portal ticket gets a real engineer within 20 minutes (Mon–Fri, 5 AM–6 PM) — ALL tickets, not just emergencies — so Fullerton businesses we support know their requests have been seen and are confident their needs are addressed promptly. We’re just as particular about the details: every change is documented, every ticket is followed through to the finish, and our co-founders, Kevin Nichols and Joe Kemp, are personally accountable for your experience.

IT support built around Fullerton businesses

Fullerton has a lively downtown, a large university community, and industrial areas with manufacturing and distribution companies that rely on dependable systems to move product.

Industrial businesses need networks that keep warehouse and ERP systems online, secure remote access for staff and vendors, and backups that can restore operations quickly after a failure or cyberattack.

Fullerton’s campuses, rail hub and defense roots

Fullerton is shaped by its schools. Cal State Fullerton is the city’s largest employer and, with nearly 40,000 students in 2019, the largest campus in the CSU system. Fullerton College is the oldest community college in continuous operation in California. For employers nearby that means a steady stream of student interns and part-time hires. Each one needs an account, a device and the right access on day one, and all of it removed on the last day. Accounts left open after someone leaves are one of the most common gaps in small-business security.

The city is also a rail hub. The Fullerton Transportation Center is served by Metrolink and by Amtrak’s Pacific Surfliner and Southwest Chief. For teams that commute by train and work from home part of the week, managed laptops, MFA and cloud phones matter more than the desk.

Defense work has deep roots here. An aircraft maker once ran a 293-acre campus in west Fullerton, and a major defense contractor still employs about 1,200 people in the city. The general aviation airport on Commonwealth Avenue, near the junction of the 5 and the 91, has its own industrial park. Suppliers that serve defense primes are being asked to prove their controls; see our aerospace and defense page. We reach Fullerton in about 15 miles via the 57 and the 91.

Between Cal State Fullerton, a busy downtown and industrial areas near the 91, Fullerton combines education, retail and logistics. Distributors here rely on warehouse Wi-Fi, scanners and ERP systems staying online through every shift, and we watch those networks 24×7×365.
