Managed IT Services in San Diego
NetSys runs IT for small and mid-sized businesses in San Diego: help desk, security, backups, Microsoft 365 and the network, for a flat monthly fee per user. We have run IT out of New York since 1998, and our engineers hold degrees in electrical and computer engineering. San Diego is served from Brooklyn, three hours behind us on Pacific time. Monitoring, help desk and remediation run remotely around the clock from Brooklyn, with coverage hours stated in Pacific time in the proposal. On-site commitments are arranged in advance and sized to the engagement. Most clients run between 10 and 75 seats, and every agreement is month to month.
The short answer
NetSys provides managed IT to businesses in San Diego: help desk with engineers on the line, 24/7 monitoring, patching, ThreatDown managed detection and response, Microsoft 365 and Intune administration, tested backups and vendor management, for a flat monthly fee per user. Delivery is remote-first from Brooklyn, with coverage hours stated in Pacific time, and on-site commitments are arranged in advance and sized to the engagement, up to a dedicated engineer with a drive time generally under an hour where regular presence is part of the scope. Most clients run between 10 and 75 seats, and every agreement is month to month.
How managed IT is delivered in San Diego
San Diego is served from Brooklyn, three hours behind us on Pacific time. Monitoring, help desk and remediation run remotely around the clock from Brooklyn, with coverage hours stated in Pacific time in the proposal. On-site commitments outside the tri-state area are arranged in advance and sized to the engagement: a mostly remote engagement needs no dedicated on-site engineer, while an engagement that calls for regular presence, such as a standing on-site day or two each week, gets a dedicated engineer whose drive time is generally under an hour, depending on where that engineer and your office are. Hardware ships pre-configured, so most projects need no visit at all. The buildings decide a lot of the design. UTC and Sorrento Valley have carrier choice, but Kearny Mesa industrial parks and Carlsbad offices often run on a single Cox circuit, and defense suppliers need CUI on segmented systems, so the compliance boundary shapes the network. The carriers we see most in San Diego are Cox Business, AT&T Business Fiber and Spectrum Business, and the failover design starts with which of them actually reach your building.
Who managed IT in San Diego is built for
Most of our San Diego work sits in Downtown San Diego, Sorrento Valley, UTC, Carlsbad and Kearny Mesa: biotech and medical-device companies on Benchling, defense contractors on Deltek Costpoint, medical practices on eClinicalWorks, professional firms on QuickBooks Online, hospitality businesses on Toast, and real estate firms on AppFolio. Each carries its own compliance load, which the section below covers, and each has a line-of-business vendor we coordinate with rather than work around. Companies with an internal IT person fit too; in that case we supply the monitoring, the security stack and the after-hours coverage behind them, and they keep their projects.
What tends to go wrong in San Diego
Two things shape the continuity design here. First, the weather and the grid: wildfire smoke and Public Safety Power Shutoffs in the East County are the recurring risk, so backups live out of region and failover uses cellular. Second, the attacks that actually land locally are ordinary ones, and the public record shows how they go: the May 2021 ransomware attack on Scripps Health, which diverted emergency patients and cost the system an estimated $113 million by its own disclosure. The controls in the next section are the ones that would have changed those stories.

A 22-person defense contractor in Kearny Mesa
The specific engagements behind this profile are under NDA, so it is written as a generalization rather than a named client. Our published, client-approved outcomes are in case studies.
A 22-seat defense contractors in Kearny Mesa that grew out of its setup: Deltek Costpoint plus a dozen browser tools, an Exchange Online tenant with no multifactor authentication, a Meraki firewall out of support and a Cox Business connection with no failover. Leadership wants one accountable provider instead of three vendors pointing at each other. The owner has become the help desk and the office manager keeps the passwords in a spreadsheet.
- ThreatDown MDR and EDR rolled out to every endpoint, with the console monitored around the clock
- Barracuda Email Protection placed in front of the mailboxes and SPF, DKIM and DMARC corrected so the company's own domain cannot be spoofed
- Intune enrollment for every laptop and phone, with Windows Autopilot registration for new hardware and a compliance policy that gates access to email and files
- Keeper password vault deployed so shared spreadsheets of passwords stop existing
- A written onboarding and offboarding checklist covering accounts, devices, access and hardware return
- Cutover in stages over three to four weeks, with the old provider's access removed at the end and no downtime during business hours
One provider is accountable for devices, network, Microsoft 365 and security. Staff call a help desk that fixes things, the insurer gets answers with evidence behind them, and leadership sees a quarterly roadmap instead of surprise invoices. The agreement runs month to month.
Complete managed IT, cybersecurity and help desk for a 20-seat organization
A 20-seat organization handed NetSys the whole of its IT. Devices, network, Microsoft 365 and vendors came under one agreement with 24/7 monitoring and a named account manager; endpoint protection, multifactor authentication, email protection and tested backups went onto all twenty seats; staff got a help desk with engineers on the other end; and every new hire now goes through a defined onboarding process with recurring phishing training. The write-up is limited to the scope delivered, with no outcome figures claimed.
Compliance in San Diego: the CCPA and what sits on top of it
If you hold personal information on a resident of California, the California Consumer Privacy Act as amended by the CPRA (Cal. Civ. Code § 1798.100 et seq.) requires reasonable security under § 1798.81.5 for any business holding Californians' personal information, gives consumers a right to sue after a breach caused by the lack of it, and sets the breach-notification duty under § 1798.82. The CCPA's consumer-rights obligations apply to businesses above the revenue and data thresholds. Healthcare practices add HIPAA and the Confidentiality of Medical Information Act, venture-backed companies answer to investor and enterprise-customer security questionnaires, and biotech and hardware firms protect intellectual property that a breach cannot restore. The managed agreement produces the evidence those rules ask for as a by-product: access reviews, patch reports, backup test results and a written incident response plan. Most firms we take over have none of it documented, which is the part that matters if you ever have to demonstrate compliance, so the documentation is built during onboarding rather than sold as a separate project.
What managed IT costs in San Diego
Managed IT is priced per user per month for a fully managed agreement, and the number moves with four things more than with headcount: how many servers you run, whether you need after-hours coverage beyond monitoring, how much compliance documentation you carry, and whether we are co-managing alongside an internal person or running everything. We quote from an assessment, not a phone call, and the agreement runs month to month. What belongs in the monthly fee versus what is billed separately is set out on our managed IT pricing page.
Who this fits, and who it does not
Best fit: 10 to 75 employees, one or two offices plus remote staff, already on Microsoft 365 or ready to move there, and either no internal IT or one person who is underwater.
Not a fit: businesses under five people, who are usually better served by the small-office baseline described in our five-person case study, or organizations over 250 seats, which need an internal team we can co-manage with rather than replace.

Managed IT Services in San Diego: FAQs
Do we have to sign a long contract?
No. Every NetSys agreement runs month to month, with no long-term contract and no early-exit penalty. The scope, the responsibilities on each side and the monthly figure are written down before you sign.
Is cybersecurity included or extra?
Included. Endpoint detection and response, multifactor authentication and Conditional Access, email protection, security awareness training and immutable backups are part of every managed agreement. The free external penetration test runs remotely before you hire us.
How much do managed IT services cost in San Diego?
The figure is quoted per user per month from an assessment of your environment, and it moves with server count, after-hours coverage, compliance requirements and whether you keep an internal IT person more than with headcount. Our managed IT pricing page explains what sits inside the monthly fee and what is billed separately, so quotes can be compared on the same basis.
Do you have an office in San Diego?
Our office is in Brooklyn, NY. San Diego is served from Brooklyn, three hours behind us on Pacific time. Outside the tri-state area the on-site arrangement is agreed before the engagement starts and sized to what it needs: none for a mostly remote account, and a dedicated engineer, generally within an hour's drive, where regular presence such as a standing on-site day or two each week is part of the scope. The proposal states that arrangement, coverage hours in Pacific time and any travel in writing, and the agreement runs month to month.
Does the CCPA apply to a small California business?
The consumer-rights side applies above thresholds ($25 million in revenue or data on 100,000 consumers), so many small businesses are outside it. Cal. Civ. Code § 1798.81.5's reasonable-security duty and § 1798.82's breach-notification duty apply to everyone, and the private right of action after a breach is what makes them expensive to ignore.
