Where we work

Managed IT services in Los Angeles County

Los Angeles County is bigger than most states, with business districts that feel like separate cities. Here's how we help in each.

Downtown

Downtown LA & the Arts District

Law firms, financial offices and creative companies in high-rises and converted warehouses, where secure email and fast support keep deals moving.

Westside

Century City, Santa Monica & Culver City

Entertainment, legal and tech firms handling confidential contracts, scripts and client data that can't leak.

The Valley

Burbank, Glendale & Van Nuys

Studios, production companies and the businesses that serve them, working with very large files and tight deadlines.

San Gabriel Valley

Pasadena & Arcadia

Engineering, architecture and financial firms that rely on powerful workstations and well-protected project files.

Harbor area

Long Beach & San Pedro

Logistics, shipping and trade businesses tied to the ports, where downtime can hold up containers and payroll.

South Bay

Torrance, El Segundo & Manhattan Beach

Aerospace suppliers, manufacturers and professional firms with strict security expectations from their customers.

San Fernando Valley

Managed IT services for San Fernando Valley businesses

From Burbank and Van Nuys to Sherman Oaks, Encino, Woodland Hills and Chatsworth, Valley businesses include studios and production companies, medical and dental offices, manufacturers and professional firms. Many work with very large files on tight deadlines, so fast workstations, reliable networks and tested backups matter as much as day-to-day support.

We support San Fernando Valley offices remotely on every plan, with 24/7 SOC security monitoring and a help desk from 8 a.m. to 5 p.m. Pacific, and Titanium adds a 24/7 help desk. On-site visits across the Valley are included on Platinum and Titanium.

Local risks

Los Angeles risks we plan for

LA businesses have seen how fast a normal week can turn. Good IT plans for it.

Wildfires and power shutoffs

The Palisades and Eaton fires in January 2025 closed whole neighborhoods for weeks, and Southern California Edison can cut power during high winds.

How we plan for it

Cloud email and files that work from anywhere, backups stored away from your office, and battery backup for key equipment.

Earthquakes

The Puente Hills fault runs beneath downtown Los Angeles, and the San Andreas and Newport-Inglewood faults aren't far away.

How we plan for it

Encrypted off-site backups, tested restores, and a written recovery plan so you know who does what.

Targeted attacks on valuable data

Law firms, studios and logistics companies hold contracts, unreleased content and shipping data that criminals want.

How we plan for it

24/7 SOC security monitoring on every plan, multi-factor sign-in, and email protection against phishing.

Coverage

How support works in Los Angeles County

Remote support, every plan

Most issues are fixed over a secure connection, usually while you're still on the phone with us.

On-site visits

A technician comes to your office anywhere in Los Angeles County on our Platinum and Titanium plans.

After-hours help

Titanium adds a 24/7 help desk and on-site emergency help when something can't wait until morning.
