Where we work

Supporting businesses across San Diego County

San Diego County is really several business regions in one, each with its own mix of companies and IT needs. Here's how we help in each.

Central

Mission Valley & Kearny Mesa

Home to our headquarters and a dense mix of professional offices, medical groups and service companies along the I-8 and SR-163 corridors.

Coastal north

Sorrento Valley, Torrey Pines & UTC

One of the country's best-known life science and research hubs, where protecting research data and lab systems matters as much as day-to-day support.

Downtown

Downtown, Little Italy & Bankers Hill

Law firms, accountants and professional offices in high-rise buildings, where confidential client data and reliable email are non-negotiable.

North County

Carlsbad, Oceanside, Escondido & San Marcos

Manufacturers, medical practices and growing companies spread along SR-78 and the I-5 and I-15 corridors.

East County

La Mesa, El Cajon & Santee

Family-owned businesses, contractors and practices in the communities most often affected by wildfire-season power shutoffs.

South Bay

Chula Vista, National City & Otay Mesa

Logistics, trade and manufacturing businesses tied to the border region, where downtime can hold up shipments and payroll.

Cities we serve

On-site and remote IT support across San Diego County, including:

Mission Valley

Our headquarters. Offices along the I-8 and SR-163 corridors are a short drive away.

La Jolla

Professional and medical offices near UTC and the village, supported on-site and remotely.

La Mesa

East County offices along I-8, with on-site visits on Platinum and Titanium.

El Cajon

East County businesses where power-shutoff planning matters most during Santa Ana winds.

Chula Vista

South Bay businesses supported on-site across the county.

Local risks

San Diego risks we plan for

Good IT in San Diego isn't just about viruses and passwords. It's also about keeping your business running when the region throws something at you.

Wildfire power shutoffs

During Santa Ana winds, SDG&E can switch off power to reduce fire risk, sometimes for a day or more, especially in East County and the backcountry.

How we plan for it

Battery backup for key equipment, cloud backups that keep running, and a plan for working from another location.

Earthquakes

The Rose Canyon Fault runs through the heart of the city, including La Jolla and downtown. A strong quake could damage offices and the equipment inside them.

How we plan for it

Encrypted backups stored outside the region, tested restores, and a written recovery plan so you know who does what.

Targeted scams on local industries

Biotech, medical and legal firms hold exactly the kind of data criminals want, and San Diego has a lot of all three.

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 San Diego 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 San Diego 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.

Questions

Frequently asked questions

Do you come on-site anywhere in San Diego County?

Yes. On our Platinum and Titanium plans we come to your office anywhere in the county, from Oceanside and Escondido to Chula Vista and East County. Gold is remote support only: restores are done remotely, and an on-site visit is available as extra billable hours.

Where is your office?

Our headquarters is at 3111 Camino Del Rio N #400, San Diego, CA 92108, in Mission Valley.

What happens to our IT during a power shutoff?

It depends on how you're set up, which is why we plan for it. With battery backup, cloud-based email and files, and off-site backups, most teams can keep working from home or another location until power returns.

Do you work with medical practices and biotech companies?

Yes. We help medical practices with HIPAA safeguards and signed business associate agreements, and we help research companies protect their data with 24/7 security monitoring and tested backups.

How fast do you respond?

Call during business hours (8 a.m. to 5 p.m. Pacific, Monday to Friday) and our response target is 15 minutes, on every plan.

Can you work with our current IT person or provider?

Yes. Many San Diego businesses start with our free IT bill review or network assessment as a second opinion, with no obligation to switch.
