Managed IT Services in Irvine, CA
For Irvine companies in the Spectrum, the Irvine Business Complex and the research park beside UC Irvine that want one IT company accountable for the whole environment: laptops, servers, Microsoft 365, the network, security, backups and every technology vendor. NetSys has done this work since 1998 and runs it remotely from Brooklyn, month to month, with engineers answering from 1 a.m. Pacific.
The short answer
NetSys provides managed IT services and the wider set of IT services an Irvine business needs from one company: help desk, 24/7 monitoring and patching, ThreatDown managed detection and response, Microsoft 365 and Intune administration, tested backups, IT consulting and vendor management, under one per-user monthly fee. Support is remote and cloud-based only. NetSys does not send engineers to Irvine, so configured hardware ships to you and your staff connect it. Engineers staff the help desk seven days a week from 1 a.m. to 8 p.m. Pacific, with monitoring and emergency service around the clock. Agreements run month to month.

How managed IT is delivered in Irvine
Irvine clients are supported from our Brooklyn office, and NetSys has no field staff in California, so the agreement says plainly that all work is remote. That rarely limits anything an Irvine office needs. NinjaOne gives our engineers live health data and remote control for every endpoint; Microsoft 365, Intune and Entra ID are administered in the cloud; Meraki and Fortinet firewalls are managed from their consoles. Equipment changes are staged ahead of time: laptops ship enrolled in Windows Autopilot, and network hardware ships preconfigured with a labeled diagram for your staff or the building's cabling contractor to install while an engineer confirms each connection. Onboarding meetings are scheduled in Pacific time, and every system we touch is documented in IT Glue. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time (1 a.m. to 8 p.m. Pacific), seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work.
Choosing an IT company in Irvine
Irvine has no shortage of IT companies, so compare them on things you can check. Ask who answers the phone at 7 a.m. Pacific and whether that person is an engineer. Ask for the written response commitments; ours are a ten-minute phone response and a thirty-minute remote response for critical issues, and thirty minutes and one hour for standard ones. Ask which security tools are included rather than sold later, how backups are tested, whether the contract runs month to month, and who owns the documentation if you leave. NetSys has run IT for businesses since 1998, keeps 98% of its clients, and has handled more than 30 ransomware incidents in three years with every one fully recovered.
Medical-device, gaming, mortgage and professional firms
Irvine's employers explain its IT needs. UC Irvine is Orange County's largest employer, Edwards Lifesciences runs its headquarters here, Blizzard Entertainment develops games here, and loanDepot moved its headquarters to the Irvine Spectrum. Around them sit device startups in the University Research Park, engineering and game studios, mortgage lenders and brokers, title and real estate companies, law and accounting firms and medical practices. The common thread is regulated or valuable data on a modern cloud stack. We manage Microsoft 365 and Intune for every device, keep product and design files under access controls that match each team, and handle the vendors behind the ERP, the EHR, the loan origination system or the document system, so your staff deal with one provider.
Continuity lessons from the Silverado Fire
On October 26, 2020 the Silverado Fire ran through the foothills in Santa Ana winds, and Irvine ordered mandatory evacuations north of Irvine Boulevard, then across neighborhoods between Great Park Boulevard and Bake Parkway. Voice of OC reported more than 90,000 residents evacuated and eleven schools emptied, and Southern California Edison said its equipment was under investigation as a possible cause. Offices that never saw a flame still lost a working day, because employees could not reach them or work from homes that had been evacuated. We design for that day: email, files and phones in Microsoft 365 and Teams, laptops that can work over a phone hotspot, backups stored outside Southern California, and a short call list that tells staff where and how to work.
What changes for staff in the first 30 days
For employees, the switch to NetSys shows up as a few concrete changes. In the first week, NinjaOne and ThreatDown install quietly on each device, and we ask everyone for ten minutes to set up multifactor sign-in with the Microsoft Authenticator app. In the second week, email starts passing through Barracuda, and suspicious messages land in a quarantine digest instead of the inbox. By the third week, anyone on aging hardware receives a new laptop that sets itself up at sign-in. Throughout, there is one number, one email address and a Teams channel for help, answered by engineers. At day 30 managers receive the documentation, a list of risks with costs and a technology budget for the next year.
Managed IT Services in Irvine: what NetSys delivers
Help desk and monitoring
- Unlimited help desk by phone, email and Teams, staffed by engineers rather than a ticket queue, with severe problems such as ransomware, systems down, no internet or email not working answered immediately by your dedicated engineer
- 24/7 monitoring of every server, workstation and firewall through NinjaOne RMM, with alerts an engineer acts on rather than forwards
Security, built in
- ThreatDown managed detection and response with EDR agents on every device, not just servers
- Microsoft Defender for Business, Entra ID Conditional Access and multifactor authentication across the Microsoft 365 tenant
Backups, devices and vendors
- Datto SIRIS or Veeam backups with immutable off-site copies, and live restores run on the schedule in the agreement with the result sent to you
- Intune and Windows Autopilot device management, so a new laptop ships sealed and configures itself at first sign-in
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.

What managed IT costs in Irvine
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.

Managed IT Services in Irvine: FAQs
How does managed IT work for Irvine organizations?
It is remote and documented. Monitoring and emergency service run 24/7, and the help desk is staffed by engineers from 1 a.m. to 8 p.m. Pacific, seven days a week. Severe events such as ransomware, systems down, no internet or email down go straight to your dedicated engineer, and your account manager has a real cell number. NetSys does not provide on-site service in Irvine; when hardware needs replacing it ships configured, and someone on your team connects it with our engineer on the line.
What IT services does NetSys offer Irvine businesses?
Managed IT for the whole environment, an engineer-led help desk, cybersecurity with managed detection and response, network security and firewall management, backup and disaster recovery, and IT consulting for assessments, cloud migrations and Microsoft 365 projects. We also run compliance work such as HIPAA and NIST SP 800-171 controls, Microsoft Copilot and AI rollouts, and vendor management. Most Irvine clients begin with managed IT and add projects as they need them. Our only free offer is a remote external penetration test within an agreed scope.
How does remote onboarding work for an Irvine business?
It takes three to four weeks for a typical 20-person office. We start with a video discovery session and a remote scan of devices, accounts and licenses, then install our agents and collect admin credentials into Keeper. Next come multifactor sign-in, email filtering and a verified backup. Laptops that need replacing are ordered, enrolled in Autopilot and shipped to each person. The final step is switching the help desk number over and removing the old provider's tools. Staff keep working throughout, because most of the change happens in the background.
How much do managed IT services cost in Irvine?
The fee is per user per month and comes from an assessment, so we do not post a number. What moves it: how many servers or on-premises applications you keep, the number of offices, compliance documentation such as HIPAA, NIST SP 800-171 or the FTC Safeguards Rule, and whether an internal IT person stays on in a co-managed arrangement. Everything routine is included, from the help desk and monitoring to security tools, backups, training and vendor calls. Hardware, licenses and projects such as a server retirement are quoted on their own.
Which California rules matter most for Irvine companies?
Mortgage lenders and brokers follow the FTC Safeguards Rule, including a report to the FTC within 30 days of a breach affecting 500 or more consumers. Medical practices follow HIPAA and California's Confidentiality of Medical Information Act. Larger companies may meet the CCPA's thresholds, and its cybersecurity audit regulations took effect in January 2026. Every business holding residents' personal information must maintain reasonable security under Civil Code 1798.81.5 and follow section 1798.82 after a breach. This is general information, not legal advice.
